PURPOSE:To damp the vibration of loss factor frequency which is different from orifice to orifice effectively by providing diaphragm chambers dedicated for respective orifices. CONSTITUTION:The low frequency components in the vibration of a power unit are damped by means of the first and second diaphragm chambers 31, 32 while the high frequency components are damped by the function of a rubber member 24. In other word, the low frequency components are damped by the vibration to be produced when the working liquid in a liquid chamber 25 moved through the first and second orifices 34, 35 between the liquid chamber 25 and the first and second diaphragm chambers 31, 32 as the rubber member 24 deforms. Consequently, the vibration of loss factor frequency which is different from orifice to orifice can be damped. |
