Can not open in oil pressure is too small, at this moment by the B4 of oil through two, the excessively oily passage A of the B1 of oil through one are crossed between oil ring epicoele fluid
Throttle orifice B3 in gap B7, and regulation valve body, flows to piston lower portion.Produce and restore low resistance.
When the B1 of the oil through one and B4 of oil through two disconnects, the cavity pressure that oils increase, unnecessary fluid is on piston 30
Duct throttle valve plate 31 is opened, flow into lower oil cavitie, produce restore high-damping.
When shock absorbers compression, when the B1 of oil through one and the B4 of oil through two are communicated, the volume of lower oil cavitie reduces, the oil having more
Throttle orifice B3, excessively oil ring gap B7 on a part of adjusted valve body 27 of liquid, excessively oily passage A, the B1 of oil through one and oil through two
B4 flows into the intracavity that oils；The adjusted B2 of hole two of a part of fluid, steel ball 29, excessively oily passage A, the B1 of oil through one, flow into upper oil cavitie,
Produce compression low resistance.
When the B1 of the oil through one and B4 of oil through two disconnects, lower oil cavitie volume reduces, and unnecessary a part of fluid is through living
Reinforcing compression valve block 26 is opened in duct on plug 30, flows into upper oil cavitie, and another part fluid is by the duct on compression valve body 5
Compression valve block 8 is opened, oil storage cylinder is flowed into.Produce compression high-damping.
With the change of vehicle drive condition, by driving indoor bracing wire, the regulation on hollow piston rod 13 is pulled to draw
Arm 18, makes solid piston bar 14 and hollow piston rod 13 mutually rotate, and the B1 of the oil through one and B4 of oil through two can be interconnected
Or disconnect, so as to adjust the size of resistance of shock absorber.
