Abstract
An engine mount assembly includes a housing, an inertia track received in the housing and an elongated fluid damped first path that is adapted to communicate with an associated first fluid chamber on a first side and an associated second fluid chamber on a second side. A non-damped second path is adapted to communicate with the associated first and second fluid chambers. A decoupler is received in the housing, an idle diaphragm in the housing that selectively controls communication between the first and second fluid chambers to selectively alter the damping. First and second ports in the housing communicate with the decoupler and the idle diaphragm, respectively. A first solenoid selectively controls fluid flow through the first port and a second solenoid selectively controls fluid flow through the second port.
