Definitions
- the present invention relates to fluid conducting fittings in general and more specifically to fittings for connecting a reverse osmosis water purifier to a faucet.
- reverse osmosis water purifying apparatus utilize the water from a household or commercial system piped directly to the device, with overflow and drains for the concentrate or brine waste piped to the sewage disposal system.
- Sullivan et al teaches an improved flexible connector having multiple passageways inside with an e l astomeri c seal that accommodates angular movement between the input and output conduits.
- the connector also distributes compressive forces evenly with respect to the longitudinal axis.
- Grayson is concerned with the entire reverse osmosis liquid treating apparatus including the tank, liner, hoses and an automatic valve that controls the flow of effluent untreated liquid to a spout that extends exteriorly to the valve housing terminating at a discharge end.
- a manually actuated control valve modulates the flow of effluent-untreated liquid to the tank.
- Rosenbaum directs his attention to pipe joints for plastic pipe or tubing in the form of internal couplers for connecting adjacent ends of corrugated pipe.
- the coupling has projecting cleats of relatively thin material to facilitate flexing and is extruded and then molded in construction.
- the improvement eliminates these problems completely as the main structure is in one piece with fingers upstanding from the body interfacing with socket in a keeper sleeve that is easily indexed and set into place. No welding or pressure testing is now required and the assembly procedure is simplified as the sleeve simply snaps into place over the fingers maintaining attachment of the components.
- valve is opened to flush the deposits from within the purifier when the output decreases.
- the device is made of thermoplastic overtorquing of the valve leads to breakage or stripping of the threads which makes the purifier inoperative until a replacement is found as the unit will not function without the valve.
- the valve is now a cap-like structure that rotates only 5 partial turn from totally open to fully closed and the operation may be explained through directional arrows as an example "drip" in one direction and "flush” in another with either an arrow above the word or nearby as an alternative equally understandable nomenclature or combination thereof.
- the valve contains stops at each end removing the problem of excessive torque when the valve body is rotated. The movement is mechanically interrupted which is obvious to the user as further tension does not change the position.
- the improved two-way valve further permits the concentrate or brine waste flow to be diffused as it is released into the sink precluding splashing outside on the counter or floor.
- This object of the invention is accomplished using a series of small holes below the needle with the flow directed horizontally through a number of diminutive slots and the direct open area is covered by a diffuser. This arrangement allows air to mix with the water and aerate the waste flow completely eliminating the possibility of splashing even if something is in the way of the outlet flowpath.

- FIGURE 21 is an exploded view of the invention.
- FIGURES 1 through 21 The preferred embodiment, as shown in FIGURES 1 through 21 is comprised of a body 22 with a top 24, bottom 26 and side connector 28.
- the top 24 of the body contains a number of upwardly extending fingers 30 each having an inward indentation 32 on the outside surface.
- the body 22 is formed with a hollow chamber 34 inside as shown in FIGURE 14 with the fingers 30 integral with the top 28.
- FIGURES 14, 19 and 20 illustrate three separate fluid passageways within the body 22 that all start or terminate at the end of the side connector 28 with each having an inwardly tapered bore 36.
- the first passageway 38 is for suppling water from the faucet to the purifier with the inlet in the hollow chamber 34 of the body 22 and the outlet at the side connector 28 as illustrated in FIGURE 19.
- the second passageway 40 allows an unrestricted flowpath for overflow water when the purifier reservoir is full and the process continues to operate.
- the entry for this passageway 40 is at the side connector 28 and the exit is at the bottom 26 of the body 22 depicted in cross section in FIGURE 20.
- the third passageway, 42 shown in FIGURE 14 has the ingress at the side connector 28 and egress in the center of the body bottom 26. This passageway serves two purposes first to allow the concentrates or brine from the purifier to be disposed of in a metered manner and second to flush deposits from the apparatus when the reverse osmosis device becomes clogged.
- the side connector 28 is formed in triangular shape as shown in FIGURE 21 and has a plurality of splits 31 in the periphery around the three tapered bores 36. Each segment between the splits contains an inwardly facing internal pointed projection 29 that may interface and retain externally mounted tubes when forced inward to a straight configuration permitted by the resilience of the material.
- the bottom portion of the body 22 contains a set of partial turn external threads 44 on an inward stepped shoulder. These threads 44 unlike well known circumferential threads make only one partial turn around the periphery and terminate in a stop 46 created by the opposed thread. Further the inside of the bottom 26 is hollow except for a raised valve seat 48 .that is in alignment with the third passageway 42.
- This quick disconnect means consists of a jaw keeper sleeve 50 shown in FIGURE 16 by itself and in the exploded view 21 relative to the other elements.
- the sleeve 50 has a number of cavities 52 that enclose and retain the fingers 30 of the body 22 permitting the sleeve to be permanently attached to the top of the body.
- This sleeve 50 also includes a series of slots 54 completely therethrough located between the cavities 52 as depicted in FIGURE 21. when attached, the sleeve 50 becomes a structural part of the body 22.
- the slots 54 slideably receive a number of inwardly facing beveled locking jaws 56 preferably six illustrated in FIGURES 12, 13 and 21.
- Each jaw 56 has a groove 58 therein, illustrated best in FIGURE 12, and the sleeve 50 contains an upright projection 60 on the inside of the slot 54 such that the groove 58 in the jaw 56 slideably interfaces in the projection eliminating the possibility of improper installation.
