ABSTRACT:
A hydraulic-elastomeric vehicle engine mount basically comprising a pair of rigid mounting members, a hollow elastomeric body connecting the members, an elastomeric diaphragm cooperating with the body to form a closed cavity that is filled with a liquid, a partition dividing the cavity into a chamber enclosed by the body and a chamber enclosed by the diaphragm, a damping orifice connecting the chambers so as to provide hydraulic damping as one mounting member is forced to vibrate relative to the other in opposite directions, and a damping decoupler mounted for limited movement on the partition so as to effect cyclic volume change in the chambers and thereby permit vibratory amplitudes without hydraulic damping. To this arrangement is added a secondary orifice through the partition for connecting the chambers, and a jounce-rebound valve movable with the decoupler for opening and closing the secondary orifice so as to effect a reduction in the hydraulic damping in one of the force directions as compared with that in the other force direction during the damping decoupler operation.
