Two nozzle shock absorber for wheel suspension e.g. of vehicle comprises cylinder barrel and piston forming two work chambers divided by diaphragm forming balancing area for pressure adjustment

摘要

The two nozzle absorber has cylinder barrel (2) mounted with piston (5), which divides it into two work chambers (6,7), and also has a container (3). The balancing space is divided into two subspaces (12,13) by a diaphragm (11), whereby the work chamber connected to one subspace is filled with damping fluid and the other work chamber connected to the second subspace is filled with gas. A balancing space (9) is built between the cylinder barrel and the container, which is connected to one or both the work chambers over a valve. The surface of the diaphragm is provided parallel to the absorber center line (A). The container consists of a lateral bulge (14) which takes up the gas filled subspace.
