Problems solved by technology
When the high-pressure refrigerant gas is discharged from the cylinder cavity, the cross-sectional area of the flow channel suddenly decreases when the refrigerant gas enters the exhaust hole. The airflow velocity above will form a large velocity gradient, which hinders the smoothness of the exhaust, increases the exhaust input force of the compressor, and greatly reduces the energy efficiency of the compressor.

The invention discloses a compression mechanism of a compressor, and a compressor with the same. The compression mechanism comprises a cylinder, a bearing, a piston, a slide sheet and a flow guide notch, wherein a slide sheet groove and a cylinder cavity are limited in the cylinder; the bearing is arranged on the end surface of the cylinder, an exhaust hole is formed in the bearing, and the inlet end of the exhaust hole communicates with the cylinder cavity; the piston is arranged in the cylinder in a manner of eccentrically rotating; the slide sheet is arranged in the slide sheet groove in a manner of carrying out reciprocating motion, and the inner end of the slide sheet is abutted against the outer circumferential wall of the piston; and the flow guide notch is only located in an arranged cylinder, and the projection of the cylinder on an end surface is in a set fan shape. According to the compression mechanism of the compressor, the flow guide notch is formed in the inner circumference of the inlet end of the exhaust hole, and the flow guide notch is simple in structure, easy to machine, and capable of reducing the loss of an exhaust vortex at the inlet of the exhaust hole, and lowering the velocity gradient of airflow on the outlet section of the exhaust hole, so that the exhaust flow speed of the exhaust hole can be lowered, the input pressure of the compressor can be increase, and thus the energy efficiency of the compressor can be increased.
Description
technical field [0001] The invention relates to the field of compressors, in particular to a compression mechanism of a compressor and a compressor having the same. Background technique [0002] The hermetic compressor compresses the refrigerant in the cylinder chamber of the compressor. Once the refrigerant gas is compressed to a specified pressure in the cylinder chamber, the exhaust valve will open, and the refrigerant gas will be discharged out of the cylinder chamber through the exhaust hole. . [0003] Usually the exhaust hole is designed as a regular turning surface, and chamfering and deburring will be set near the end surface of the cylinder. When the high-pressure refrigerant gas is discharged from the cylinder cavity, the cross-sectional area of the flow channel suddenly decreases when the refrigerant gas enters the exhaust hole. The airflow velocity above will form a large velocity gradient, which hinders the smoothness of the exhaust, increases the exhaust i...
