Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further.
Such as the control valve assembly of Fig. 1 to the clutch master cylinder shown in 8, include stop screw 7, piston 9, spool 6, close successively
Strip of paper used for sealing bowl 5, return unit 4 and spring base 3.
Piston 9: as shown in Figure 6 and Figure 7, is provided with the spacing keyway 90 placed for stop screw 7, piston 9 court in the middle part of piston 9
Be provided with valve opening 91 to one end of spool 6, valve opening 91 connects with spacing keyway 90, and the two ends outer wall of piston 9 is all arranged with annular
Piston packing 10；The effect of piston packing 10 is to prevent the oil in lubricating cup from spilling from the sidewall of piston.
Spool 6: as shown in Fig. 2, Fig. 3 and Fig. 8, the rounded tubulose of spool, it is arranged in valve opening 91, spool one end is closed,
Spool is sequentially provided with fuel feed hole 60, oil outlet 61, the fixture installed for sealing cup 5 and valve seat 63, fuel feed hole from front to back
60 are positioned at valve opening 91, and oil outlet 61 is positioned at the sidewall of spool, and oil outlet 61 is arranged at the sidewall of spool, and oil outlet 61 towards
The inwall of valve opening 91；The length of spool 6 is more than the length of valve opening 91.The tabular that valve seat 63 is rounded, the external diameter of valve seat 63 is more than
The external diameter of sealing cup 5.
Fixture: be positioned at the sidewall of spool sidewall, fixture is made up of ring-type bulge loop 62 and ring-shaped insert groove, and ring-shaped insert groove is situated between
Between ring-type bulge loop 62 and valve seat 63, sealing cup 5 is sheathed on ring-shaped insert groove and the surface of ring-type bulge loop 62.Ring-type bulge loop 62
External diameter less than the external diameter of valve seat 63.
Spring base 3: spring base 3 is cup-shaped, rim of a cup with the crimping turned up, spring base be attached at piston 9 one end and with work
Plug 9 together moves, and the sidewall of spring base 3 or diapire are provided with the drain oil 30 passed through for the clutch oil in oil outlet 61, resets
Part 4, sealing cup 5 and valve seat 63 are respectively positioned in spring base；The sidewall of spring base 3 is provided with 4 drain oils 30 facing each other, the end
Wall is provided with 1 drain oil 30.
Return unit 4: diapire in one end conflict spring base 3, other end conflict valve seat 63；Return unit 4 is volute spring, taper
The small end of spring is towards valve seat 63.
Sealing cup 5: be fixed on fixture, fixing leather cup by return unit 4 elastic force tightly be posted by piston 9 valve
The one end at place, hole 91；The cross section that axle center crossed by sealing cup 5 is L-shaped.
When control valve assembly is in open mode, and stop screw 7 compresses the one end at spool 6 fuel feed hole 60 place, return unit 4
Being compressed, oil outlet 61 is in outside valve opening 91；
When control valve assembly is closed, stop screw 7 at one end separates with spool 6 fuel feed hole 60, return unit 4
The oil outlet 61 of extruding spool 6 enters in valve opening 91, and piston 9 surface at valve opening 91 place is close to by sealing cup 5.
When above-mentioned control valve assembly is applied to clutch master cylinder, it is arranged in the cylinder body 1 of clutch master cylinder, cylinder body 1
It is provided above cup 1c, cup 1c and is used for installing lubricating cup 18, in lubricating cup 18 and cup, be placed with clutch oil.
Being additionally provided with cylinder inner spring 2 in cylinder body 1, cylinder inner spring 2 is conflicted the outer rim crimping of spring base 3, the strength of cylinder inner spring 2
Degree coefficient is much larger than the stiffness factor of volute spring 4 (return unit), and briefly cylinder inner spring 2 is harder, is difficult to be compressed.
As depicted in figs. 1 and 2, when control valve assembly does not stresses, cylinder inner spring 2 extrusion spring seat 3, spring base to the right
3 abut piston 9, make the spacing keyway 90 on piston 9 conflict completely with stop screw 7, make stop screw 7 that spool 6 is produced one
Individual thrust to the left, and thrust is more than the elastic compression force of volute spring 4, spool 6 is released valve opening 91 a small distance, makes valve
Oil outlet 61 on core 6 is positioned at outside valve opening 91, cuts sealing cup 5 contactless with piston 9 surface at valve opening 91 place, makes lubricating cup 18
Interior clutch oil can flow in piston 9 smoothly in oil circuit 1a, and flows out in oil outlet 61 in the middle part of spool 6, enters
Enter in spring base 3, then the drain oil 30 passing through spring base 3 surface enters in cylinder body 1, and (as shown in dashed line in figure 2, i.e. clutch is oily
The path of flowing), finally the oil-out 1b from cylinder body 1 surface flows out, and forms the loop of a clutch oil flowing.
As shown in figures 1 and 3, when control valve assembly receives push rod 14 pressure to the left, and pressure is more than cylinder inner spring 2
Elastic force, cylinder inner spring 2 is compressed, and control valve assembly is overall to be advanced to the left by piston 9 inside cylinder body 1, loses stop screw 7
Conflicting, spool 6 is pressed in the valve opening 61 of piston 6 under the effect of volute spring 4, and makes the sealing cup 5 on spool 6 surface tight
The tight piston face compressing valve opening 91 place, makes control valve module enclosure and closing, and clutch oil cannot pass through control valve assembly.
Realize push rod by control valve assembly the indirect of oil circuit break-make in lubricating cup is controlled, be effectively improved clutch master cylinder
Sensitivity.
The above makes the preferred embodiment of the present invention, for the person of ordinary skill of the art without departing from this
On the premise of bright principle, it is also possible to make some modification and improvement, these also should be regarded as protection scope of the present invention.
