摘要： A fluid-filled cylindrical elastic mount having an inner sleeve and an outer sleeve, and an elastic body interposed therebetween. The elastic mount also has a primary fluid chamber adapted to undergo pressure changes upon application of a vibrational load to the mount, and a first and a second auxiliary fluid chamber partially defined by a first and a second flexible diaphragm, respectively. The second flexible diaphragm has a greater stiffness than the first flexible diaphragm. A non-compressible fluid flows between the primary and first auxiliary fluid chambers, through a first orifice passage tuned to a first frequency range, and a second orifice passage tuned to a second frequency range that is higher than the first frequency range. The fluid also flows between the primary and second auxiliary fluid chambers, through a third orifice passage tuned to a third frequency range that is higher than the second frequency range. The elastic mount further includes a valve for selectively permitting or interrupting flow of the fluid through the second orifice passage between the primary fluid chamber and the first auxiliary fluid chamber.

摘要： A fluid-filled mount having first and second elastic bodies which elastically connect an inner and an outer sleeve and partially define a pressure-receiving chamber which communicates with a variable-volume equilibrium chamber through an orifice passage. The first elastic body includes two radial portions extending from diametrically opposite circumferential portions of the inner sleeve, in respective radial directions almost perpendicular to a diametric direction in which a static load acts on the mount. A connecting member extends from the inner sleeve between the above two radial portions and which is located on one of diametrically opposite sides of the inner sleeve on which the radial distance between the two sleeves is reduced by the static load. The second elastic body includes two thin-walled lateral walls which extend from respective axially opposite ends of the connecting member and which are inclined in a radially outward direction of the mount, and further includes two thick-walled radial walls which extend from the ends of the lateral walls in the above diametric direction.
摘要翻译：具有第一和第二弹性体的流体填充座，其弹性地连接内套管和外套管，并且部分地限定通过孔口通道与可变容积平衡室连通的压力接收室。第一弹性体包括两个径向部分，其从内套筒的沿径向相对的周向部分延伸，在相应的径向方向上几乎垂直于固定载荷作用在支座上的直径方向。连接构件从内套筒在上述两个径向部分之间延伸，并且位于内套筒的径向相对侧中的一个上，两个套筒之间的径向距离由静载荷减小。第二弹性体包括从连接构件的相应轴向相对端部延伸的两个薄壁侧壁，它们在安装件的径向向外的方向上倾斜，并且还包括两个厚壁的径向壁，其从侧壁在上述直径方向。
