Abstract: An engine mount with hydraulic damping for motor vehicles, which has at least two chambers, which are provided with at least partially elastically deformable walls in a housing and are filled with a damping fluid, and a common wall of the chambers with a valve plate, in which a cage with a decoupling diaphragm made of an elastically deformable material arranged in it is provided. This decoupling diaphragm includes a round disk with constant cross section and is arranged in the cage without axial clearance, at right angles to the common chamber. The openings of the cage have a cross section tapering in the outward direction from the decoupling diaphragm due to oblique limiting surfaces.

Abstract: A sleeve rubber spring for mounts in a motor vehicle, in which a rubber body is arranged between an inner tube and an outer tube and has at least two chambers, which are filled with a fluid damping agent and are connected to one another through at least one overflow channel. A shutoff structure is provided including an axially extending seal, which opens only in the case of a predetermined pressure difference in the chambers. This seal of the shutoff structure of the overflow channel includes at least two sealing lips, which are separated from one another, have a hook-type profile in their cross section with a radial undercut and are deformable radially to the central axis of the sleeve rubber spring.

Abstract: The sleeve rubber spring consists of an inner mounting sleeve (1), an outer mounting sleeve (2) surrounding the inner mounting sleeve at a radially spaced location, and a rubber body (3) arranged rigidly adhering between the two mounting sleeves. The rubber body forms at least two chambers (5, 6) are formed, which are filled with damping medium and permanently communicate with each other. An elastically deformable body forms a protective tube (4), into which the inner and outer mounting sleeves (2) are sealingly inserted. An overflow channel (8) with a shut-off device, which opens automatically at a predetermined pressure differential in the two chambers (5, 6) by radial deformation of the protective tube (4), is provided between the chambers (5, 6).

Abstract: An engine mount with hydraulic damping includes a wall of elastomeric material and a bearing plate for supporting an engine together defining a working chamber. The bearing plate is disposed at an end of the working chamber defining an inner surface of the bearing plate facing the working chamber. The inner surface has a recess formed therein in the form of an air storage chamber. A throttle element closes off the air storage chamber from the working chamber. The throttle element has a central throttle opening formed therein.
