Compression mechanism and compressor having it

Abstract

The invention discloses a compression mechanism and a compressor with the same. The compressor includes a cylinder, the cylinder has a cylinder chamber and a slide slot; an exhaust hole, the exhaust hole communicates with the cylinder chamber; a piston; a crankshaft; an upper bearing and a lower bearing, the upper bearing and the The lower bearing rotatably supports the crankshaft; the sliding vane is arranged in the sliding vane groove and can reciprocate between the inner limit position and the outer limit position; the exhaust valve plate, the row The air valve plate is used to open and close the exhaust hole; the transmission part has a valve contact part and a slide contact part, and the slide contact part is driven when the slide moves outward, so that the valve of the transmission part The contact part of the sheet pushes the exhaust valve sheet to close the exhaust hole, and the contact part of the slide sheet and the contact part of the valve sheet are made of materials with high surface hardness, wear resistance, light weight or elasticity. According to the compression mechanism of the present invention, the applicability and reliability of the exhaust valve plate are good, the closing noise is low, and the energy efficiency is high.

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
