る流体圧縮機。 A spiral groove is provided on the outer periphery of the piston, and a spiral blade is fitted into this spiral groove so that it can move in and out.
This piston is placed eccentrically within the cylinder,
In a fluid compressor that compresses fluid taken in between the blades while transferring it to an axial discharge side of the cylinder by relative movement between the piston and the cylinder, the helical blade and the helical groove are provided. A fluid compressor characterized in that the clearance between the cylinder is larger on the discharge side than on the suction side in the axial direction of the cylinder.
