VALVE ASSEMBLY IN A PISTON TYPE COMPRESSOR

摘要

A valve assembly in a piston type refrigerant compressor is disclosed. The valve assembly includes a retainer formed integrally with a gasket plate for restricting the opening of a discharge reed valve of the compressor, and having on opposite sides at the distal portion thereof stay portions integral with the gasket plate for rigidly holding the retainer. According to the present invention, provision is made to guide some part of the refrigerant gas compressed in a cylinder bore to be discharged into a discharge chamber in such a way that the influence of the discharge gas pressure on the retainer at its distal end is reduced. In some embodiments of the invention, this is accomplished by guiding and allowing part of the gas to flow toward the proximal portion of the retainer to discharge the gas.
