Abstract
A hydraulic mount is construded as a pair of mounting members, an elastomeric body that connects these members, an elastomeric diaphragm that is connected to one of the members and cooperates with the elastomeric body to define a closed cavity, and a partition that divides the cavity into a chamber enclosed by one side of the partition and the elastomeric body and another chamber enclosed by the other side of the partition and the diaphragm. A cylindrical sleeve interconnects the elastomeric body and one of the mounting members and sealingly peripherally clamps the diaphragm to the one mounting member independent of the partition which is mounted for unrestrained reciprocal movement and solely separates the chambers. A liquid fills the chambers and a damping orifice connects the chambers to provide damping. The damping orifice is provided by forming the partition with a spiral groove in an annular surface thereof that cooperates with an interior wall on the one mounting member to define the damping orifice.
