Oil supply apparatus for hermetic compressor

Abstract

An oil supply apparatus for a hermetic compressor includes: a crankshaft coupled with a motor so as to revolve together and having an oil flow path inside, a sleeve connected to a lower part of the crankshaft so as to revolve together with the crankshaft in one body, a sucking member arranged to maintain a uniform interval with an inner circumference face of the sleeve so as to carry out a suction of an oil, and a support means for supporting the sucking member to slide, the support means connected between the sleeve and sucking member so as to maintain a stationary state. The sucking member is supported so as not to revolve at the revolving center of the sleeve, thereby maintaining a uniform gap between the inner circumference face of the sleeve and the sucking member regardless of the vibration from the actuating compressor so as to improve oil supply reliance.
