Abstract

The invention provides an air cylinder and a compressor, and solves the technical problem that air suction efficiency cannot be further improved due to the fact that design of a U-shaped air suction channel of the air cylinder of the compressor cannot meet four key design factors simultaneously. According to the technical scheme, the air cylinder comprises an air cylinder body, a slide sheet groove formed in the air cylinder body and an air suction port formed in one side of the slide sheet groove, wherein a cross section of the air suction port is of a groove structure, and a groove comprisesa first circular arc section, a second circular arc section and a plurality of extended sections. According to the air cylinder and the compressor, the inner wall of the groove is set into multiple arc sections, the eddy phenomenon near the air suction port can be effectively reduced, air suction resistance caused by eddy is reduced, and compression efficiency of the compressor is improved. Meanwhile, by means of the groove with multi-arc-section inner wall, when the air suction port is designed, setting and adjustment of each key parameter affecting the air suction efficiency of the air suction port are further facilitated, great convenience is brought to design of the air suction port, and workload of the design is reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a cylinder and a compressor. Background technique [0002] The cylinder of the rotary compressor is equipped with a suction structure and an exhaust structure. Its working principle is: the crankshaft drives the rollers in the cylinder to make a partial circular motion, and the rollers and the sliding plates that withstand the rollers compress the compression chamber in the cylinder. It is divided into a suction chamber and an exhaust chamber. When the crankshaft drives the roller to rotate, the cylinder sucks the gas into the suction chamber through the suction structure and discharges it from the exhaust structure, so as to realize the compression of the gas. [0003] The suction structure on the cylinder has a significant impact on the performance and energy efficiency of the compressor. Such as figure 1 and figure 2 As shown, the suction structure on the common compre...
