HELICAL COMPRESSOR, MANUFACTURE THEREOF, AND HELICAL BLADE TYPE COMPRESSOR USING HELICAL BLADE

摘要

PROBLEM TO BE SOLVED: To improve flexibility, sealing property, sliding property, environment property, and durability by arranging a helical blade of a helical blade type compressor provided with a low frictional part, and an elastic part having high elasticity, and forming a surface layer part for forming a blade surface as a low frictional part, and forming a blade inner part as an elastic part.;SOLUTION: A helical blade type compressor is provided with a helical blade type compression mechanism part in an enclosed case, and an electric motor part arranged on an outer peripheral side of the compression mechanism, in a concentric circle shape, and the compression mechanism part is driven by the electric motor part. The compression mechanical part is provided with a multi stage compression chamber 11 formed by coming in and out of a helical blade 8 into/from a helical groove 7 while a cylindrical cylinder 5 and a piston roller 6 arranged on an eccentric position of an inside of the cylindrical cylinder 5 are integratedly rotated. In this case, the helical blade 8 is composed of a blade surface layer part 15 as a low frictional member made of ethylene tetrafluoride resin and the like having oil containing property, and a blade inner part 16 which consists of a elastic member of three layers.;COPYRIGHT: (C)2000,JPO
