PURPOSE:To provide a fluid enclosed mount capable of damping both vibration caused by large load and vibration caused by small load. CONSTITUTION:An elastic body 4 is installed over a supporting member 2 and connecting member 3, and a diaphragm 4 is arranged below the elastic body 4, and a fluid chamber 6 is formed between the elastic body 4 and the diaphragm 5. Ethylene glycol 8 of low viscosity and high specific gravity and silicon oil 9 of high viscosity and low specific gravity are filled in the fluid chamber 6. A moving plate 3a which moves in the fluid chamber 6 when a load works is connected to the connecting member 3 and is soaked in the silicon oil 9 while loads do not work. When a large load works, the load is damped by the high viscous silicon oil 9, and when a small load works and vibration is generated, the vibration is damped by the low viscous ethylene glycol 8. |
