Abstract

The present invention relates to a reciprocating compressor. According to the present invention, as an inner circumferential surface of a cylinder block (110) or an outer circumferential surface of a piston (140) is provided with a friction avoiding portion (142) by a specific length (Q) and a specific depth (H) or stepped surfaces forming the friction avoiding portion (142) are indented, a friction area between the cylinder block (110) and the piston (140) is decreased and a compression chamber (V1 ) is effectively sealed. Accordingly it is capable of enhancing reliability of the compressor.
