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.

Engine mount with hydraulic damping

A two chamber engine mount with hydraulic damping includes rubber-elastic peripheral walls, a support housing disposed outside at least one of the walls, an orifice plate disposed between the walls defining upper and lower fluid-filled chambers above and below the orifice plate being substantially horizontally divided into an upper plate half being stationary and a lower plate half being rotatable and having a central axis, the orifice plate having an orifice canal formed at least partly in the lower plate half interconnecting the chambers and having a given open length and cross section, a centrally disposed pin integral with the lower plate half and extending through the support housing for rotating the lower plate half about the central axis relative to the upper plate half, varying at least one of the length and cross section of the canal.
