ABSTRACT:
An oil supplying apparatus for a horizontal type rotary compressor capable of securing a substantial oil supplying and preventing oil leakage to the outside thereof thereby enhancing higher oil supplying efficiency of the compressor is disclosed. The present invention includes a body of a horizontal type rotary compressor; a rotary shaft including an oil path and an eccentric rotary shaft; and a crank shaft passing through a main bearing, in which the outer entire circumferential surface thereof is sealingly fixedly affixed to the entire inner circumferential surface of the body, including a refrigerant guide opening, formed at a predetermined portion of the circumferential surface thereof, having a predetermined diameter for guiding the compressed refrigerant therethrough, a bolt opening formed below the refrigerant guiding opening having a predetermined diameter, a rotary shaft opening formed at the center portion thereof having a predetermined diameter, an injection portion formed below the rotary shaft opening for injecting the compressed refrigerant therethrough, and an oil opening formed below the injection portion for passing the oil therethrough.
