Hydraulic oscillation damper, in particular for stabilising the joint on articulated buses

摘要

Arranged in this hydraulic oscillation damper, in a throughflow passage (3) of the working piston (1), which can be moved backwards and forwards, is a blocking valve, the spring-loaded valve element (7) of which assumes a shut-off position as a function of the flow rate of the damping fluid. In order to adapt the critical flow rate at which the valve should close to the changes in temperature, the valve is fitted with at least one thermostatic bimetal cup spring (14). IMAGE
