Abstract

PURPOSE:To decrease and absorb vibration of each low and high frequency by slidably providing a partition member having a throttle hole 51, in a connecting path between both fluid chambers so as to convert a pressure difference between both chambers caused by vibration into a flow resistance. CONSTITUTION:A partition member 5 having a throttle hole 51 is slidably mounted in a pipeline between both fluid chambers 1, 2 to which vibration of each low and high frequency is transmitted through engine supporting means 3. When vibration of low frequency and high amplitude occurs, the top wall 13 of a rubber elastic body is elastically deformed, and the capacity of a fluid chamber 1 is changed to cause a pressure difference in sealed-in fluid between the fluid chambers 1, 2, whereby the partition member 5 descends in an instant, fluid in the fluid chamber 2 flows into the fluid chamber 1 through the throttle hole 51 and the vibration is decreased by viscosity resistance in the throttle hole 51. In case of vibration of high frequency and low amplitude, the partition member 5 is vertically reciprocatd by a change in fluid pressure of the fluid chambers 1, 2 to absorb pressure in the fluid chamber 1 and absorb vibration.
