Title: DISCHARGE MECHANISM FOR DISPLACEMENT COMPRESSOR
Abstract:
[Problem] To provide a displacement compressor that is provided with a discharge mechanism that is highly efficient and that greatly reduces factors that lower the efficiency of a compression mechanism unit, such as internal leakage of a working gas, excessive compression, recompression loss, and under-compression loss. [Solution] A discharge mechanism configured such that a vertical wall surface of a piston that turns or rotates configures a compression chamber and is used as a valve seat, a tip part of a plate valve, such as a flat-plate gate valve, is in sliding contact with the valve seat, the plate valve is fitted to a valve fitting chamber that is one part of a valve housing chamber that opens at one end into the compression chamber, which is formed in a fixed cylinder, and the plate valve is actuated by an elastic body, etc. or pressure that is introduced into the valve housing chamber and that acts on the plate valve.
