Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
As shown in Figure 1, being mainly made of circlip 1, O-ring 5, valve body 2, gasket 3 and control valve core 4,2 inner hole of valve body is
Shoulder hole structure, gasket 3 as shown in Figure 3 are assemblied in the large hole of 2 inner hole of valve body, the 2 inner hole interference of gasket 3 and valve body
Cooperation and the first order step surface limit by being connected in valve body 2 between large hole and smaller hole, guarantee inner sealing, control valve core
4 are assemblied in the smaller hole of 2 inner hole of valve body and adjacent with gasket 3, and the smaller hole of 4 valve body of control valve core, 2 inner hole is far from close
The second level step of diameter diminution is additionally provided at 3 one end of packing, 90 ° of chamfered transitions are arranged in step, so that control valve core 4 is limited in
It is moved axially between first order step and second level step.
As shown in figure 4, control valve core 4 is provided with the valve opening along valve body 2 inner hole axial direction among itself, adjusted for parameter,
On circumference it is circumferentially spaced open in uniform way there are four along valve body 2 inner hole axial direction arc groove.
As shown in figure 5,2 one end of valve body is pin end, the other end is female connector, and is fast insertion type joint.This is practical new
The push-in flow control valve D of type clutch is mounted between oil pipe C and working cylinder E, and the pin end of flow control valve D connects working cylinder E,
Female connector connects oil pipe C.
As depicted in figs. 1 and 2, grafting oil pipe and circlip through slot is opened up in end outer wall in 2 one end of valve body, circlip 1 fills
It fits on the circlip through slot of valve body 2, is assembled on circlip through slot by circlip 1 and the assembly of oil pipe is limited；O-ring 5 fills
It fits in the O-ring slot that 2 other end of valve body opens up, guarantees external sealing.
In specific implementation, control valve core 4 is plastic material, and valve body 2 is plastic material, and 1 material of circlip is metal material, O
Type circle 5 is rubber material, and gasket 3 is rubber material.
The course of work of the utility model is:
As shown in fig. 6, when the systems are operating normally, stepping on clutch pedal A, pedal A pushes master cylinder B piston, liquid medium
Enter flow control valve D by oil pipe C, oil pressure pushes control valve core 4 to move to the right, at this time oil pressure by 3 inner hole of gasket
It can pass through from four circumferential arc grooves of control valve core 4 and intermediate central through hole, into working cylinder E, realize system function,
This process liquids medium is unimpeded, on pedal force also without influence.
As shown in fig. 7, when the systems are operating normally, unclamping clutch pedal A, liquid medium is back to flow from working cylinder E
Control valve D, oil pressure pushes control valve core 4 to move to the left at this time, and is bonded with 3 end face of rubber pad, and oil pressure can only be from control at this time
The central through hole of spool 4 processed passes through, to reduce fluid flow, slows down pedal opening speed.
