Abstract

A reciprocating compressor with a linear motor, comprising a hermetic housing (10), which lodges a cylinder (20), a piston (30); a rod (40), which is coupled to the piston (30) and which is axially displaceable by a linear motor (50); a first supporting means (70) and a second supporting means (80), which are elastically deformable and coupled to the housing (10) and, respectively, to the cylinder (20) and to the rod (40), and which are electromagnetically displaceable in opposite directions, in order to provoke the axial displacement of the cylinder (20) and of the piston-rod assembly (30, 40) between the upper and lower dead point positions.
