See Fig. 1, a kind of regulating valve system of damping barbed chair damper, including piston rod 700, the piston rod 700
Hypomere is hollow structure and is symmetrically arranged with lateral oilhole 710, which forms oil-through-hole 720, covered on piston rod 700
Equipped with casing 600, adjuster 510 and valve block 520, piston 300 is connected by locking nut 740 and piston rod 700.
See that Fig. 2-3, adjuster 510 are provided with the annular groove 514 for accommodating the valve block 520, valve block 520 can be in the annular
514 interior lines sexuality of groove, 514 opening of annular groove, which is provided with, is limited in the valve block 520 in the annular groove 514
Banking stop 530,514 bottom of annular groove is provided with first oil guide groove corresponding and highly consistent to the lateral oilhole 710
511 and second oil guide groove 512, casing 600 adjuster 510, valve block 520 and banking stop 530 can be driven to rotate synchronously so that the
One oil guide groove 511 and the second oil guide groove 512 and 710 on and off of lateral oilhole, the first oil guide groove 511 and annular groove
514 bottoms intersection are arranged jagged 513, and the first oil inlet and outlet 521 and the second oil inlet and outlet 522, valve are provided on valve block 520
Piece 520 can be pressed in 314 bottom of the annular groove and close the first oil guide groove 511, the second oil guide groove 512, and at this time described first
Oil guide groove 511 is connected by the notch 513 with first oil inlet and outlet 521.
600 one end of casing 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 limit
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.
Preferably, 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, Fig. 4 is seen, oil is from oil-through-hole 720 and side to oilhole 710 along the first oil guide groove 511
It is with the second oil guide groove 512 that valve block 520 is open-top, into annular groove 514, then into 300 epicoele of piston, circulate in this way
Oil mass increase, 300 resistance to compression pression of piston becomes smaller, and specific flow direction is shown in arrow.
Damper restores（It stretches）When, see Fig. 5, the valve block 520 in adjuster 510 falls, and is pressed in 314 bottom of annular groove
First oil guide groove 511, the second oil guide groove 512 are closed, the first oil guide groove 511 is passed in and out by the notch 513 and described first
Hydraulic fluid port 521 is connected, at this point, the oil of 300 epicoele of piston can only be from the first oil inlet and outlet 521, notch 513, the first oil guide groove 511
300 cavity of resorption of piston is flowed into lateral oilhole 710 and oil-through-hole 720, 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；
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.
