514 bottoms are provided with first oil guide groove 511 and second oil guide groove 512 corresponding and highly consistent to the lateral oilhole 710, set
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
Slot 512 and 710 on and off of 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 on 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 slot, 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 described sleeve pipe is provided with clamping portion 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 clamping portion 610, valve block card slot 523 and
Banking stop card slot（Attached drawing is not shown）, adjuster 510, valve block 520 and banking stop 530 be pressed in the piston 300 and
Between casing 600.
Compressing valve system includes the compression fluid access 320 being set on piston and can close the compression fluid access 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 access 330 being set on piston and can close answering for the healing fluid access 330
Former valve block 420 forms；It includes to assist restoring valve block 810 and the auxiliary being restored valve block 810 often that auxiliary, which restores valve assembly 800,
Partition auxiliary restores the auxiliary that oil circuit direction is suppressed and restores shrapnel 820.
Third 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 open state, 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, see that Fig. 4, the compression valve block 410 of compressing valve system are opened, oil is logical by compression fluid
Road 320 enters 300 epicoele of piston from 300 cavity of resorption of piston, in addition, a road binders from oil-through-hole 720 and side to oilhole 710 along
One oil guide groove 511 is open-top by valve block 520 with the second oil guide groove 512, into annular groove 514, then on piston 300
Chamber, the oil mass to circulate in this way increase, and 300 resistance to compression pression of piston becomes smaller, and specific flow direction is shown in arrow.
Damper restores（It stretches）When, see that Fig. 5, auxiliary restore the auxiliary in valve assembly 800 and restore the opening of valve block 810, storage
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
Access 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, at this point, 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 being restored in damper（It stretches）When, in regulating valve system, the oil of 300 epicoele of piston can only lead to
It crosses the first oil guide groove 511 and flow back into 300 cavity of resorption of piston, the oil adjusted when stretching is restored in the damping when damper that compares compresses
Liquid regurgitant volume is less than flow when compression, then the damping that is restored when stretching is slightly larger, so that it may so that the speed restored
Slow down, reduce the Sudden Changing Rate of damper, improves the comfort of seating.
When the first oil guide groove and the second oil guide groove are not conducted with lateral oilhole, damper working condition 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 is logical by compression fluid
Road 320 enters 300 epicoele of piston from 300 cavity of resorption of piston, and specific flow direction is shown in arrow；
Damper restores（It stretches）When, see that Fig. 7, the recovery valve block 420 of resetting valve system are opened, oil passes through healing fluid access
330 enter 300 cavity of resorption of piston from 300 epicoele of piston, and 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 the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
