Abstract

The present invention relates to a reciprocating compressor wherein a moving member (103) reciprocates linearly inside a stationary member to compress refrigerant, and more particularly, to a reciprocating compressor wherein a backflow of refrigerant is prevented before the refrigerant is introduced into a compression space. A reciprocating compressor according to the present invention includes a hollow stationary member, a moving member reciprocating linearly inside the stationary member, and having a suction hole (103a) in a blocked end so that refrigerant can be introduced therethrough, a sound attenuation duct (111 ) extended lengthwise inside the moving member (103) to guide introduced refrigerant, and a backflow prevention portion expanded from an end of the sound attenuation duct (111 ) toward the moving member (103) to prevent a backflow of the refrigerant. As the refrigerant does not flow backward before it flows into a compression space, it is possible to improve the compression efficiency.