- the bevel 62 of the jaw 56 is positioned nearest to the top 24 of the body 22 embracing the faucet adapter when the fitting is placed thereon.
- An enclosing ring 64 illustrated directly above the sleeve 50 in FIGURE 21, covers the top of the cavities 52 as the cavities are stepped outwardly on the upper portion allowing the inward indentation 32 to snap into place when the sleeve 50 and body 22 are assembled.
- the ring 64 is pressed into place in a circular groove 51 in the sleeve 50 serving only as an enclosure to cover the exposed cavities 52 and fingers 30 located therein.
- a compression spring 68 depicted in FIGURE 21, is contiguous with the top of the body 22 and sleeve 50 maintaining an upward locked position of the jaws 56 to the faucet adapter.
- a retracting collar 66 is the manually actuating part of the quick disconnect means and slideably passes over the fingers 30 of the body 22 and sleeve 50 maintaining the jaws 56 in an outward position when urged away from the body by the spring 68. This action permits the jaws to retract when manually forcing the collar 66 onto the body 22 thereby compressing the spring 64 allowing the jaws 56 to retract and thus permitting removal of the fitting from the faucet adapter.
- This method of quick disconnecting the fitting from the faucet adapter incorporates all of the improvements previously described.
- a resilient double lip seal 70 provides the water tight hermetic closure therebetween.
- the seal 70 is disposed within the hollow chamber 34 of the body 22 and comprises a resilient body folded double into a U-shaped ring. This configuration seals both on the doubled portion, illustrated in FIGURE 15, to the adapter and maintains the integrity of the seal against the cavity 34 due to be outward force of the water pressure from the faucet.
- FIGURES 17 and 18 illustrate connecting element which is a hollow tube retainer 72 shown by itself in FIGURES 17, 18 and FIGURES 14 and 19-20 in cross section.
- This retainer 72 has internal indentations 74 that snap over a series of barbs 76 on the split side connector 28.
- the retainer 72 holds, three flexible unitedly sheathed resilient tubes 78 depicted in dotted lines of FIGURE 1. These tubes 78 are connected to the reverse osmosis device and convert water or brine from the apparatus to the fitting for supply water, return waste and overflow.
- the retainer 72 is shaped like a hollow elongated triangle and is sized to fit the sheath of the tubes 78 holding all of the tubes in Place simultaneously.
- the indentations 74 are formed on the inside of the retainer 72 allowing them to tightly snap over the side connector barbs 76 maintaining a fluid tight tube seal created by the forward thrust of the installation snapping into place compressing the split portions of the connector 28 against the tubes with the internal pointed projections deforming the resilient material of the tube.
- the tubes enter the tapered bores 36 of the passageways 38, 40 and 42 completing the hermetic seal.
- the first end of the retainer 72 shown in FIGURE 17 locks over the side connector 28 and the second or other end of the retainer has an aperture the same configuration as the tube containing sheath 80 housing the three resilient tubes 78. The fit between the sheath 80 and second end of the retainer 72 is just tight enough to maintain a secure joint for the sheathed tubes 78.
- valve 82 is rotatably attached to the body 22 on the partial turn external threads 44.
- the valve 82 is formed much like an inverted cap as shown in FIGURES 8-11 and contains a pair of teeth 84 on the inside facing toward the center. The teeth 84 mesh with the partial turn external threads 44 formed into the body 22 and allow the valve free but limited rotation.
- FIGURE 7 illustrates the threads 44 that are formed in such a manner that they create a stop 86 when the valve is turned to its full rotation in either direction.
- the valve 82 is held in place with a snapping action during assembly overcoming the threads, locking it into place when the teeth 84 engage the threads 44.
- the threads 44 contain a ramp 45 on the outside only and the top of the thread is slightly radiused at the interface.
- the ramp 45 is only the width of the teeth 84 and function only for assembly purposes.
- the valve 82 further contains an integral cone shaped vented, needle 88 located in the center facing the body 22.
- the needle 88 is surrounded by a circular upstanding cup 90 and is in direct alignment with the seat 48 in the bottom 26 of the body 22.
- the valve 82 is rotated to its first position which maintains a very close space relationship between the needle 88 and the seat 4s allowing only a small amount of fluid to exit the fitting through the vents.
- the vents are illustrated in FIGURE 10 and are designated 88a for clarity.
- This controlled drip permits the purifier to function properly continually expelling concentrates or brine.
- the stop 86 prevents further rotation eliminating the problem of overtighting threads as the user can feel the stopped position.
- the second or open position allows a large amount of fluid to pass flushing deposits from the purifier through the third or vent passageway 42 when the valve 82 is rotated in the opposite direction. Again the stop 86 impedes the movement at the full open position.
- a diffuser 92 When in the second position in order to prevent splashing a diffuser 92, shown in FIGURE 6 singly, is pressed into a recess 94 in the valve 82 directly beneath the needle 88 using, as the attachment means, a raised neck 96 slightly smaller than the recess 94 allowing a slight interference fit.
- a series of slits 98 are formed around the diffuser 92 in communication with the vents 33a. These slits 93 are not in alignment therefore the waste water or brine is aerated by mixing with the surrounding air.
- the valve 82 also contains a number of overflow openings 100 around the outside of the bottom surface to allow water to drain from the second passageway 40 or overflow vent in the bottom of the body 22 and freely drain from the fitting.
- the faucet fitting is preferably constructed from injection molded thermoplastic or the like with the exception of the spring 68 which is steel and the seal 70 which is synthetic rubber or molded resilient plastic.
