Problems solved by technology

In this way, the oil supply thruster cannot lift the oil normally, and causes the opposite result, even if the oil that has been supplied to the compression part is lowered
[0013] In addition, when the rotating shaft rotates in the reverse direction, since the oil cannot be sufficiently supplied to the compression part, the compression part is damaged, and the reliability of the conventional scroll compressor is significantly deteriorated

Embodiment Construction

[0054] Hereinafter, an oil-feeding propeller of a scroll compressor according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0055] Figure 4 This is an enlarged cross-sectional view of a scroll compressor employing an oil-supplied thruster according to a first preferred embodiment of the present invention. Figure 5 It is a perspective view of the oil-supplied thruster of the scroll compressor according to the first preferred embodiment of the present invention.

[0056] like Figure 4 and Figure 5 As shown, the oil supply propeller 1 of the scroll compressor according to the first preferred embodiment of the present invention is tightly fitted on the lower side of the oil passage 3 formed in the rotating shaft 2 in the axial direction. And when the rotating shaft 2 rotates, the oil supply propeller 1 absorbs the oil stored in the casing 4 and lifts it to the compression part through the oil pa...

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.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular to an oil supply propeller of a scroll compressor for avoiding oil supply deterioration when a rotating shaft rotates in reverse. Background technique [0002] Generally, scroll compressors are high-efficiency, low-noise compressors widely used in the field of air conditioning. In a scroll compressor, when the scroll rotates, multiple compression chambers are formed between the two scrolls, and the compression chambers move toward the center of the scrolls, so the volume of the compression chambers decreases, and then the scrolls are mutually again separation, thereby drawing the refrigerant gas into the scroll compressor. [0003] figure 1 It is a vertical cross-sectional view of a conventional scroll compressor. [0004] like figure 1 As shown, the conventional scroll compressor includes: a rotating shaft 400, which is rotatably supported in the casing 100 by the main frame 200 a...
