Abstract
A hydraulic mounting device for resiliently supporting an engine on a frame includes a support bracket for attachment to a vehicle frame and a cord insert for attachment to an engine. A first chamber and second chamber is formed therein. A partition separates the first and second chamber. The partition includes a first aperture to allow fluid flow between the first and second chamber. The partition also includes a third chamber formed between the first and second chamber and a second aperture in the third chamber to allow fluid flow between the first and second and third chamber. The third chamber includes a plugh disposed therein for floating in the third chamber and for opening the second aperture in response to high frequency and low amplitude engine movements to allow fluid flow through the second aperture between the first and second chambers and for closing the second aperture in response to low frequency and high amplitude engine movements to prevent fluid flow through the second aperture to allow fluid flow between the first and second chambers solely through the first aperture.
