Patent ID: 8177529

Claim:
A reciprocating compressor, comprising: a reciprocating motor including a first stator and a second stator separated to have an air gap there between, and a mover disposed between the first stator and the second stator, to perform a reciprocation; a frame to support the first and second stators; a cylinder coupled to the frame, inserted in the second stator, and forming a compression space therein; a piston inserted into the compression space of the cylinder to perform a reciprocation, and connected to the mover; and a magnetic flux guiding member disposed between a front surface of the second stator and a rear surface of the frame facing the front surface of the second stator in the reciprocation direction of the mover, to guide magnetic flux, wherein one side surface of the magnetic flux guiding member contacts the second stator in the reciprocation direction of the mover, and another side surface of the magnetic flux guiding member contacts one side surface of the frame in the reciprocation direction of the mover, wherein an entirety of an innermost radial surface of the second stator is in direct contact with the cylinder, and wherein the magnetic flux guiding member is formed of a material having conductivity higher than that of the frame.
