Problems solved by technology

[0011] However, in the existing scroll compressor, when compressing the refrigerant, the pressure between the bearing surface 66 and the movable scroll 32 is stronger than the relative oil supply pressure, so it is difficult to fully supply oil, and it is even more difficult to form a sufficient thickness. oil film
In addition, in order to recover oil, an oil discharge passage 67 penetrating with the outside of the upper support frame 61 is formed on one side of the oil storage part 64, so the oil pressure cannot be increased to a certain extent, therefore, the bearing surface 66 and the movable scroll 32 will produce relatively large friction and heat generation on the contact part, thus shortening the life of the compressor and reducing the performance of the compressor

Abstract

A vortex compressor with oil regulating function has a sealed casing, a static vortex disk, a moving vortex disk able to move relatively to said static vortex disk, a rotary shaft for making the moving vortex disk move eccentrically and providing oil channel, and moving vortex disk supporter with central oil recepting part and oil discharge channel. Said oil discharge channel has a valve to open or close it for holding the oil pressure in a range to increase the thickness of oil film on bearing surface.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular to an invention related to a scroll compressor with an oil regulating function. Background technique [0002] As shown in Figures 1 and 2, the structure of the scroll compressor includes: a shell 11 forming a closed space inside; a compression part 21 located on the upper part of the shell 11 for compressing the refrigerant; It is the motor part 41 which supplies the driving force to the compression part 21. [0003] On one side of the housing 11 is provided a suction pipe 13 for sucking in the refrigerant from the outside, and on the upper side of the suction pipe 13 is provided a discharge pipe 15 for discharging the compressed refrigerant. [0004] The structure of the compression part 21 includes: a fixed scroll 22 with an involute-shaped fixed wing 23 installed inside the casing 11; it moves relative to the fixed scroll 22 and has a rotating wing 33 corresponding to the involute ...
