Apparatus for supplying oil of reciprocating compressor

Abstract

Disclosed is an apparatus for supplying oil of a reciprocating compressor, comprising: an oil cylinder installed at one side of a reciprocating compressor main body for linearly vibrating together with the compressor main body, an oil piston inserted in the oil cylinder and relatively moving according to the linear vibration of the oil cylinder and thus sucking an oil in the oil cylinder and pumping the oil into the compressor main body by varying pressure in the oil cylinder, a pair of springs installed in the oil cylinder for elastically supporting both ends of the oil piston and causing a continual relative movement of the oil piston according to the linear vibration of the oil cylinder and a spring fixing means fixing the pair of springs for maintaining a certain interval with an inner circumferential surface of the oil cylinder, which results in reducing damage due to friction between the oil cylinder and the springs and in improving an oil supplying function.
