Abstract
Abstract A resilient mounting (1) comprises main (2) and auxiliary (3) fluid chambers between which a restricted flow of damping fluid can take place in use of the mounting (1). The auxiliary chamber (3) is detected at least in part by a flexible membrane (9) of convoluted profile in the unloaded condition such that fluid displaced from the main chamber (2) is accommodated without stretching the membrane (9). Preferably the membrane (9) is formed in a first profile corresponding to that which it adopts in the static load condition and is deflected to said convoluted profile in the unloaded condition. Preferably the membrane (9) is also convoluted in the first profile so that fluid displaced due to both the static load and dynamic working loads is accommodated without stretching the membrane (9). The avoidance of tensile stresses in the membrane (9) improves the fatigue life thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
74 words
A resilient mounting (1) for connecting two components which are movable relative to each other comprises main and auxiliary fluid chambers (2,3) which in use of the mounting (1) contain a damping fluid between which a restricted flow of fluid can take place upon relative movement between said components characterised in that the auxiliary chamber (3) is defined at least in part by a flexible membrane (9) of convoluted profile in the unloaded condition.
Claim 2
Dependent Claim
74 words
A resilient mounting (1) for connecting two components which are movable relative to each other comprises main and auxiliary fluid chambers (2,3) which in use of the mounting (1) contain a damping fluid between which a restricted flow of fluid can take place upon relative movement between said components characterised in that the auxiliary chamber (3) is defined at least in part by a flexible membrane (9) of convoluted profile in the unloaded condition.
Claim 3
Dependent Claim
42 words
A mounting according to Claim 1 characterised in that the membrane (9) is constructed and arranged to accommodate fluid displaced from the main chamber (2) up to a predetermined load, e.g. the static load, without any significant stretching of the membrane (9).
Claim 4
Dependent Claim
42 words
A mounting according to Claim 2 characterised in that the membrane (9) as formed has a profile different to the convoluted profile adopted in the unloaded condition whereby the membrane (9) returns substantially to its as formed profile under said predetermined load.
Claim 5
Dependent Claim
38 words
A mounting according to any one of the preceding claims characterised in that the auxiliary chamber (3) is contained within a rigid inner support member (7) adapted for connection to one of the two components to be connected.
Claim 6
Dependent Claim
72 words
A mounting according to Claim 4 characterised in that the main chamber (2) is defined at least in part by an elastomeric spring (6) which acts between an external surface (7a) of the inner support member (7) and an internal surface (8a) of an outer support member (8) adapted for connection to the other of the two components to be connected, and said internal and external surfaces (7a,8a) are optionally of-frusto-conical profile.
Claim 7
Dependent Claim
31 words
A mounting according to Claim 5 characterised in that the inner and outer support members (7,8), elastomeric spring (6) and membrane (9) are formed as an integral fully bonded unit (18).
Claim 8
Dependent Claim
63 words
A mounting according to any one of the preceding claims characterised in that the main and auxiliary chambers (2,3) are separated by a partition wall (4) constructed and arranged to control the flow of fluid between the chambers (2,3), for example the partition wall (4) may have at least one aperture (5) therein for the passage of damping fluid between the chambers (2,3).
Claim 9
Dependent Claim
36 words
A mounting according to any one of the preceding claims characterised in that means (13) is provided to prevent the fluid displaced from the main chamber (2) to the auxiliary chamber (3) exceeding a predetermined value.
Claim 10
Dependent Claim
121 words
A resilient mounting (1) for connecting two components which are movable relative to each other comprises main and auxiliary fluid chambers'(2,3) which in use of the mounting (1) contain a damping fluid between which a restricted flow of fluid can take place upon relative movement between said components characterised in that the auxiliary chamber (3) is defined at least in part by a flexible membrane (9) which is formed in a first profile corresponding to the profile adopted at a predetermined load condition, e.g. the static load, and is deflected to a second, convoluted profile in the unloaded condition such that in use of the mounting (1) the membrane (9)reverts to its as formed first profile at said predetermined load condition.
Claim 11
Dependent Claim
121 words
A resilient mounting (1) for connecting two components which are movable relative to each other comprises main and auxiliary fluid chambers'(2,3) which in use of the mounting (1) contain a damping fluid between which a restricted flow of fluid can take place upon relative movement between said components characterised in that the auxiliary chamber (3) is defined at least in part by a flexible membrane (9) which is formed in a first profile corresponding to the profile adopted at a predetermined load condition, e.g. the static load, and is deflected to a second, convoluted profile in the unloaded condition such that in use of the mounting (1) the membrane (9)reverts to its as formed first profile at said predetermined load condition.
Claim 12
Dependent Claim
17 words
A mounting according to Claim 9 characterised in that said membrane (9) is formed in convoluted profile.
