Elastic compaction mechanism of air cylinder and valve plate assembly for refrigeration compressor

The invention discloses an elastic compaction mechanism of an air cylinder and a valve plate assembly for a refrigeration compressor. The mechanism comprises a crankshaft box, a valve plate gasket, a valve plate assembly, an elastic gasket, a screw threaded sleeve, an air cylinder cover gasket, an air cylinder cover, a clamping ring, a gas exhaust silencer and an air absorption silencer; the crankshaft is provided with the air cylinder; the elastic gasket is fixedly connected to the external surface of the valve plate assembly; the outer side of the end part of the air cylinder is provided with external screw threads; the inner side of the end part of the air cylinder is provided with a step hole; the screw threaded sleeve is provided with inner screw threads; after the valve plate gasket, the valve plate assembly and the elastic gasket are guided into the air cylinder step hole, the screw threaded sleeve is compacted externally and is fixedly connected with the air cylinder through the inner screw threads. Through the elastic compaction mechanism provided by the invention, not only can the seal property of the air cylinder and the valve plate assembly be ensured, but also the air cylinder deformation can be reduced effectively, thus the efficiency of the compressor is improved.
