ABSTRACT:
A hydraulic-elastomeric mount is disclosed having a hydraulic damping decoupler mounted for reciprocal movement in a partition in response to alternating pressure buildup in two orifice connected chambers so as to effect cyclic volume change in the chambers to thereby permit vibratory amplitudes below a prescribed level without forcing liquid through the orifice and thus without hydraulic damping thereby and while also providing for limited flow through the partition between the chambers in bypass relation to the orifice so as to effect limited damping during decoupler operation and smooth transition between damping and no damping by the orifice.
