Abstract

Disclosed is a reciprocating compressor, including a latching unit (140) which uses a magnetic force and by which a piston (123) is reciprocated by two times a total eccentric amount obtained by adding an eccentric amount of an eccentric portion to an eccentric amount of an eccentric sleeve (121 ) in a power mode, while the piston (123) is reciprocated by two times the eccentric amount of the eccentric portion in a saving mode, whereby the piston (123) can have an upper dead point same in the power mode and the saving mode of the compressor, resulting in reducing a dead volume between the piston (123) and a discharge valve and increasing a variable ratio of a cooling capacity of the compressor in the saving mode.
