Problems solved by technology

In the event that refrigerant gas accumulates at a certain point in the lubricant supply channel, the gas pressure gradually increases, thereby hindering the lubricant supply, creating air stagnation in the lubricant supply channel, causing some parts to lubricate insufficient

Embodiment Construction

[0025] The following descriptions of various embodiments of the present invention are exemplary only, and in no way limit the present invention and its application or usage. The same reference numerals are used to denote the same components in the respective drawings, and thus the configurations of the same components will not be described repeatedly.

[0026] This paper takes a scroll compressor as an example to describe the principle and idea of ​​the present invention. It should be understood, however, that the present invention is not limited to the scroll compressors shown or described herein, but various types of suitable compressors. For example, the present invention is not limited to the illustrated vertical compressors, but is also applicable to horizontal compressors.

[0027] The following will refer to figure 1 Describe the general construction and operating principles of a scroll compressor. like figure 1 As shown, the scroll compressor 100 (hereinafter somet...

Abstract

The invention relates to a compressor. The compressor comprises a shell body, a compression mechanism, a driving shaft and an exhaust passage, wherein the compression mechanism is arranged in the shell body, and comprises a fixed vortex part and a movable vortex part capable of moving relative to the fixed vortex part so as to compress a working fluid, the driving shaft and the movable vortex partof the compression mechanism are assembled together to drive the movable vortex part, a lubricant supply passage is formed in the driving shaft, the lubricant supply passage extends to an oil discharge port at the end face of the driving shaft so as to make a lubricant to be discharged out of the driving shaft, and the exhaust passage is arranged in the movable vortex part so as to discharge gasaccumulated in a space between the end face of the driving shaft and the movable vortex part. According to the compressor, due to the arrangement of the exhaust passage, the gas stagnation of the lubricant supply passage can be avoided or reduced, and then the lubricant can be stably supplied to each moving part of the compressor.

Description

technical field [0001] The present invention relates to a compressor, in particular to a compressor with an exhaust channel for discharging flash gas in lubricant. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] A compressor generally includes a housing, a compression mechanism disposed in the housing for compressing a working fluid (eg, refrigerant), and a driving mechanism disposed in the housing for driving the compression mechanism. There is an oil storage tank at the bottom of the housing, and the lubricant in the oil storage tank flows to each moving part through the supply channel in the drive mechanism to lubricate the moving parts. [0004] Refrigerant is often mixed with the lubricant in the sump. As the lubricant is supplied to the various moving parts, the lubricant and refrigerant mixture is heated and the lubricant flashes out due to...
