Rotary compressor

Abstract

The invention relates to a rotary compressor, mainly composed of a compression cavity case 1, a rotary piston 2, a compression cavity inner case shaft 3, a rotating shaft 5, an air inlet / exhaust shaft 6, a sealed cam 9, a sealed cam shaft 10, a sealed cam case 11 and a gear transmission system. The rotary piston 2 rotates in the circular cavity formed by the internal surface of the compression cavity case 1 and the external surface of the compression cavity inner case shaft 3, the sealed cam 9 divides the circular cavity into two regions, and air inlet and compression processes are respectively carried out in the two regions. The compression cavity inner case shaft 3, the rotating shaft 5 and the air inlet / exhaust shaft 6 are respectively opened with air inlet / exhaust ports on the shaft surface, and the air inlet / exhaust ports are periodically closed and opened when the rotating shaft 5 rotates, thus low pressure gas is allowed to enter while high pressure gas is exhausted. The rotary piston 2, the rotating shaft 5 and the sealed cam 9 regularly rotate and interact with each other by the gear transmission system. The rotary compressor has simple shape, easy processing and reliable sealing and can be widely applied to the refrigeration and air conditioning industrial fields.

Description

technical field [0001] The rotary compressor proposed by the invention can be used in refrigeration, low temperature, internal combustion engine and other industrial fields, and has broad application prospects. Background technique [0002] Existing small compressor structures such as rotary compressors, oblique piston compressors, scroll compressors, screw compressors, etc., are relatively simple in structure, but the compression ratio cannot be very high, such as scroll compressors, or Seals are prone to wear, such as rotary compressors, or difficult to process, such as screw compressors. Although the compression ratio of the reciprocating piston compressor can reach a very high value, the structure is complex, the mechanism is cumbersome, and the operation is not smooth. The working curved surface of the rotary compressor proposed by the present invention is a cylindrical surface, which is simple to manufacture. At the same time, each relative movement surface in the com...
