Hole a.
Specific work process is as follows：
When vibroshock extensional motion, piston rod 8 drives piston valve assembly 6 to move upwards with respect to working cylinder 4, piston valve
Assembly 6 promotes fluid to pass through the cavity of resorption that bottom valve assembly 2 flows into working cylinder 4 from oil storage cylinder 1, and the fluid of working cylinder 4 epicoele passes through
Opening 9 enter middle cylinder 5, and via manual modulation valve assembly 3 fuel feed hole a enter manual modulation valve assembly 3, finally via
Manual modulation valve assembly 3 oil outlet b enter oil storage cylinder 1.When shock absorbers compression moves, piston rod 8 drives piston valve total
6 are become to move downward with respect to working cylinder 4, piston valve assembly 6 promotes fluid to flow into the epicoele of working cylinder 4 from the cavity of resorption of working cylinder 4,
The fluid of working cylinder 4 epicoele enters middle cylinder 5 by opening 9, and enters to start with via the fuel feed hole a of manual modulation valve assembly 3
Dynamic regulating valve assembly 3, finally enters oil storage cylinder 1 via the oil outlet b of manual modulation valve assembly 3.In sum, no matter vibroshock
Extensional motion still compresses motion, and the fluid in working cylinder 4 all manually must return oil storage cylinder 1 by regulating valve assembly 3.Manually
Rotation of adjustment knob 3-6 can drive regulating bolt 3-7 to rotate, by the threaded adjustment nut 3-8 that connects downwards (or upwards)
The certain displacement of motion, the up and down motion of adjusting nut 3-8 can change the spring force adjusting spring 3-9.Adjust the bullet of spring 3-9
Spring force is acted in valve ball 3-13 by valve core piston 3-10 and valve element 3-11, and valve ball 3-13 is joined with connect base 3-14
Combined pressure lives in oilhole a so that the fluid flowing into manual modulation valve assembly 3 from fuel feed hole a must reach enough to overcome spring force
Pressure just can back down valve ball 3-13 and via oil outlet b off-load.So, manually rotation of adjustment knob 3-6 can change
Become the oil liquid pressure within vibroshock, and then control the damping force of vibroshock.
The advantage of this structure is that valve element 3-11 in manual modulation valve assembly 3, valve ball 3-13 match and seals fuel feed hole a
Fluid, reduces requirement on machining accuracy, and is avoided that low discharge reveals the effect that ensure that pressurize oil sealing.
