HYDRAULIC-ELASTOMERIC MOUNT Abstract of the Disclosure There is disclosed a hydraulic-elastomeric mount comprising a pair of mounting members that are interconnected by a hollow elastomeric body, an elastomeric diaphragm that closes the elastomeric body to form a closed cavity filled with liquid and a plastic partition and orifice assembly that divides the cavity into a chamber enclosed by the elastomeric body and a chamber enclosed by the diaphragm. The partition and orifice assembly comprises a partition plate that actually separates the chambers and an annular plate having mating faces formed so as to cooperatively define at least one orifice between the plates extending in a plane along and adjacent the periphery of the plates with each of the plates further having an opening there- through to one end only of the orifice so that it interconnects the chambers and has a length which may thereby be made substantially as expansive as the periphery of the plates. There is also a two- piece plastic damping decoupler assembly that fits together through and has a limited travel connection with the partition plate so as to effect limited cyclic volume change in the chambers and thereby permit limited vibratory amplitudes at low frequencies without hydraulic damping.
