Fluid-filled elastic mount having vacuum-receiving chamber partially defined by flexible diaphragm with rigid restriction member |
摘要 |
A fluid-filled elastic mount including first and second support members and an elastic body interposed between these members for elastic connection thereof. The elastic mount has a pressure-receiving chamber partially defined by the elastic body, first and second equilibrium chambers defined by first and second flexible diaphragms and communicating with the pressure-receiving chamber through first and second orifice passages, respectively. The second orifice passage has a higher ratio of the cross sectional area to the length than the first orifice passage. The present elastic mount further includes a pressure control device for selectively applying a vacuum pressure to a vacuum-receiving chamber which lies behind the second equilibrium chamber via the second diaphragm, to thereby restrict elastic deformation of the second diaphragm. A rigid restriction member is secured to a part of the second diaphragm which is opposed to an opening of an air passage through which the vacuum pressure is applied to the vacuum-receiving chamber.
