PURPOSE: To provide a liquid sealed type vibration control device for reducing explosion vibration of an engine effectively. CONSTITUTION: A main liquid chamber A making a rubber elastic member 1 as a wall the volume of which is changed by vibration inputted from an engine and an auxiliary liquid chamber B making a rubber elastic member film 3 as its wall which is divided from the main liquid chamber A by a diaphragm 2 are provided in a device and an orifice 21 communicating with the main liquid chamber A and the auxiliary liquid chamber B is mounted in the diaphragm 2 to reduce vibration by action of the liquid running through the orifice 21. A pressure chamber 26 communicating with the main liquid chamber A and an orifice piston 22 moving according to change of internal pressure are mounted in the diaphragm 2 and opening degree of the orifice is increased accompanying the rise of change in the internal pressure in the pressure chamber 26. |
