Compressing mechanism and compressor with same

Abstract

The invention discloses a compressing mechanism and a compressor with the same. The compressor comprises a cylinder, an exhaust hole, a piston, a crankshaft, an upper bearing, a lower bearing, a slidepiece, a discharge valve plate and a transmission part. A cylinder chamber and a slide piece groove are formed in the cylinder. The exhaust hole communicates with the cylinder chamber. The upper bearing and the lower bearing rotationally support the crankshaft. The slide piece is disposed in the slide piece groove and can reciprocate between an inner limit position and an outer limit position. The discharge valve plate is used for opening or closing the exhaust hole. The transmission part is provided with a valve plate contact part and a slide piece contact part. The slide piece drives the slide piece contact part when moving outwards so that the valve plate contact part of the transmission part can push the discharge valve plate to close the exhaust hole. The slide piece contact part andthe valve plate contact part are made of a high-surface-hardness, wear-resistant, light or elastic material. According to the compressing mechanism, the discharge valve plate is high in applicabilityand reliability, low in closing noise and high in energy efficiency.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a compression mechanism and a compressor having the same. Background technique [0002] The discharge valve plate is an important part of the rotary compressor, and the discharge valve plate affects the energy efficiency, power consumption, noise, etc. of the compressor. Various improvements to the structure and material of the exhaust valve plate itself have been proposed in the related art, but each of these improvement solutions has its own problems, so there is a demand for improvement. The inventor found and realized through research that the greater the stiffness of the exhaust valve plate, the better the timeliness of closing the exhaust valve, the higher the reliability, and the lower the noise of impacting the valve seat. However, the greater the stiffness of the exhaust valve plate, the slower the opening, the smaller the opening range, and the smaller the ...

AI Technical Summary

Problems solved by technology

However, the greater the stiffness of the exhaust valve, the slower the opening, the smaller the opening range, and the smaller the exhaust flow area, resulting in greater loss of exhaust resistance and greater power consumption of the compressor, which leads to the loss of the exhaust valve. Rigidity design is difficult, design flexibility is limited, and the applicability and reliability of the exhaust valve plate are poor
