Abstract
A reciprocating compressor including: a closed container (); a reciprocating motor () having stators and an armature () disposed in the air gap between the stators () and making a reciprocal movement; a compression unit () having a piston () combined with the armature () of the reciprocating motor and a cylinder fixed inside the closed container (); a spring unit () elastically supporting the armature () of the reciprocating motor () in a movement direction; and a frame unit () supporting the reciprocating motor () and the compression unit () having a gas hole () at a suitable portion thereof. Accordingly, when the armature () of the reciprocating motor () makes a reciprocal movement, the gas is compressed at the end of the armature (), so that an increase of a flow resistance is prevented. In addition, in occurrence of an over-stroke of the armature, as the step portion () makes a space to prevent the magnet from releasing or damaging, the reliability of the compressor is improved.
