Oil suction device for hermetically sealed compressor
First Claim
1. An oil suction device in a hermetically sealed compressor, said compressor comprising:
- a rotor;
a crank shaft pressure-inserted in the rotor;
an oil guide piece formed in a three tiered conical shape and adapted to be pressure-inserted in a lower portion of the crank shaft;
an oil suction propeller fixedly inserted in the oil guide piece, the oil suction propeller being formed in a three tiered conical shape containing a lower portion, an upper portion and an intermediate portion extending between the lower and upper portions;
wherein the suction propeller is inserted in the crank shaft of the hermetically sealed compressor the lower portion soaked in oil in said compressor, the upper portion having a width wider than that of the lower wing; and
the intermediate portion gradually broadening in width toward the upper portion, the upper portion and lower portion being twisted relative to the intermediate portion.

Abstract
An oil suction propeller structure for a hermetically sealed compressor includes a rotor, a crank shaft pressure-inserted in the rotor, an oil guide piece pressure-inserted in a lower portion of the crank shaft, a lower wing fixedly inserted in the oil guide piece and soaked in an oil, an upper wing having a width thereof wider than that of the lower wing, and an intermediate portion extending from the lower wing and gradually broadening in width toward the upper wing. The oil suction propeller structure improves oil supply capacity, and minimizes a whirling sound and a dropping noise which may occur during the rotation of the oil guide piece and the oil suction propeller thereof, for thereby enhancing reliability of the hermetically sealed compressor.
