Compressor
By introducing an oil pump mechanism and oil inlet/outlet channels connected to the compression mechanism into the scroll compressor, the problems of poor thrust surface lubrication and excessively high oil circulation rate are solved, thereby improving the lubrication effect and simplifying the structure, and promoting the miniaturization of the compressor.

AI Technical Summary
The existing oil supply system of scroll compressors has poor lubrication of the thrust surface when running at low speed, and excessively high oil circulation rate when running at high speed. In addition, the complex structure is not conducive to miniaturization.
An improved oil supply system is adopted, which includes an oil pump mechanism connected to a compression mechanism and driven by the compression mechanism. The lubricating oil is delivered to each component to be lubricated, especially the thrust surface, through the oil inlet and outlet channels in the main bearing housing. This simplifies the structure and improves the lubrication effect and oil circulation control.
It achieves stable lubrication of the thrust surface, reduces oil churning power consumption, controls oil circulation rate, simplifies compressor structure, and facilitates miniaturization.
