Abstract:
A reciprocating compressor comprising:a frame supporting a cylinder, the frame being installed elastically inside a casing; a radially inner stator and a radially outer stator installed on the frame and forming a stator of a motor; an armature coupled integrally to a piston, which is slidably inserted into the cylinder, the armature being disposed with a certain gap between the inner stator and the outer stator; an inner resonance spring and an outer resonance spring supporting front and rear sides of the armature so that the armature undergoes linear resonant movement with the piston; and a stator supporting apparatus including a supporting member, one end of the inner stator being supported by the supporting member, the supporting member being elastically supported by one end of the inner resonance spring, so that the vibration of the resonance spring is transferred to the frame through the inner stator.
