<p>A compressor includes a cylinder (20), and a rotating body (24) located in the cylinder. A spiral groove (30) is formed on the outer periphery of the rotating body. A spiral blade (32) is fitted in the groove and divides the space between the inner periphery of the cylinder and the outer periphery of the rotating body into operating chambers (34) which have volumes gradually decreasing with distance from one end of the cylinder. When the cylinder and rotating body are relatively rotated, a fluid, introduced into the one end of the cylinder, is transported toward the other end of the cylinder through the operating chambers.</p> |
