WORK POCKET FOR A HYDRAULIC SHOCK SHOCK ABSORBER.

摘要

Working piston (1) for a hydraulic shock absorber arranged at the end of a piston rod (3), which penetrates with a reciprocating motion into a shock absorber tube (2) filled with damping liquid and subdivides it into two working chambers (4, 5) and having a main body (10) with passage channels (6, 7), which can be closed each at one end by means of back valves built with saucer springs, at at the same time, that the prestressing of the saucer springs or saucer spring packs (8, 9) can be adjusted independently of each other for the compression phase and the traction phase by means of pressure devices, characterized in that the saucer springs or packages (8, 9) of saucer springs seat directly and centrally in the main body (10) and that the prestressing adjustment takes place by elastic and / or plastic deformation of the main body (10) in the surface seat.
