Abstract

The present invention provides one kind of sliding-vane rotary compressor. Inside the limited volume of high pressure compartment, the high pressure chamber is set to have volume greater than that of oil storing chamber to prevent resonance between the refrigerating circulation parts, such as the heat exchanger, and the relevant vehicle members and to avoid abnormal sound. The sliding-vane rotary compressor includes high pressure chamber for the compressed fluid to be exhausted into, oil storing chamber for the lubricant oil separated from the high pressure fluid to be stored in, and sliding vane back pressure controller to provide the sliding vane back pressure chamber with gaseous fluid or lubricant oil from the oil storing chamber optionally. By means of setting the sliding vane back pressure controller set inside the high pressure chamber, the present invention can ensure the volume of the high pressure chamber and the fluid supply from the high pressure chamber to the sliding vane back pressure controller.

Description

technical field

[0001] The present invention relates to a compressor for compressing and discharging a fluid, and more particularly, to a compressor used in an automobile air conditioner and the like. Background technique

[0002] In a general compressor installed in a vehicle air conditioner, a part of the compressor lubricating oil is discharged into the refrigeration cycle part of the air conditioner together with the fluid (refrigerant) compressed by the compression mechanism.

[0003] The more compressor lubricating oil is discharged into the refrigerating cycle part together with the fluid (gas refrigerant), the lower the heat transfer efficiency of the heat exchanger in the refrigerating cycle part is. In addition, the pipe pressure loss in the refrigeration cycle components will also increase, and the efficiency of the refrigeration cycle will decrease.

[0004] The existing method for solving the above problem is to install in the compressor: an oil storage chamber...
