Including valve seat, base, valve block and spring, on valve seat, valve block is arranged on base floor installation, there is valve opening, spring on valve seat
Between valve block and valve seat.Due to spring generally use helical spring of the prior art, due to the precision difficulty handle of spring
Hold, stability is bad, and spring is easily deformed failure, the defects of causing seal failure, the short life of damper.Secondly, piston rod
The top of inserting end can produce collision with sleeve bottom surface, cause piston rod inserting end during it is moved back and forth vertically
Vertex abrasion is serious, causes piston assembly sealing uneven, the defects of causing sealing effectiveness difference.Furthermore above-mentioned piston rod is close
One end of mounting seat is provided with oil sealing and guider, due to being easily deformed at the oil seal lip, causes seal failure or causes leak
Phenomena such as oily；The connection end outer peripheral face of piston rod is provided with L-shaped step surface, and mounting seat abuts forming face face with the L-shaped step surface and connect
Touch, but due to two contact surfaces be in being mutually perpendicular to relation, after the connection end of piston rod is threadedly coupled in place with mounting seat,
It is axially displaced that its can be limited, but because the contact surface between mounting seat and L-shaped step surface can only be spacing in the axial direction, can not be right
Its progress of gap on radial end face is spacing, in use for some time, can still there is the potential safety hazard of piston rod abjection.On
To state piston rod and generally include the body of rod and the insertion rod inserted in mounting seat, insertion rod is generally welded to rod end, but due to weldering
Connect operation has error unavoidably, it is difficult to ensures insertion rod and the concentricity of the body of rod, causes damper job insecurity, cause piston rod
There is the problem of early fatigue fracture failure；In addition, the top of one end that piston rod is stretched into sleeve is in its reciprocal shifting vertically
In dynamic process, collision can be produced with sleeve bottom surface, cause piston rod inserting end vertex abrasion serious, cause piston assembly to seal
It is uneven, the defects of causing sealing effectiveness difference, and also sleeve bottom surface is provided with bottom valve, due to the shock-absorbing buffering effect of sleeve bottom surface
Difference, during shock, bottom valve can also be destroyed, and reduce service life.
