Disclosed is a reciprocating compressor having an assembly structure of a suction muffler, in which a supporting unit is formed on an inner circumferential surface of a resonant container of the suction muffler and a baffle is assembled in the resonant container by the supporting unit. By forming protrusions in the resonant container and inserting a baffle between the protrusions, the suction muffler can be easily and simply assembled. Accordingly, production costs can not only be reduced but also an increased noise reduction effect is obtained by precisely regulating an assembly position.

Reciprocating compressor having assembly structure of suction muffler

A reciprocating compressor includes: a reciprocating motor, an outer stator and an inner stator provided with at least one step portion at both sides thereof, and an armature linearly moving therebetween; a compression unit having a cylinder and a piston inserted in the cylinder to receive a linear and reciprocal driving force of the reciprocating motor and compress a gas; a suction unit sucking a gas into the compression unit; a discharge unit discharging the gas compressed in the compression unit to outside the container; a resonance spring unit elastically supporting the piston and the armature; and a frame unit supporting the compression unit and the reciprocating motor. Because stable driving is achieved in its operation, generation of vibration and noise can be minimized, heightening reliability. In addition, the amount of gas discharge can be accurately controlled.

Reciprocating compressor having reduced vibration

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.
