ABSTRACT:
A fluid-filled elastic mount for flexible coupling of two members, including first support device and second support device, an elastic body, a closure member for partially defining a fluid chamber, a partition device for dividing the fluid chamber into a pressure-receiving and an equilibrium chamber, a restricted passage for restricted fluid communication between the pressure-receiving and equilibrium chambers, an operating device disposed within the pressure-receiving chamber, and an intermediate cylindrical member for connecting the elastic body and the second support member. The cylindrical member has at least one inward flange extending radially inwardly of the engine mount, which cooperates with a surface of the operating device to constitute a first stopper device for limiting a relative displacement between the first and second support devices in one of opposite load-receiving directions, and at least one outward flange extending radially outwardly of the engine mount, which cooperates with a surface of the first support device to constitute a second stopper device for limiting a relative displacement between the first and second support devices in the other load-receiving direction. Each of the first and second stopper devices includes at least one rubber layer formed as part of the elastic body.
