  • Fluid-sealed engine mounting
    Patent number: 4709898
    Abstract: A fluid-sealed engine mounting has a connector adapted to be connected to an engine, a base adapted to be connected to a vehicle frame, an elastic member joined between the connector and the base and elastically deformable in response to vibrations transmitted thereto, the connector, the base, and the elastic member jointly defining a fluid chamber in which a fluid is sealed, and a partition dividing the fluid chamber into a first chamber adjacent to the connector and a second chamber adjacent to the base, the partition having an orifice through which the first and second chambers communicate with each other. The engine mounting also includes a diaphragm mounted on the base or the connector for varying the volume of one of the first and second chambers when vibrations are transmitted to the engine mounting.
