A compressor and an oil separating device therefor are provided which are capable of always maintaining a predetermined amount of oil in the compressor without additionally providing an oil separating device along a refrigerating cycle system. This results in the refrigerating cycle system having simplified piping and the refrigerant discharged from the compressor having a constant pressure, thereby preventing a function of the refrigerating cycle system from being reduced. The compressor includes a casing, a compression device having a compression chamber disposed within the casing and configured to receive, compress, and output a refrigerant, and an oil separating device disposed within the casing. The oil separating device includes a separation chamber configured to circulate the refrigerant to separate oil therefrom, a guide member configured to direct the refrigerant discharged from the compression device, and a circulation member configured to receive the refrigerant from the guide member and direct the refrigerant into the separation chamber in a direction of circulation.

Compressor and oil separating device therefor

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.

An oil feeding propeller of a scroll compressor for preventing deterioration of oil feeding generated when a rotation shaft is rotated in reverse is disclosed. The propeller is tightly fitted into the lower side of the oil passage of the rotation shaft, sucks oil into the shell due to rotation shaft of shaft to raise oil to a compression part of the scroll compressor. The propeller includes a plate without operative direction for feeding oil in a predetermined direction so as to raise a predetermined quantity of oil regardless of the rotation direction shaft.
