Title:

LIQUID ENCAPSULATED VIBRATION PREVENTIVE DEVICE

Document Type and Number:

Japanese Patent JPS604640

Kind Code:

A

Abstract:

PURPOSE:To provide proper effect of suppressing or preventing vibration throughout the range of operating condition of a car, by furnishing a throttle hole in a movable plate, which partitions No.1 fluid chamber having bellows as its walls from No.2 fluid chamber having deformable walls, and by controlling motion of the partition plate with a solenoid. CONSTITUTION:Bellows 1 constituting walls of No.1 fluid chamber A expands and contracts in the vertical direction freely without significant resistance, while retaining sufficient rigidity in the horizontal direction. The motion of a movable partition plate 6 installed between No.1 fluid chamber A and No.2 fluid chamber B is restricted by a solenoid 4 attracting a stopper plate 8. Here communication between the fluid chambers A and B is made through a throttle hole F to cause damping of vibrations.
