Shock absorber e.g. for mechanical devices, has cylinder with piston rod axially movable which can be stationary and movable against spring action, by spring and axially adjustably stored with piston rod moves in cylinder with valve opening

摘要

The shock absorber has a cylinder with a piston rod axially movable which can be stationary and movable against a spring action, linked by a spring and axially adjustably stored. The piston rod moves in a cylinder with valve openings which steer a connection between the positions. The spring forms a valve having a washer, where a second piston (13) has a guide sleeve (31), on the piston rod and the spring which is supported. The limits relative to the guide sleeve (31) are adjustably stored and the maximum spring action of the spring is smaller than the spring action of the spring against the axially adjustable piston.
