ROLLING CYLINDER-TYPE DISPLACEMENT COMPRESSOR

WIPO Patent Application WO/2018/055824

A1

A rolling cylinder-type displacement compressor is provided with: a cylindrical rolling cylinder having a cylinder groove; an orbiting piston having a slide groove; a stationary cylinder having a pin mechanism; a piston orbiting drive source, i.e. a drive source for the orbiting motion of the orbiting piston; a drive transmission section for connecting the orbiting piston and the piston orbiting drive source; a frame through which the drive transmission section passes; and a casing in which the orbiting piston, the rolling cylinder, the stationary cylinder, the piston orbiting drive source and the drive transmission section are housed; wherein the orbiting piston, the rolling cylinder and the stationary cylinder constitute a compression section; the orbiting piston relatively performs a reciprocating motion in the cylinder groove; and cylinder groove outer circumferential walls are provided at both end parts of the reciprocating motion in the cylinder groove. As a result, the seal integrity of an operating chamber in the rolling cylinder-type displacement compressor is improved and high compressor efficiency is achieved.
