Abstract
A vibration-absorbing mount with hydraulic damping, especially for mounting an internal-combustion engine upon a vehicle chassis, comprises a housing subdivided internally by an elastic wall which is connected with the force-transmitting member of the mount and is formed with an orifice enabling fluid to pass between the two chambers. For small pressure differentials, the pressure equalization between the two chambers is effected substantially by transfer of fluid through the orifice while large pressure differentials, representing high frequency oscillations, are damped primarily by deformation of the movable wall.
