Abstract

A hydraulic engine mount comprising two fluid-filled chambers normally communicating with each other to affect a controlled throttled exchange of fluid between them sufficient to absorb relative movements of high frequency low amplitude between an engine and a chassis. Relative movements of high amplitude and low frequency may be absorbed by rendering the mount soft by opening a bypass to provide for a substantially unimpeded flow of fluid between the chambers. Preferably, the bypass is provided with valve means controlled by sensors reacting to parameters representing engine performance or the like.
