Abstract

A hydraulic engine mount is provided, the dynamic characteristics of which may be varied in response to engine performance parameters. In particular, the invention provides for a hydraulic engine mount comprising a core for attachment to an engine and the base for mounting to a frame, the core and the base being connected to each other by an elastic member, at least two fluid filled and elastically deformable chambers divided by a diaphragm, a throttle for permitting a limited exchange of fluid between the chambers, an absorptive mass selectively movable by the core, and a selectively operable connection between the core and the absorptive mass.
