Fluid-filled elastic mount having vacuum-receiving chamber partially defined by elastic member for isolating high-frequency vibrations

摘要: A fluid-filled elastic mount including first and second support members an body interposed between these for connection thereof. The has a pressure-receiving chamber partially defined by the body, equilibrium chambers flexible diaphragms communicating with through orifice passages, respectively. passage higher ratio of cross sectional area to length than passage. present further includes restriction member which is opposed diaphragm cooperates define vacuum-receiving allowing deformation diaphragm. In operation, vacuum pressure applied where appropriate chamber, draw onto member, so as restrict free permit oscillation member.
