Fluid-filled vibration damping device having pneumatically oscillated members partially defining primary and auxiliary fluid chambers

摘要

A fluid-filled vibration damping device wherein two mutually spaced-apart mounting member are elastically connected by an elastic body, which cooperates with a first movable member to define a primary fluid chamber communicating through an orifice with an auxiliary fluid chamber partially defined by a second movable member, and the first and second movable members partially define respective mutually independent first and second working air chambers on their sides remote from the primary and auxiliary fluid chambers, and are oscillated by periodic change of air pressures in the working air chambers.
