Abstract
A linear compressor (1) includes a cylinder (21) with a piston (22) connected through a main spring (19) and a planar spring (20). One or more flat blocks of permanent magnet material (17) with large faces of the blocks facing a stator (15) and defining armature poles are secured to a connecting rod (30). A lateral support (52) acts between the cylind (21) and the connecting rod (30) at a location midway between the permanent magnet material and the piston (22) allowing axial movement of the connecting rod (30) but transferring side loads to the cylinder (21).
