RECIPROCATING COMPRESSOR

摘要

PURPOSE: A reciprocation compressor is provided to increase motion straightness of a magnet holder and piston by making the side force generated in a resonance spring offset. CONSTITUTION: A frame is elastically supported with the inside of a sealed container. A reciprocating motor includes a stator core and a magnet holder. The stator core is formed at the frame and has an air gap. A coil is wound in the stator core to form the magnetic field. A magnet holder(35) reciprocates and supports the magnet arranged to the air gap of the stator core. A cylinder(41) is supported in the frame. A piston(42) compresses a refrigerant while reciprocating, is combined with the magnet holder and is inserted in the cylinder. Resonance springs(51,52) induce a piston resonance-exercise by supporting flexibly the piston.
