RECIPROCATING COMPRESSOR

摘要

Disclosed is a reciprocating compressor, including a latching unit (50) which uses a magnetic force generated between magnets (61,62) disposed in a shaft direction and by which a piston (40) is reciprocated by two times a total eccentric amount obtained by adding an eccentric amount of an eccentric portion (11 ) to an eccentric amount of an eccentric sleeve (20) in a power mode, while the piston (40) is reciprocated by two times the eccentric amount of the eccentric portion (11 ) in a saving mode, whereby the piston (40) 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 (40) and a discharge valve and increasing a variable ratio of a cooling capacity of the compressor in the saving mode.
