RECIPROCATING COMPRESSOR

摘要

Disclosed is a reciprocating compressor, including a latching unit which uses a magnetic force generated between magnets disposed in a shaft direction and 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, whereby the piston 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 and a discharge valve and increasing a variable ratio of a cooling capacity of the compressor in the saving mode.
