Abstract:
A hermetic compressor uses an oil pump that includes a trochoid gear. Therefore, regardless of the rotation speed of a driving motor of the compressor, a sufficient amount of oil can always be pumped. The oil pump unit may include a plurality of suction holes with openings at different heights. If the refrigerant and oil separate, at least one of the openings will admit oil into the oil pump unit, to ensure lubricating oil is supplied to the moving parts of the compressor.
