Abstract
A hydraulic two-chamber bearing for damping vibrations, in particular an engine mount on motor vehicles, having an engine-mount plate, a bearing spring made of rubber-elastic material, a working chamber and a compensation chamber for the liquid which are separated from each other by a partition provided with flow-through openings, and an elastic pressure diaphragm which terminates the compensation chamber, characterized in that the amount of fluid flowing through the openings (6) of the partition (5) is controlled as a function of the amplitude (A) of the vibrations.

A hydraulic two-chamber bearing for damping vibrations, comprising:
- an engine-mount plate;
- a bearing spring made of rubber-elastic material;
- a working chamber and a compensation chamber for a fluid which are separated from each other by a partition provided with flow-through openings;
- and
- an elastic pressure diaphragm which terminates the compensation chamber, wherein the amount of fluid flowing through the flow-through openings of the partition is adjustably controlled during operation as a function of the amplitude of the vibrations.
