Description
Technical field
The present invention relates to electric-controlled fuel injector internal structure, specially a kind of spacing adjustment pipe of fuel injector is integrally tied with filter screen
Structure.
Background technology
Fuel injector is applied to pulsating liquid delicate metering and atomization, such as engine fuel metering and Combustion System, fuel injector
Receive the fuel injection pulse signal that ECU (electronic control unit) is sent, accurately control fuel injection amount.
The structure of fuel injector is mainly made up of electromagnetic mechanism, valve body mechanism, atomising mechanism, metrological service and runner mechanism,
The electromagnetic mechanism includes cored, includes filter screen in the runner mechanism.
In the traditional structure of fuel injector, the iron core located at shell inner hole middle and lower part and by upper and lower oil inlet pipe and every
Magnetic tube is positioned, and the filter screen is at the necking of the oil inlet pipe mouth of pipe, and the spacing adjustment pipe is located at core interior, and its purposes is
Regulation is acting downwardly on the decrement of the compression spring on armature.
In above-mentioned traditional structure, due to being to cause oil spout more than parts and structure is unreasonable and cause assembly precision low
The major reason of device job insecurity.
The content of the invention
In view of the shortcomings of the prior art, the technical problems to be solved by the invention are to propose a kind of further raising oil spout
The spacing adjustment pipe of fuel injector and the filter screen integrative-structure of device job stability.
The spacing adjustment pipe of fuel injector and filter screen integrative-structure of above-mentioned technical problem are can solve the problem that, its technical scheme includes setting
It is provided with shell inner hole middle and lower part and in upper and lower oil inlet pipe and the iron core of plunger tube axially position, the core bore of the iron core
Spacing adjustment pipe is to adjust the decrement for the compression spring being acting downwardly on armature, except that the spacing adjustment pipe is set
At the upper end aperture of iron core core bore, the filter screen filtered to oil inlet pipe inner fluid is in the pore of spacing adjustment pipe, institute
Filter screen is stated to be integrated with spacing adjustment pipe making shaping.
For ease of assembling positioning, the part suitable for reading of the spacing adjustment pipe increases and is pressed downward being loaded on as limitation adjustment pipe
The axial limiting of depth in iron core core bore.
For ease of the axial limit assembled positioning, the lower mouth subcontract of the spacing adjustment pipe and be set with as compression spring
Position.
Beneficial effects of the present invention：
1st, in structure of the present invention, spacing adjustment pipe is designed and produced with filter screen and is integrated, a part is reduced,
Cost is reduced, assembly precision is improved.
2nd, integral structure of the invention, is conducive to return spring, so as to improve the stability of armature motion.
3rd, integral structure of the invention, is conducive to the adjustment of dynamic flow.

Embodiment
Illustrated embodiment is described further to technical scheme below in conjunction with the accompanying drawings.
The spacing adjustment pipe of fuel injector of the present invention and filter screen integrative-structure, its technical scheme include filter screen 8, spacing adjustment pipe 5,
Iron core 4, oil inlet pipe 2, plunger tube 3 and compression spring 7.
The iron core 4 is located at the middle and lower part of the endoporus of (fuel injector) housing 1, and by press-fiting in the oil inlet pipe 2 of the endoporus of housing 1
(upper) and press-fit plunger tube 3 (bottom) axially position in the endoporus of housing 1, armature 6 be provided with the plunger tube 3 of the lower section of iron core 4,
Compression spring 7 is pressed between iron core 4 and armature 6, as shown in Figure 1.
The spacing adjustment pipe 5 is level Four step pipe, and the top-down caliber of level Four step pipe is gradually reduced, spacing adjustment
Pipe 5 is pressed downward feeding into from the core bore mouthful of iron core 4, and by the way that in the core bore of second level body tight fit iron core 4, first order body will
The spacing adjustment axial limiting of pipe 5 is plugged in compression spring 7 in the core bore mouthful of iron core 4, fourth stage body, third level body axial direction
Spacing compression spring 7, as shown in Figure 1.
In the second level body of filter screen 8, the filter screen 8 makes shaping with spacing adjustment pipe 5 and is integrated, and such as schemes
Shown in 1.
