Pipe 600 can drive adjuster 510, valve block 520 and banking stop 530 to rotate synchronously, so that the first oil guide groove 511 and the second Oil Guide
Groove 512 and 710 on and off of the lateral oilhole, the first oil guide groove 511 is provided with scarce with 514 bottom intersection of annular groove
Mouthfuls 513, the first oil inlet and outlet 521 and the second oil inlet and outlet 522 are provided with valve block 520, and it is recessed that valve block 520 can be pressed in the annular
The first oil guide groove 511, the second oil guide groove 512 are closed in 314 bottom of groove, and first oil guide groove 511 passes through the notch at this time
513 are connected with first oil inlet and outlet 521.
600 one end of casing is provided with Access Division 610, and the other end, which is provided with, adjusts plectrum 620, the adjuster 510, valve block
520 and banking stop 530 be both provided with adjuster card slot 515 corresponding with the Access Division 610, valve block card slot 523 and spacing
Piece card slot（Attached drawing is not shown）, adjuster 510, valve block 520 and banking stop 530 are pressed in the piston 300 and casing
Between 600.
Preferably, support pad 742 is provided between adjuster 510 and piston 300.
Compressing valve system includes the compression fluid path 320 being arranged on piston and can close the compression fluid path 320
Compression valve block 410, and the compression bullet shrapnel that will often compress valve block 410 normal 320 direction of closed compression fluid passage and suppress
411；Resetting valve system includes the healing fluid path 330 being arranged on piston and can close answering for the healing fluid path 330
Former valve block 420 forms；Auxiliary recovery valve assembly 800 includes auxiliary and restores valve block 810 and the auxiliary recovery valve block 810 often will
Partition auxiliary restores the auxiliary suppressed in oil circuit direction and restores shrapnel 820.
The 3rd oil sealing 630 is provided between casing 600 and piston rod 700.
It is to drive adjuster 510 to control by the rotatable casing 600 being set on piston rod 700 that specific damping, which is adjusted,
Oil passage opening, to adjust damping force size.
When the first oil guide groove 511 and the second oil guide groove 512 are conducted with lateral oilhole 710, when increasing compression or restoring
Fluid flow, damper are in software feature state；
Specifically, when damper compresses, Fig. 4 is seen, the compression valve block 410 of compressing valve system is opened, and oil passes through compression fluid path 320
300 epicoele of piston is entered from 300 cavity of resorption of piston, in addition, a road binders is led from oil-through-hole 720 and lateral oilhole 710 along first
Oil groove 511 is open-top by valve block 520 with the second oil guide groove 512, into annular groove 514, then into 300 epicoele of piston,
The oil mass increase so circulated, 300 resistance to compression pression of piston diminish, and specific flow direction is shown in arrow.
Damper restores（Stretching）When, see Fig. 5, the auxiliary that auxiliary is restored in valve assembly 800 is restored valve block 810 and opened, stores
Oil in hydraulic cylinder assembly 100 adds to piston cavity of resorption, meanwhile, the recovery valve block 420 of resetting valve system is opened, and oil passes through healing fluid
Path 330 enters 300 cavity of resorption of piston from 300 epicoele of piston, and the valve block 520 in adjuster 510 falls, and is pressed in annular groove
The first oil guide groove 511, the second oil guide groove 512 are closed in 314 bottoms, and the first oil guide groove 511 passes through the notch 513 and described the
One oil inlet and outlet 521 is connected, and at this time, the oil of 300 epicoele of piston can only be led from the first oil inlet and outlet 521, notch 513, first
Oil groove 511 enters lateral oilhole 710 and oil-through-hole 720 flows to 300 cavity of resorption of piston, and specific flow direction is shown in arrow.
It should be noted that restored in damper（Stretching）When, in regulating valve system, the oil of 300 epicoele of piston can only lead to
Cross the first oil guide groove 511 and flow back into 300 cavity of resorption of piston, the damping when damper that compares compresses, restores the oil adjusted during stretching
Liquid regurgitant volume is less than flow during compression, then damping when that is restoring stretching is slightly larger, so that it may so that the speed restored
Slow down, reduce the Sudden Changing Rate of damper, improve the comfort of seating.
When the first oil guide groove and the second oil guide groove are not conducted with lateral oilhole, damper working status and conventional damping
Device is the same, is at this time hardware features state；
Specifically, seeing Fig. 6, when damper compresses, the compression valve block 410 of compressing valve system is opened, and oil passes through compression fluid path 320
300 epicoele of piston is entered from 300 cavity of resorption of piston, specific flow direction is shown in arrow；
Damper restores（Stretching）When, see Fig. 7, the recovery valve block 420 of resetting valve system is opened, and oil passes through healing fluid path 330
300 cavity of resorption of piston is entered from 300 epicoele of piston, specific flow direction is shown in arrow.
It should be noted that in the first oil guide groove 511, the second oil guide groove 512 and lateral oilhole 710 by fully on to pass
It is a continuously adjustable process during closing, then that is the damping of the damper is continuously adjustable, adjusting need to only stir
Adjusting plectrum 620 drives casing 600 to rotate, you can realizes that the damping of damper is adjusted.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：It is all according to
The equivalence changes that structure, shape, the principle of the present invention is done, should all be covered by within protection scope of the present invention.
