Rotary compressor

Abstract

The invention discloses a rotary compressor. The rotary compressor comprises a cylinder component, a main bearing, a secondary bearing and an exhaust device, wherein the cylinder component comprises a cylinder with a compression cavity; the main bearing and the secondary bearing are respectively arranged at the top and the bottom of the cylinder component; exhaust holes are formed in the main bearing and / or the secondary bearing, and consist of center holes and gas channel cavities; one ends, near the compression cavity, of the center holes are configured as inlet ends of the exhaust holes; one ends, far from the compression cavity, of the center holes and the gas channel cavities are configured as outlet ends of the exhaust holes; the exhaust device comprises exhaust valve pieces, stop components and elastic pieces; the exhaust valve pieces are arranged at the inlet ends for opening or closing the inlet ends; the stop components are arranged in the center holes, and are positioned at one sides, near the outlet ends, of the exhaust valve pieces; and the elastic pieces are arranged between the exhaust valve pieces and the stop components, and fit the stop components. According to the rotary compressor disclosed by the invention, the vertical movement of the exhaust valve pieces is smooth; and the harmful runout of the elastic pieces in the exhaust holes is limited.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a rotary compressor. Background technique [0002] Although systems equipped with rotary compressors are becoming more and more popular all over the world, the work efficiency of rotary compressors has been greatly improved compared with the initial stage of invention through the improvement of structure and the change of some materials, but as an important structural part of rotary compressors, Tongue type exhaust valves have been used for many years. [0003] The bearings of conventional rotary compressors equipped with tongue-type exhaust valves have a large area of ​​the valve receiving groove and a thin bottom surface, which reduces the rigidity of the bearings, which makes the bearings easily deformed when the rotary compressor is working, which not only brings Efficiency is lost, and reliability is also reduced. Contents of the invention [0004] The present inve...
