Abstract

The invention discloses a compression mechanism, a rotary compressor and a refrigerating device. The compression mechanism comprises an air cylinder, an exhaust vent, a piston, a crankshaft, an upperbearing and a lower bearing, a sliding piece, an exhaust valve plate and transmission part drives; a cylinder chamber and slip sheet groove are formed in air cylinder, the exhaust vent in communication with the cylinder chamber, the crankshaft is used for driving the piston to eccentrically rotate in the cylinder chamber, the upper bearing and the lower bearing rotatably supporting the crankshaft,the sliding piece is arranged in the sliding piece groove and can move between an inner limit position and an outer limit position in a reciprocating mode, and the inner end of the sliding piece abuts against the piston; the exhaust valve plate is used for opening and closing the exhaust hole; and the transmission part drives the exhaust valve plate to close the exhaust hole when the sliding sheet moves outwards. According to the compression mechanism, the exhaust valve plate is good in applicability and reliability, low in noise and high in energy efficiency.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compression mechanism, a rotary compressor with the compression mechanism and a refrigeration device. 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. [0003] In the related art, the discharge valve plate of the rotary compressor is usually a reed valve plate with certain elasticity, that is, a certain rigidity. One end of the discharge valve plate is fixed, and the other end is free to open and close the exhaust hole. [0004] The inventor found and realized through research that the great...
