FLUID MOUNT

PROBLEM TO BE SOLVED: To perform effective vibration suppression by decreasing a dynamic spring constant in a high frequency without deteriorating a damping effect in a low frequency. SOLUTION: In a fluid mount interposing an elastic unit 5 between inner/outer cylinders 1, 3, providing a plurality o...

Summary:PROBLEM TO BE SOLVED: To perform effective vibration suppression by decreasing a dynamic spring constant in a high frequency without deteriorating a damping effect in a low frequency. SOLUTION: In a fluid mount interposing an elastic unit 5 between inner/outer cylinders 1, 3, providing a plurality of liquid chambers 7a, 7b, 7c, 7d in a peripheral direction between the inner/outer cylinders, and providing an orifice 9 communicating with the liquid chambers 7a to 7b over between the liquid chambers 7a to 7d also through communication holes 15a to 15h, a flow length of liquid flowing from the liquid chambers 7a to 7d through the orifice 9 is selectively changed a flow of low with high frequency in the orifice 9.
