<p>An electronically switchable bi-state engine mount includes a housing having an inertia track received in the housing between first and second fluid chambers. A fluid damped first path communicates between the chambers, and a non-damped second path or bypass opening also communicates between the chambers. A diaphragm encloses a portion of the second fluid chamber and a seal member on the diaphragm operatively cooperates with a solenoid plunger, where the solenoid is received in the housing to selectively open and close the second path. The diaphragm is enclosed by a cover, which is preferably metal, to enhance thermal conductivity and heat sink properties thereof and improve the useful life of the solenoid.</p> |
