Abstract:
A reciprocating compressor with a linear motor, comprising a hermetic housing (10), which lodges a cylinder (20), a piston (30) reciprocating inside the cylinder and a rod (40), which is coupled to the piston (30) and which is axially displaceable by a linear motor (50), characterized in that it further comprises: a first supporting means (70), connecting the cylinder (20) to the housing (10), and a second supporting means (80), connecting the rod (40) to the housing (10), said first and second supporting means (70, 80) being elastically deformable, in order to allow the axial displacement of the cylinder (20) and of the piston-rod assembly (30, 40) between a lower dead point position and an upper dead point position of the piston; a first annular motor portion (51) and a second annular motor portion (52), which are mutually coaxial and coupled to the cylinder (20) and to the rod (40), respectively, and which are axially and 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.
