Fluid-filled power unit mount device

摘要

A fluid-filled power unit mount device consists of a mount rubber securely interposed between two base plates. A partition plate is securely connected to one of the base plate so as to define fluid and auxiliary chambers on the opposite sides thereof. The partition plate is formed with an orifice to provide fluid communication between the fluid and auxiliary chambers, and provided with two parallely arranged movable mechanisms each having a movable member. The movable member is movable under small amplitude high frequency vibration causing booming noise, but restrained from its movement under large amplitude low frequency vibration, thereby effectively damping even vibration which is slightly higher in frequency than the booming noise generating high frequency vibration.
