Abstract: A hydraulically damped mounting device has a first anchor part; a second anchor part being a hollow sleeve containing the first anchor part, with the first anchor part extending axially of the sleeve; first and second resilient walls interconnecting the first and second anchor parts, two walls being spaced apart to define an enclosed space within the sleeve extending circumferentially around the first anchor part and axially bounded by the resilient walls. First and second deformable walls extend axially between the resilient walls at circumferentially spaced locations, so as to divide the enclosed space into first and second chambers for hydraulic fluid. A passageway interconnects the first and second chambers. The deformable walls have a flap, the movement of which is controlled by support devices so that the flap deforms to allow fluid to pass between the chambers only at or above a predetermined fluid pressure.

Abstract: A hydraulically damped mounting device has a first anchor part; a second anchor part in the form of a hollow sleeve containing the first anchor part, such that the first anchor part extends axially of the sleeve; first and second resilient walls interconnecting the first and second anchor parts, the first and second resilient walls being spaced apart so as to define an enclosed space within the sleeve extending circumferentially around the first anchor part and axially bounded by the first and second resilient walls; first and second deformable walls, each extending axially between the first and second resilient walls at circumferentially spaced locations, so as to divide the enclosed space into first and second chambers for hydraulic fluid; a passageway interconnecting the first and second chambers, the passageway being for flow of hydraulic fluid therethrough.
