Title:
LIQUID SEALED VIBRATION ISOLATING DEVICE
Document Type and Number:
Japanese Patent JPS608539
Kind Code:
A
Abstract:
PURPOSE:To obtain an appropriate vibration suppressing and isolating effect in the whole operating area by forming the wall part of a fluid chamber which is deformed by vibration, with bellows while making a partition board movable on which a throttle hole for allowing a sealed fluid to flow is provided. CONSTITUTION:A top board 2 is provided on the top side opening of bellows 1 while its bottom side opening is connected to a flange member 3. A side board 4 is provided under the flange member 3 and an elastic-body sheet 5 is provided inside the side board 4 in such a way that the sheet 5 partitions the inside into upper and lower parts. A movable partition board 6 is provided on the bottom side opening, and fluid chambers A, B are formed above and below this movable partition board 6 respectively, while a half annular member 7 is joined to the top surface of the movable partition board 6. A through hole 71 formed by the movable partition board 6 and the half annular member 7 is connected to each of vent holes 72, forming a throttle hole F between both fluid chambers A, B. Thereby an appropriate vibration suppressing and isolating effect can be obtained by means of the expanding and contracting action of the bellows 1 and the throttling action of the throttle hole F.
