ABSTRACT:
A hydraulically damped resilient mounting. Compared to undamped mountings, motor mounts having hydraulic damping transmit more noise because the damping device that is desirable for driving comfort favors the transmission of noise. The inventive damping device can be selectively activated or deactivated as needed by shifting the damping fluid, which is moved as a single incompressible body. For this purpose, the damping fluid is accommodated between two flexible diaphragms that are subjected to pressure differentials which are produced randomly or are controlled by a computer.
