Abstract

The rotary volumetric compressor includes cylinder with sealing end caps, fluid suction port and exhaust port and valve, and main shaft inside the cylinder. The main shaft and the inside of the cylinder are sealed, and inside the main shaft, there are runners and blocks inside the runners. The block ends are contacted with the inside wall of the cylinder to separate the inner cylinder cavity into high pressure cavity and low pressure cavity. The block has pressure relieving slot set for the residual fluid to be exhausted to the low pressure cavity while the block closes the exhaust port of the high pressure cavity. The present invention has the features of simple structure, small size, low cost, raised volume rate, low power consumption, less failure and long service life.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to rotary displacement compressors. Background technique [0002] In central air conditioners, car spaces, household air conditioners, refrigerators, booster pumps and other equipment, the compressor is the heart and key component of the above equipment, and its performance will directly affect the performance of the whole machine. Existing compressors include crankshaft type, swash plate type, etc. There are crankshaft, connecting rod, piston, valve plate, fixed plate, moving plate, blades, etc. in the crankshaft compressor cylinder, and there are pistons, pistons, etc. in the swash plate compressor cylinder. Ball pads, steel balls, swash plates and other parts have complex and unreasonable structures, resulting in defects such as large volume, high cost, low volume ratio, large energy consumption, many failures, and short life. Contents of the invention [0003] The purpose...
