the bottom throttle seat 33 comprises a cover part 331 and a rod part 332, the cover part 331 is located above the throttle plate 32, the rod part 332 penetrates through the throttle plate 32, the valve plate 34 and the valve seat 31 to the valve seat lower groove 315, one side of the cover part 331 facing the throttle plate 32 is provided with a first convex ring 3311 and a second convex ring 3312, the first convex ring 3311 abuts against the throttle plate 32, the second convex ring 3312 is located on the outer side of the first convex ring 3311, a gap is left between the second convex ring 3312 and the throttle plate 32, and the throttle groove 321 extends from the edge of the throttle plate 32 to a position between the first convex ring 3311 and the second convex ring 3312;
and a compensating spring 35 located between the bottom end of the stem 332 and the valve seat 31.
As shown in fig. 1 and 3, the compression valve assembly 3 is mounted to the bottom of the damper.
In the embodiment, the area enclosed by the first protrusion ring 3311 is communicated with the upper valve seat groove 313, and a compression oil groove 3321 may be provided on the side of the rod portion 332 of the bottom valve seat 33, where the compression oil groove 3321 extends from above the throttle plate 32 to the lower valve seat groove 315; alternatively, the valve plate 34 and the throttle plate 32 may be provided with through holes, but the through holes are aligned.
Under the action of the compensation spring 35, the compensation spring 35 pulls the bottom throttle seat 33 downward, so that the first convex ring 3311 of the cap 331 is pressed against the throttle plate 32, the surface between the valve plate 34 and the support ring 314 is in surface contact, the size of the throttle plate 32 is substantially the same as that of the valve plate 34, and the force of the compensation spring 35 is not enough to cause excessive deformation of the throttle plate 32 and the valve plate 34, at this time, a gap between the second convex ring 3312 and the throttle plate 32 exists, and oil can smoothly pass through the gap between the second convex ring 3312 and the throttle plate 32.
When the piston rod 4 of the damper is retracted by impact force, the bottom throttle seat 33 is pressed downwards, at this time, if the impact force is weak, the pressure of the bottom throttle seat 33 cannot make the throttle plate 32 and the valve plate 34 deform greatly, the oil in the working cylinder 2 passes through a gap between the second convex ring 3312 and the throttle plate 32 basically without hindrance, when reaching the first convex ring 3311, the first convex ring 3311 and the throttle plate 32 are squeezed open, the oil passes through the gap to reach the enclosed inner area of the first convex ring 3311, passes through the compressed oil groove 3321 to reach the upper valve seat groove 313 and the lower valve seat groove 315, and finally enters the oil storage cylinder 1; when the impact force is strong, the bottom throttle seat 33 moves downward, the throttle plate 32 and the valve plate 34 are deformed by the first boss 3311, and the second convex ring 3312 is close to or even in contact with the upper surface of the throttle plate 32, at this time, the oil in the cylinder 2 can only enter between the first convex ring 3311 and the second convex ring 3312 through the throttle groove 321, then the first convex ring 3311 and the throttle plate 32 are squeezed open, the oil passes through the inner area formed by the first convex ring 3311, passes through the oil compression groove 3321 to reach the upper groove 313 and the lower groove 315 of the valve seat, and finally enters the oil storage cylinder 1, namely, when strong impact force is applied, the speed of oil flowing into the oil storage cylinder 1 can be slowed down, so that the piston rod 4 is slowly retracted, the piston rod 4 is prevented from directly touching the bottom due to large flow, and when the impact force is smaller, the piston rod 4 can retract at normal speed, so that the piston rod is more comfortable.
When the piston rod 4 rebounds, the oil in the oil storage cylinder 1 reaches the upper groove 313 of the valve seat through the lower groove 315 of the valve seat and the flow hole 312 in sequence, and pushes the valve plate 34, the throttle plate 32 and the bottom oil valve seat 33 upwards, so that the compensation spring 35 is compressed, and the oil flows back into the working cylinder 2 through the space between the valve plate 34 and the support ring 314.
The valve plate 34 that this embodiment is preferred is provided with a plurality ofly, and a plurality of valve plates 34 stack in proper order, can set up different quantity valve plate 34 as required, and it needs the required power of deformation to be big more when valve plate 34 is more.
In the preferred embodiment, an annular groove is formed at the bottom end of the rod 332, one end of the compensating spring 35 is fixed in the annular groove, the other end of the compensating spring abuts against the valve seat 31, and the compensating spring 35 is preferably a compression spring.
In the preferred embodiment, an oil passing port 311 is arranged on one side of the bottom of the valve seat 31, the oil passing port 311 communicates the outer side of the valve seat 31 with the valve seat lower groove 315, wherein the oil passing port 311 is only arranged on one side of the circumferential direction of the valve seat 31, the valve seat 31 can communicate the oil storage cylinder 1 with the valve seat lower groove 315 only through the oil passing port 311, at this time, the whole damper can be inclined or even transversely used, specifically, one side of the oil passing port 311 faces the lowest side, oil is located below, the oil passing port 311 is immersed all the time, the entering of compressed air can be avoided, the inflow and outflow of oil cannot be influenced, an inward protruding boss 11 is preferably arranged on the oil storage cylinder 1 corresponding to the oil passing port 311 at this time, and the outside of the oil storage cylinder 1 is inward recessed when being installed, so that the valve seat 31 can be well placed by aligning the oil passing port 311 with the boss 11, and a user can know the position of the oil passing port 311 according to the recess at the outside, that is, it can be understood that the recess needs to be directed downward when the damper is used in an inclined or horizontal position.
