Problems solved by technology

[0015] That is, the problem of the structure as described above is that the efficiency of the compressor is reduced, that is, because the volume of the valve through-hole 11 formed between the above-mentioned valve plate 13 and the compression chamber 6 is inevitably increased, resulting in a problem caused by the valve. The recompression loss due to the increased volume of the through hole 11
[0016] In addition, the problem with the above-mentioned structure is that if it is used for a long time, the above-mentioned valve plate 13 will rotate at a certain angle. Therefore, the above-mentioned valve plate 13 cannot be completely closed and the compressor is damaged.

Abstract

The present invention relates to a check valve device of scroll compressor. The valve plate on the fixed scroll is pressure fixed and has valve hole for the refrigerant to flow to the compression chamber on one end, so that the present invention has reduced volume outside the compression chamber and raised compressor efficiency. The present invention is practical.

Description

technical field [0001] The invention relates to a compressor, in particular to a check valve device (CHECK VALVE OFSCROOL COMPRESSOR) of a scroll compressor which is arranged on the fixed scroll of the scroll compressor and regulates the flow of refrigerant. Background technique [0002] Generally speaking, as a device for compressing refrigerant gas and other fluids, compressors can be divided into rotary compressors, reciprocating compressors, and scroll compressors according to the way the compressors compress fluids. [0003] The embodiments of the existing scroll compressor will be described in detail below in conjunction with the accompanying drawings. [0004] figure 1 The diagram shows the structural drawing of the existing scroll compressor; figure 2 , image 3 It is an existing scroll compressor, and the diagram shows the structure and connection state of the check valve device. [0005] As shown in the figure, the scroll compressor includes: a main body; a po...
