Abstract
A compound engine mount has a first and a second fluid chamber defined thereinside and communicated to each other by a first orifice which is controllable in length and a second orifice which is controllable in effective path area. In an engine idling range, the two fluid chambers are intercommunicated by the first orifice only. The length of the first orifice is controlled to change the mass of a fluid inside of the orifice in response to a length of the orifice, whereby the dynamic spring constant of the engine mount is controlled. In a high engine speed range, the fluid chambers are intercommunicated by the second orifice resulting in a decrease in the dynamic spring constant of the engine mount. The effective area of the second orifice is controllable to control the dynamic spring constant.
