Abstract
The present invention relates to a hydraulically damped powertrain mount (10) which includes an inner and outer in-series elastomeric springs (12, 14), having a cylindrical form with an oval cross section. The powertrain mount is secured to a supporting object by a flange extending outwardly from the periphery of an outer support housing (18) conforming generally to the shape of the outer elastomeric spring. Adjoining the inner and outer springs is a intermediate metal plate (16) utilized to assemble the springs concentrically in a partially nested relation therewith. A mounting member (22) is received within a centrally located recess portion formed in the inner spring and projects freely from the inner spring for attaching the engine or motor which is to be supported. A diaphragm (32) is secured to the intermediate metal plate and cooperates with the inner spring to define a fluid filled chamber. The fluid chamber is divided by a partition assembly (28) into two fluid filled holding chambers (A, B). The holding chambers communicate with one another through a fluid track (40) within the partition assembly. Fitted within the partition assembly is a decoupler (38) for controlling fl…
