Abstract
The present invention relates to a reciprocating compressor. The reciprocating compressor includes a latching unit by which a piston 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 in a power mode, while the piston is reciprocated by two times the eccentric amount of the eccentric portion in a saving mode, accordingly the piston can have an upper dead point same in the power mode and the saving mode, thereby reducing a dead volume between the piston and a discharge valve and increasing a variable ratio of a cooling capacity of the compressor in the saving mode.
