Brief Patent Description - Full Patent Description - Patent Application Claims
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] The present invention relates generally to suspension elements for suspending the compressor assembly within the hermetic shell. PCT/NZ2004/000108 describes several suspension arrangements using coil springs. SUMMARY OF THE INVENTION [0004] It is an object of the present invention to provide a suspension element with improved characteristics with particular application to linear compressors and/or to provide refrigeration compressors incorporating such suspension elements, or to at least provide the industry with a useful choice. [0005] In a first aspect the invention consists in a suspension element supporting a linear compressor within a hermetic shell, said suspension element comprising: [0006] a first attachment portion connected to the compressor, a second attachment portion connected to an upper support point above the compressor, and a body spanning between said first attachment portion and said second attachment portion, said body comprising a flexible planar or linear element, oriented perpendicular to the axis of reciprocation of said compressor. [0007] 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 [0008] a first suspension element comprising: [0009] a first attachment portion connected to the compressor, a second attachment portion connected to an upper support point above the compressor, and a body spanning between said first attachment portion and said second attachment portion, said body comprising a flexible planar or linear element, oriented perpendicular to the axis of reciprocation of said compressor; [0010] and a second suspension element comprising: [0011] a first attachment portion connected to the compressor, a second attachment portion connected to an upper support point above the compressor, and a body spanning between said first attachment portion and said second attachment portion, said body comprising a flexible planar or linear element, oriented perpendicular to the axis of reciprocation of said compressor; [0012] the first attachment portion of each said suspension element being connected with said compressor part of greater mass, and the second attachment portion of each said element being fixed to one part of said hermetic housing, such that substantially the entire weight of said compressor hangs from said second attachment portions. [0013] 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 [0014] 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. [0015] FIG. 2 is a perspective view of a suspension element according to a first embodiment of the present invention. [0016] FIG. 3 is a side elevation, with partial cutaway, showing a pair of suspension elements as illustrated in FIG. 2 assembled together. [0017] FIG. 4 is a side elevation of a suspension assembly for one end of the compressor, including a pair of suspension elements assembled together, a clamp for clamping the elements to the compressor and locating components for securing the suspension elements within the compressor housing. The locating components and clamp are shown in cross-section through the centre line of the compressor. The suspension elements are shown in partial cutaway. [0018] FIG. 5 is a perspective view of the clamp illustrated in the assembly of FIG. 4. [0019] FIG. 6 is a perspective view of a locating component in accordance with the assembly of FIG. 4.
