Abstract

Two-chamber motor mount with hydraulic damping, especially for vehicles, including an upper and lower chamber having rubber-elastic walls and being filled with liquid, the upper chamber being of hollow conical construction, a holding flange disposed between the walls of the upper and lower chambers, an intermediate plate formed with a throttle orifice located in vicinity of the holding flange, the upper and the lower chambers being connected to one another through the intermediate plate with the throttle orifice for preventing an hydraulic response for high frequency vibrations of small amplitude, the intermediate plate being responsive to high frequency vibrations of small amplitude and the throttle orifice being automatically closeable at high pressures.
