ABSTRACT:
A hydraulic-elastomeric mount has a pair of liquid filled chambers formed by elastomeric walls and separated by a rigid partition having an orifice that connects the chambers to effect damping. The partition supports a rigid damping decoupler for free reciprocal movement between oppositely facing rigid sides of the partition so as to effect cyclic volume change in the chambers to eliminate damping under certain conditions. A tapered elastomeric cushion is added to the decoupler to both cushion and cause rocking of same to prevent noise thereby.
