Definitions

  • the present invention relates to a fluid delivery assembly comprising a tube, a port and a fitting for securing a tube to a port, particularly, but not exclusively a port of a valve such as a pneumatic braking valve.
  • the tube may be a flexible hose, pipeline or other conduit, through which fluid such as compressed air is supplied to or flows from the port.
  • conduits hoses or pipelines which convey compressed air around the braking system (for example, from the compressed air reservoir or to the brake actuators) are commonly connected to ports in fluid control valves by means of a fitting with screw thread which is connected to a corresponding screw thread provided on the housing around the port.
  • push to connect fittings such as those made by Kongsberg Automotive and sold under the trade mark Raufoss Couplings ® , which are pushed directly into the valve housing, are becoming increasingly popular.
  • An example of a prior art Raufoss Couplings ® fitting 10 is illustrated in Figures 1 a, 1 b and 1 c.
  • An exploded view of the fitting 10 is illustrated in Figure 1 a, whilst Figure 1 b shows the fitting in its assembled state, and Figure 1 c shows the fitting inserted in port 12 of a valve housing, and connecting a tube 13 to the port 12.
  • the prior art fitting 10 comprises a main cartridge body 14, having a first end 14a and a second end 14b, around which, towards the second end 14b, are mounted two exterior O-ring seals 16, 18 which, when the fitting is inserted into the port 12 provide a substantially fluid tight seal between the fitting 10 and the housing around the port 12.
  • the main cartridge body 14 is tubular, and, as such, has a longitudinally extending main passage which extends from the first end 14b to the second end 14b thereof.
  • Two interior O-ring seals 26, 28 are mounted in the main passage adjacent the first end 14a of the main cartridge body 14, spaced by a grip ring 30 and cone element 32.
  • the interior O-ring seals 26,28 are adapted to engage with the exterior surface of a tube 13 inserted into the fitting 10 so as to provide a substantially fluid tight seal between the fitting 10 and the tube 13.
  • the locking element 24 has a tubular portion 24a with a radially extending annular flange portion 24b which is located at an end of the tubular portion 24a.
  • the tubular portion 24a has a generally circular transverse cross-section, and extends along the main passage of the main cartridge body 14 to the second end 14b thereof, the tube 13 being located in the annular space around the exterior of the tubular portion 24a.
  • the tubular portion 24a thus acts to locate the tube 13 in sealing engagement with the interior O-ring seals 26, 28.
  • the first exterior O-ring seal 16 is located in a circumferential groove provided in the radially outward surface of the main cartridge body 14, whilst the second exterior O-ring seal 18 is trapped between the flange portion 24b of the locking element 24 and the locking ring 20.
  • the cone element 32 is also tubular and, when the fitting 10 is assembled, the first interior O-ring seal 26 is retained in a groove provided in the interior face of the cone element 32.
  • the second interior O-ring seal 28 is captured between the grip ring 30 and a shoulder provided in the interior surface of the main cartridge body 14.
  • the cone element 32 has a radially outwardly extending circumferential ridge 32a which is located in a corresponding circumferential groove in the interior surface of the main cartridge body 14, so as to retain the cone element 32, interior O-ring seals 26, 28 and grip ring 30 in place in the main cartridge body 14.
  • the star washer 22 is located around the main cartridge body 14 between a shoulder in the exterior surface of the main cartridge body 14 and the locking ring 20. It is annular and has a plurality of radially outwardly extending protuberance which are inclined towards the first end 14a. This ensures that the fitting 10 can be readily pushed, locking element 24 first, into the port 12 of a valve housing, as illustrated in Figure 1 c. The protuberances engage with the housing around the port 12, and as a result of this and their angle of inclination, ensure that the fitting 10 is retained in the port 12.
  • a brake valve assembly comprising a valve housing containing a port, a connector and an adapter, the connector and adapter together being configured to connect a tube to the port, the connector having a first sealing arrangement which is configured to provide a substantially fluid tight seal between the connector and the tube, and a connector screw thread which is releasably connected to a corresponding adapter screw thread provided on the adapter, the adapter having a second sealing arrangement which is configured to provide a substantially fluid tight seal between the adapter and the housing surrounding the port.
  • the adapter may be metallic, for example, made from brass.
