Abstract

The venting channel (3) that serves the working vol. (2) of the cylinder (1) is connected to atmos. through a constriction nozzle (4) with a buffer vol. (6) inserted into the air line (5) behind an electromagnetically actuated two/two-way valve (8). The venting connection (9) controlled by this valve (8) is closed at speeds below about 5 km/h. The connection (9) is opened at higher speeds with the air line (5) to the buffer vol. (6) and nozzle (4) closed. ADVANTAGE - Can be operated easily, quickly and without jerking even in fault conditions and in starting phase of vehicle.
