PURPOSE:To achieve wide range damping by providing a gas-tight chamber for absorbing the high frequency low amplitude vibration between liquid separation chambers. CONSTITUTION:An airtight chamber unit 28 for forming an enclosed chamber is arranged between the liquid chambers 26A, 26B to form an inner air chamber with upper and lower resilient rubber films 46, 48. Displacement of each film 46, 48 is limited by a displacement limiting means in the air chamber. Under high frequency low amplitude vibration, pressure rise is prevented through variation of volume of said film 46, 48 while under low frequency high amplitude vibration the displacement of said film is limited to provide the vibration isolating effect through damping function of orifice arranged in a path communicating between the liquid chambers 26A, 26B. |
