ABSTRACT:
A hydraulic mount has a pair of mounting members, an elastomeric body that connects the mounting members, an elastomeric diaphragm that is connected to one of the members and cooperates with the body to define a closed cavity, and a partition that divides the cavity into a chamber enclosed on one side by the partition and the elastomeric body and another chamber that is enclosed on one side by the partition and the diaphragm. A liquid fills the chambers and a damping orifice connects the chamber to provide damping by throttling liquid flow therethrough. The partition comprises a rigid singular imperforate body that is mounted at a cylindrical surface thereof for unrestrained reciprocal movement within prescribed limits in an interior cylindrical wall of one of the mounting members thereby to effect limited cyclic volume change in the chambers so that the liquid is not then forced through the damping orifice.
