Abstract
An oil supply apparatus for a hermetic compressor includes: a crankshaft coupled with a rotor of 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 revolve in a direction opposite to that of the sleeve to carry out a suction of an oil, and a rotating force transferring means for supporting the sucking member so that the sucking member revolves together with the sleeve and receiving a rotating force of the sleeve so as to revolve the sucking member in a direction opposite to a revolving direction of the sleeve. The relative revolution speed between the sleeve and sucking member increases so as to increase the oil supply to the sliding and frictional parts, thereby enabling to improve a lubrication performance of the compressor. When the compressor generates vibration, the sucking member and sleeve vibrate with the same amplitude so as to maintain uniformly the gap between the sleeve and sucking member. Therefore, the present invention enables to improve a reliance of the oil supply.
