Problems solved by technology

Due to the large area of ​​the weak part of the reed valve seat and the large pressure difference on both sides of the seat wall, if the valve seat is too thin, the bearing may face the inner depression of the cylinder, resulting in metal friction between the bearing surface and the piston, or even Stall

Abstract

The invention relates to a compressor exhaust apparatus, the compressor comprises a compression component and a motor component arranged in a closed casing; the compression component comprises a cylinder, a piston arranged in the cylinder, an eccentric crankshaft capable of driving the eccentric rotation of the piston, a slide plate arranged in a slide plate groove of the cylinder, a main bearing and an auxiliary bearing respectively arranged at two sides of the cylinder; the exhaust apparatus comprises a bearing valve seat arranged on the base bearing, and an exhaust valve sheet, a spring and a stopper which are arranged in the bearing valve seat; a valve seat steam vent is provided at the lower part of the bearing valve seat, a spacing hole is provided at the upper part of the valve seat steam vent; the exhaust valve sheet is carried on the valve seat steam vent, and is capable of moving up and down along an axial direction of the spacing hole; the stopper is positioned at the upper part of the exhaust valve sheet, and is fixedly connected to the spacing hole inner wall; the spring is subjected to pressure welding between the exhaust valve sheet and the stopper. The exhaust apparatus has the advantages of compact structure and simple assembling, can effectively reinforce the rigidity of the bearing valve seat; simultaneously the valve seat thickness is reduced, the clearance volume of the valve seat steam vent is reduced, and the cold amount can be increased.

Description

technical field [0001] The invention relates to an exhaust device of a compressor. Background technique [0002] The reed valve has the characteristics of simple structure, light moving mass and small clearance volume, so it is widely used in micro air compressors and refrigeration compressors. Due to the large area of ​​the weak part of the reed valve seat and the large pressure difference on both sides of the seat wall, if the valve seat is too thin, the bearing may face the inner depression of the cylinder, resulting in metal friction between the bearing surface and the piston, or even Stall. [0003] Chinese Patent Document No. CN201436395U disclosed on April 7, 2010 an exhaust device for a closed rotary compressor, comprising an exhaust valve seat connected to the cavity of the cylinder, and one end of the exhaust valve seat is provided with a The exhaust hole connected to the cavity, the other end of the exhaust valve seat is fixedly connected with the stacked exhaus...
