ABSTRACT:
A liquid-encapsulated anti-vibration device is provided having an inner shell and an outer shell connected to each other by means of a first elastomeric member, a second elastomeric member and a diaphragm. A main liquid chamber is defined between the first and second elastomeric members and changed in volume by the axial movement of the inner and outer shells relative to each other. A subsidiary liquid chamber is defined between the first elastomeric member and the diaphragm. The main and subsidiary liquid chambers communicate with each other by a constriction extending axially through the first elastomeric member. Since the diaphragm is mounted independently from the first elastomeric member, the size and shape of the constriction, defined in the first elastomeric member, cannot be limited by the diaphragm. Thus, it is ensured that the constriction has a sufficient length to permit communication between the main liquid chamber and the subsidiary liquid chamber in the liquid-encapsulated anti-vibration device to decrease the resonant frequency without decreasing the cross-sectional area of a flow path in the constriction.
