Abstract
A hydraulic mount useful for automotive vehicle powertrain applications includes an elastomeric body, a base, a flexible diaphragm and a partition assembled to provide a pumping chamber and a reservoir. An actuator is mounted for moving a closure member between positions to allow flow of fluid between the pumping chamber and the reservoir and to restrict flow of fluid between the pumping chamber and the reservoir. The partition comprises an orifice plate assembly including a valve housing and an annular recess formed in one of two orifice plates for receiving a decoupler. The orifice plates include openings therein for communicating fluid between the decoupler and the pumping chamber and between the decoupler and the reservoir, respectively.
