Vibration absorbing apparatus

Abstract

Abstract PURPOSE:To provide a vibration absorbing apparatus, capable of absorbing vibrations inclusive of high-frequency vibrations, by providing a plate member formed with many apertures in a fluid in a tank, and also providing a rod connected to the plate member in the tank in the manner that it is movable in the direction of the thickness of said plate member. CONSTITUTION:Oil 3 is reserved in a tank 1 and the upper opening of the tank 1 is closed by bellows 4. A rod 5 is extended through the bellows 4 and a plate mem- ber 6 is connected to one end of the rod 5 located on the inside of the tank 1 by use of a spherical joint 7. A spring washer 9 is connected to the other end of the rod 5 located on the outside of tank 1 by use of a spherical joint 8. A coil spring 11 is provided between the spring washer 9 and another spring washer 10. In case that relative vibration is caused in the direction of the thickness of plate member 6 between the tank side and the rod side, fluid in tank 1 is caused to flow through the plate member 6 via many apertures 13, so that the plate member 6 can be moved to follow up vibrations including high-frequency vibrations.
