Abstract

The invention provides a rotary compressor exhaust device, which includes a compressor main bearing, a stopper, a compressor cylinder, a cylinder exhaust hole, a partially spherical exhaust valve plate and a conical exhaust hole. The main bearing is fixed on the compressor cylinder, and the compressor cylinder is provided with a cylinder exhaust hole. The above-mentioned partial spherical exhaust valve plate is fixed on the compressor main bearing, and a conical exhaust hole is arranged on the compressor main bearing. The local sphere of the partially spherical exhaust valve plate is aligned with the conical exhaust hole, and the above-mentioned limiter is arranged on the upper surface of the partially spherical exhaust valve plate and fixed on the main bearing of the compressor. The beneficial effects of the present invention are: the cylindrical exhaust hole is designed as a conical exhaust hole, which expands the exhaust area under the same circumstances, relatively reduces the clearance volume caused by the existence of the exhaust hole, and improves Improve the volumetric efficiency of the compressor and reduce noise.

Description

technical field [0001] This invention relates to compressors, and more particularly to rotary compressor dischargers. Background technique [0002] In the compressor structure of the prior art, the internal exhaust system is mainly composed of: compressor main bearing 1, exhaust valve plate 2, limiter 3, compressor cylinder 4, etc., the refrigerant gas in the compression chamber is compressed to a certain After a certain degree, the valve plate 2 is bounced up through the exhaust hole 5 of the cylinder and the exhaust hole 6 of the main bearing, so that the high-pressure refrigerant is discharged. FIG. 1 shows the related exhaust system structure of a compressor in the prior art. A cylindrical exhaust hole 6 is provided on the main bearing, and a flat plate valve plate 2 is provided to cover and seal the exhaust hole 6 . The larger the exhaust hole 6 diameter, the better the exhaust effect. However, the larger the diameter, the larger the clearance volume, resulting in low...
