Abstract
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.
Claims20
An oil feeding propeller of a scroll compressor comprising:
- an oil passage formed in a rotation shaft of the scroll compressor in the axial direction;
- and
- a plate tightly fitted in the lower side of the oil passage and rotated to raise a predetermined quantity of oil to a compression part of the scroll compressor via the oil passage regardless of rotational direction of the rotation shaft.
An oil feeding propeller of a scroll compressor comprising:
- an oil passage formed in a rotation shaft of the scroll compressor in the axial direction;
- a plate tightly fitted into the lower side of the rotation shaft and rotated together with the rotation shaft to raise a predetermined quantity of oil to a compression part of the scroll compressor via the oil passage regardless of rotational direction of the rotation shaft;
- and
- an inclined member integrally formed with the plate at an angle to reduce flow resistance of oil contacting the plate and to raise oil to the compression part.
The oil feeding propeller of a scroll compressor as set forth in claim, further comprising an elastic support formed at the lateral sides of the plate and elastically forcing the plate into close contact with the oil passage.
