Abstract

The invention relates to the technical field of refrigeration compressors, in particular to an exhaust device of a rotary compressor; in the exhaust device of the rotary compressor, a piston channel is arranged on a wall of an air cylinder, the bottom part of the air cylinder is provided with an exhaust port communicated with an air cylinder cavity, the inner end of a piston is tightly close to and blocks the exhaust port under the action of spring thrust; when the compressor exhausts air in the working process, the piston slides outwards in a piston channel, so as to remove blocking to the exhaust port, at the moment, high-pressure air in the air cylinder cavity is exhausted outside a compressing cavity through the exhaust port and an exhaust pipeline; the exhaust device in the inventioncan reduce clearance volume of the compressor in the exhaust process, and the efficiency of the compressor is improved; the mechanical noise generated by repeat beating is avoided when the traditionalcompressor is exhausted; in addition, a plurality of exhaust devices are arranged on the air cylinder wall according to needs, so as to bear the exhaust pressure respectively, reduce the exhaust resistance and reduce energy loss.

Description

technical field [0001] The invention relates to the technical field of refrigeration compressors, in particular to a rotary compressor exhaust device. Background technique [0002] The compressor is the core equipment for compressing the refrigerant in the refrigerator and air-conditioning system to make it participate in the cycle. The rotary compressor is a commonly used compressor. The rotary compressor generally includes a rotary compressor and a swing compressor. The work is completed in the sealed cylinder chamber of the compressor. The upper flange and the lower flange are arranged at both ends of the cylinder to form a sealed cylinder chamber. The compression of the gas is carried out in the cylinder chamber. The compressed gas in the cylinder chamber is properly When the high pressure is discharged from the cylinder chamber through the exhaust device. [0003] The exhaust device of the prior art rotary compressor (see figure 1 ) Usually, the upper and lower flange...
