IPC: F16F9/16
Filed: 1989-03-16
Abstract: PURPOSE:To effectively attenuate microvibration by coaxially depositing fixed cylinders and moving cylinders in a closed cylindrical casing in which a viscous fluid is filled. CONSTITUTION:When a mechanical device 1 is worked to generate vertical vibration, the device 1 being supported by a coil spring 6, a buffer is created and the vibration is reduced to microvibration of small amplitude thereby. The vibration of the device 1 is also transmitted to a viscous damper 7.
