Abstract

The invention discloses a compression mechanism and a compressor with the same. The compression mechanism comprises an air cylinder, an exhaust hole, a piston, a crankshaft, an upper bearing, a lowerbearing, a slip sheet, an exhaust valve sheet, a lift limiter and a swing rod, when the slip sheet is moved outwards, the swing rod is driven to swing around a pivot so as to enable the swing rod to push the exhaust valve sheet to close the exhaust hole, the swing rod is provided with a valve sheet contact portion and a slip sheet contact portion, the valve sheet contact portion makes contact withthe exhaust valve sheet, the slip sheet contact portion makes contact with the slip sheet, and when the valve sheet contact portion protrudes from the limiting surface of the lift limiter, an included angle between the tangent line of the contact point of the slip sheet and the swing rod and the upper side surface of the slip sheet is beta, and beta is less than or equal to 10 degrees. Accordingto the compression mechanism, the applicability and reliability of the exhaust valve sheet are good, the turn-off noise is low, and the energy efficiency is high.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compression mechanism and a compressor with the compression mechanism. 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. 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. [0003] The inventor found and realized through research that the greater the stiffness of the exhaust valve pl...
