Compressor

Abstract

The invention provides a compressor. The compressor comprises an air cylinder, a roller and a sliding piece set, wherein the roller is rotationally arranged in a cavity of the air cylinder; the sliding piece set is arranged in a sliding piece groove of the air cylinder in a sliding manner; the sliding piece set comprises a low-pressure side sliding piece and a high-pressure side sliding piece; anair suction cavity is formed by the area among the low-pressure side sliding piece, the roller and the inner wall of the air cylinder; a compression cavity is formed by the area among the high-pressure side sliding piece, the roller and the inner wall of the air cylinder; the low-pressure side sliding piece is provided with a limiting groove; the limiting groove is provided with a first side wallarranged in the axial direction of the sliding piece groove and a second side wall arranged in the radial direction of the sliding piece groove; and the side wall of the high-pressure side sliding piece is in limiting fit with the first side wall, and the tail end of the high-pressure side sliding piece is in limiting fit with the second side wall. By the adoption of the scheme, the problem of sliding piece disengaging can be solved, leakage is reduced, and the performance of the compressor is improved.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a compressor. Background technique [0002] Existing rotary compressors generally use a single vane, and rely on the pushing pressure of the spring to make the end of the vane tightly pressed against the outer surface of the roller, and the vane and roller divide the cavity in the cylinder into suction The air cavity and the compression cavity use the rotation of the crankshaft to drive the rollers to move, while the sliding plate reciprocates, and the cylinder repeatedly performs the suction, compression and discharge of gas to complete the basic functions of the compressor. However, because the sliding vane is in line contact with the outer circle of the roller, the top of the sliding vane is prone to wear under the force of the spring and the pressure difference, especially when the operating speed of the compressor is getting higher and higher, the wear is more ob...

AI Technical Summary

Problems solved by technology

The detachment of the sliding vane will cause abnormal noise, and the leakage of the working chamber will increase when it is detached, which will affect the performance of the compressor

Therefore, the double slider setting is an effective technical means to improve the force of the slider, but it increases the risk of the slider falling off
