Definitions

  • Figure 1 is a plan elevation in cross-section of a linear compressor according to a first embodiment.
  • the first embodiment has a main spring comprising a combination of a flat spring and a coil spring.
  • the flat motor armature is radially supported at one end by the main spring and at the other end by the piston.
  • Figure 1 is a cross-section taken through line DD of Figure
  • Figure 6 is a side elevation in cross-section of the embodiment of Figure 5, taken through line AA of Figure 5.
  • 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.
  • the illustrated compressors have suction through the head, with suction manifold 13 and suction valve 29.
  • the illustrated linear compressor 1 has, broadly speaking, a cylinder part and a piston part connected by a main spring.
  • the cylinder part includes cylinder housing 10, cylinder head 11, valve plate 5 and a cylinder 12.
  • the cylinder part also includes stator parts 15 for a linear electric motor.
  • An end portion 18 of the cylinder part, distal from the head 11, mounts the main spring relative to the cylinder part.
  • the main spring is formed as a combination of coil spring 19 and flat spring 20.
  • the main spring comprises a stack of a plurality of planar springs 16.
  • the rod 26 has a flexible portion 28, located at approximately the centre of the hollow piston 22.
  • the rod 21 is narrow over its whole length.
  • the linear compressor 1 is mounted within the shell 2 on a plurality of suspension springs to isolate it from the shell.
  • the cylinder part will oscillate along the axis of reciprocation of the piston part within the cylinder part.
  • the piston part is purposely kept very light compared to the cylinder part so that the oscillation of the cylinder part is small compared with the relative reciprocation between the piston part and cylinder part.
  • the linear compressor is mounted on a set of four suspension springs 31 generally positioned around the periphery. Alternate suspension spring arrangements are illustrated in PCT/NZ2004/000108. The ends of each suspension spring fit over elastomeric snubbers connected with the linear compressor 1 at one end of each spring and connected with the compressor shell 2 at the other end of each spring.
  • Figures 3 and 4 and Figures 5 and 6 illustrate a further aspect of the present invention.
  • the piston rod, carrying the armature 17 is supported against lateral loading by the main spring at one end and through the piston at the other end. This is desirable for its compactness and simplicity however it does result in increased side loading of the piston within the cylinder bore. This extra side loading can be managed and examples of how to manage it are given in our patent applications, including in relation to the embodiment of Figures 1 and 2 herein.
  • Figures 3 and 4 and 5 and 6 herein provide an alternative approach to dealing with the lateral forces resulting from the flat permanent magnet linear motor, where the motor is located on the member connecting between the main spring and the piston.
  • a radial or lateral support is provided to act between the cylinder part 1 and the connecting member at a location between the armature magnets and the piston. The support transmits the side loads from the connecting member directly to the cylinder part 10.
  • an open frame construction such as illustrated in Figures 4 and 5 is used to support the lateral support (e.g. planar spring or sliding bearing) relative to the cylinder part 10.
  • a plurality of windows or apertures such as openings 56 in Figures 5 and 6 may be provided which communicate both with the region of the cylinder part housing the linear electric motor and with the region of the cylinder part housing the cylinder and piston.
  • This gases flow capability into the inside of the cylinder part 10 is also useful to reduce any gas pressure effects on the back face of the piston 22 and to provide gas flow paths to the back face of piston 22 in embodiments where suction gases flow is provided through the crown of the piston rather than through the compressor head.
  • a preferred connection between the armature supporting member 30 and the piston 22 has considerable lateral compliancy while retaining axial stiffness.
  • a suitable linkage would include a narrow metal rod embedded at one end in the end of the armature supporting member 30 and at the other end in the piston crown 14.
  • the thin rod 21 should have sufficient compliancy to allow the orientation of piston 22 to adapt to any misalignment between the armature support member 30 and the cylinder 12, and sufficient axial stiffness that it will not buckle as the linear motor and springs drive the piston toward the cylinder head during the compression stroke of the compressor in operation.

Abstract

Compresseur linéaire comprenant un élément cylindre à alésage cylindrique. Un piston est logé dans l'alésage, dans lequel il coulisse. Un ressort principal relie directement ou indirectement l'élément cylindre au piston. Un élément de liaison relie le ressort principal et le piston. Un stator présente un entrefer que traverse l'élément de liaison. Un ou plusieurs blocs sensiblement plats d'aimant permanent sont fixés à l'élément de liaison, les faces de grandes dimensions étant tournées vers le stator. Le matériau des aimants permanents est magnétisé et définit au moins un pôle d'induit. Un support latéral agit entre l'élément cylindre et l'élément de liaison, en un point intermédiaire entre le matériau de l'aimant permanent et le piston. Le support latéral autorise un déplacement axial de la bielle tout en transférant les charges latéral à l'élément cylindre.
