摘要： A fluid-filled elastic mount is disclosed which includes a first and a second support member, an elastic body for interconnecting the support members and partially defining a pressure-receiving chamber, and a partition structure which cooperates with a first and a second flexible diaphragm to define a first and a second equilibrium chamber. The elastic mount has a first and a second orifice passage for fluid communication between the pressure-receiving chamber and the respective equilibrium chambers. The elastic mount further has an air chamber on one side of the second diaphragm remote from the second equilibrium chamber, and an operating chamber separated from the air chamber by a biasing elastic member. The operating chamber is subjected to a vacuum pressure as needed to move the second diaphragm away from the opening of the second orifice passage, which is normally closed by the second diaphragm due to a biasing force of the biasing elastic member. The elastic mount further includes a rigid planar member interposed between a top plate of the biasing elastic member and the second diaphragm. Between the rigid planar member and the top plate of the biasing elastic member is formed an air passage for permitting an air flow into a central portion of abutting faces thereof upon abutting contact therebetween.

摘要： A fluid-filled elastic mount including first and second support members and an elastic body interposed between these support members for elastically 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, and a vacuum-receiving chamber which is separated by the second diaphragm from the second equilibrium chamber. In operation, the vacuum-receiving chamber is selectively subjected to a sub-atmospheric pressure or exposed to the atmosphere to control the elastic deformation of the second diaphragm. The elastic mount further has an auxiliary air chamber which cooperates with the vacuum-receiving chamber to accommodate a volumetric change of the second equilibrium chamber when the vacuum-receiving chamber is exposed to the atmosphere.

摘要： A fluid-filled elastic mount including mutually spaced-apart first and second support members, and an elastic body for elastically connecting the first and second support members. The elastic mount has a plurality of fluid chambers filled with a non-compressible fluid and communicating with each other through an orifice passage or passages, and an air-tight operating chamber which is formed on one side of a flexible membrane remote from the corresponding fluid chamber. This flexible membrane consists of a fluid-impermeable first flexible layer which is corrosion-resistant to the non-compressible fluid, and a fluid-impermeable second flexible layer which is corrosion-resistant to gasoline. These flexible layers are superposed on each other such that the first flexible layer is exposed to the fluid chamber while the second flexible layer is exposed to the operating chamber. The elastic mount further includes a pressure control device for applying a vacuum pressure to the operating chamber so as to restrict elastic deformation of the flexible membrane.

摘要： A fluid-filled elastic mount including an elastic body interposed between an inner and an outer sleeve, a pressure-receiving chamber disposed between the two sleeves, a first and a second equilibrium chambers partially defined by respective flexible diaphragms for absorbing pressure chambes in the two equilibrium chambers: a first and a second air chamber corresponding to the first and second equilibrium chambers, for permitting elastic deformation of the respective diaphragms; and a first and a second orifice passage for fluid communication between the pressure-receiving and the first and the second equilibrium chambers. The second orifice passage has a ratio of its cross sectional area to its circumferential length, which is higher than that of the first orifice passage. The elastic mount further includes a pressure control device connected to the second air chamber for changing a pressure in the second air chamber. This pressure control device includes a switch device which is operable between a first position for communication of the second air chamber with a first pressure and a second position for communication of the second air chamber with a second pressure higher than the first pressure, so that the fluid flows only through the first orifice passage when the switch device is placed in the first position, and through the second orifice passage when the switch device is placed in the second position.

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 an elastic restriction member which is opposed to the second diaphragm and cooperates with the diaphragm to define a vacuum-receiving chamber for allowing elastic deformation of the second diaphragm. In operation, a vacuum pressure is applied where appropriate to the vacuum-receiving chamber, to draw the second diaphragm onto the elastic restriction member, so as to restrict free deformation of the second diaphragm and permit oscillation of the diaphragm with the elastic restriction member.
