    摘要: A roller is provided in a hollow cylinder and is eccentric with the axis of the cylinder. A helical groove is made in the outer circumferential surface of the roller. A blade is fitted in the helical groove and can move into and from the helical groove. The blade forms a plurality of compression chambers between the cylinder and the roller. Coolant gas is gradually compressed in the compression chambers. The helical groove has two opposing sides. One side positioned at a high-pressure compression chamber is inclined to the other side such that the groove gradually opens toward the outer circumferential surface of the roller.
