FIELD OF THE INVENTION [0001] The present invention relates to linear compressors, and in particular linear compressors of the type suitable for use in a vapour compression refrigeration system. BACKGROUND TO THE INVENTION [0002] Linear compressors of a type for use in a vapour compression refrigeration system are the subject of many documents in the prior art. One such document is our co-pending PCT patent application PCT/NZ2004/000108. That specification describes a variety of developments relating to compressors, many of which have particular application to linear compressors. The present invention relates to further improvements to compressor embodiments such as are described in that patent application, which provides a general description of an example compressor to which the present invention may be applied. However the present invention may also be applied beyond the scope of the particular embodiments of linear compressor disclosed in that application. Persons skilled in the art will appreciate the general application of the ideas herein to other embodiments of linear compressors such as are found in the prior art. [0003] PCT/NZ2004/000108 describes a number of arrangements for suspending a linear compressor assembly in a hermetic shell using coil springs. [0004] The present invention relates generally to suspension elements for suspending the compressor assembly within the hermetic shell not using coil springs. SUMMARY OF THE INVENTION [0005] It is an object of the present invention to provide a suspension element with improved characteristics with particular application to a linear compressor and/or to provide refrigeration compressors incorporating such elements, or to at least provide the industry with a useful choice. [0006] In a first aspect the invention consists in a suspension element for use in supporting a linear compressor within a hermetic shell, said element comprising: [0007] a hub component adapted for fixing to a first object, [0008] a substantially rigid ring, and [0009] an elastic membrane extending across the area of said ring and secured to said ring around its periphery, [0010] said hub component being secured to said membrane at the centre of said ring. [0011] According to a further aspect said membrane is moulded over said ring, and is moulded over at least a part of said hub component. [0012] According to a further aspect said membrane comprises a natural or artificial rubber, polyurethane material, or rubber substitute. [0013] In a further aspect the present invention consists in a refrigeration system compressor comprising a hermetic housing, a linear compressor within said hermetic housing, said compressor including at least two relatively reciprocating parts, with one part typically being much greater mass than the other part, the relative reciprocation of the centre of mass of each part occurring along an axis of reciprocation, and [0014] at least a pair of suspension elements substantially as set forth in one or more of the above paragraphs, the hub portion of each said suspension element being connected with said compressor part of greater mass, such that the centre of said hub at least substantially coincides with said axis of reciprocation, and the ring portion of each said element being fixed to at least one part of said hermetic housing. [0015] To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the scope of the invention as defined in the appended claims. The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting. BRIEF DESCRIPTION OF THE DRAWINGS [0016] FIG. 1 is a side elevation in cross-section of a refrigeration compressor including a linear compressor suspended in a housing. The compressor is suspended in the housing at each end by a suspension element according to a preferred embodiment of the present invention. [0017] FIG. 2 is a perspective view of a suspension element according to a first embodiment of the present invention. [0018] FIG. 3 is a perspective view of a suspension element according to a variation of the invention where the membrane does not cover the entire area bounded by the ring. DETAILED DESCRIPTION [0019] Referring to FIG. 1, the compressor for a vapour compression refrigeration system includes a linear compressor 1 supported inside a housing 2. Typically the housing 2 is hermetically sealed and includes a gases inlet port 3 and a compressed gases outlet port 4. Uncompressed gases flow within the interior of the housing surrounding the compressor 1. These uncompressed gases are drawn into the compressor during intake stroke, compressed between the piston crown 14 and valve plate 5 on the compression stroke, and expelled through discharge valve 6 into a compressed gases manifold 7. Compressed gases exit the manifold 7 to the outlet port 4 in the shell through a flexible tube 8. To reduce the stiffness effect of discharge tube 8 the tube is preferably arranged as a loop or spiral transverse to the reciprocating axis of the compressor. The intake to the compression space may be through the piston (with an aperture and valve in the crown) or through the head, divided to include suction and discharge manifolds and valves.
