Abstract
Abstract A hydraulically damped mounting device has two anchor parts (1,3) joined by a resilient spring wall (9). The resilient spring wall (9) and a partition (6) define a working chamber (13) for liquid, the working chamber (13) being in communication with a compensation chamber (14) via a passage (73,74,75,76). The compensation chamber (14) is bound by a flexible bellows wall (5). A flexible diaphragm (66) of annular shape defines, together with the partition (6), a gas chamber. The annular nature of the diaphragm (66) means that the centre of the partition (6) which bears the most load during relative vibration of the anchor parts can be made strong.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A hydraulically damped mounting device having two anchor parts (1,3) connected by a first deformable wall (9); a working chamber (13) enclosed between the first deformable wall (9) and a rigid partition (6) rigidly associated with a first one (1) of the anchor parts, the working chamber (13) containing liquid; a compensation chamber (14) being at least partially bounded by a second deformable wall (5); a passage (42;73,74,75,76) between the chambers (13,14) to allow fluid communciation of the liquid between them; and a flexible diaphragm (45,66) on the partition (6) in direct contact with the liquid in the working chamber (13), the flexible diaphragm (45,66) acting as a barrier between the liquid and a gas chamber (46); characterised in that: the flexible diaphragm (45,66) is annular.
Claim 2
Dependent Claim
126 words
A hydraulically damped mounting device having two anchor parts (1,3) connected by a first deformable wall (9); a working chamber (13) enclosed between the first deformable wall (9) and a rigid partition (6) rigidly associated with a first one (1) of the anchor parts, the working chamber (13) containing liquid; a compensation chamber (14) being at least partially bounded by a second deformable wall (5); a passage (42;73,74,75,76) between the chambers (13,14) to allow fluid communciation of the liquid between them; and a flexible diaphragm (45,66) on the partition (6) in direct contact with the liquid in the working chamber (13), the flexible diaphragm (45,66) acting as a barrier between the liquid and a gas chamber (46); characterised in that: the flexible diaphragm (45,66) is annular.
Claim 3
Dependent Claim
29 words
A hydraulically damped mounting device according to claim 1, wherein the first deformable wall (9) includes an elastomeric spring and the second deformable wall (5) includes a flexible bellows.
Claim 4
Dependent Claim
