ABSTRACT:
A hydraulic mount assembly includes a pair of mounting members connected together through a hollow elastomeric body. This hollow body is closed by a resilient diaphragm so as to form a cavity for a damping liquid. A partition divides the cavity into a primary chamber formed between the partition and the hollow body and a secondary chamber formed between the partition and the diaphragm. The partition also includes a bypass track, a damping orifice track and a decoupler passage for providing fluid communication between the cambers. A decoupler is held for limited reciprocating movement in the decoupler opening. An actuator is provided for selectively releasing/disabling the decoupler and opening/closing the bypass track. In a first operative position, the actuator closes the bypass track and allows the decoupler to reciprocate. In a second operative position the actuator engages and disables the decoupler, seals the decoupler opening, and opens the bypass track. In a third operative position the actuator releases the decoupler to allow free reciprocating movement and the bypass track remains open.
