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

[0051] Hereinafter, an oil supply thruster of a scroll compressor according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0052] Figure 4 It is an enlarged cross-sectional view of a scroll compressor employing an oil-supply thruster according to a first preferred embodiment of the present invention. Figure 5 It is a perspective view of the oil supply thruster of the scroll compressor according to the first preferred embodiment of the present invention.

[0053] Such as Figure 4 and Figure 5 As shown, the oil supply impeller 1 of the scroll compressor according to the first preferred embodiment of the present invention is axially tightly fitted on the lower side of the oil passage 3 formed in the rotating shaft 2 . And when the rotating shaft 2 rotates, the oil supply thruster 1 sucks the oil stored in the housing 4 and lifts it to the compression part through the oil passage 3 .

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 invention relates to a scroll compressor, in particular to an oil supply impeller of the scroll compressor which is used to avoid deterioration of oil supply when the rotating shaft rotates in reverse. Background technique [0002] Generally, a scroll compressor is a high-efficiency, low-noise compressor widely used in the field of air conditioning. In a scroll compressor, when the scroll rotates, a plurality of 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 interact again separated, thereby drawing refrigerant gas into the scroll compressor. [0003] figure 1 It is a vertical sectional view of a traditional scroll compressor. [0004] Such as figure 1 As shown, the traditional scroll compressor includes: a rotating shaft 400, which is rotatably supported in the casing 100 by the main frame 200 ...
