ABSTRACT:
A fluid compressor includes cylinder, and a cylindrical rotating body located in the cylinder. One end of the cylinder is rotatably supported by a first bearing fixed to a case and the other end of the cylinder is slidably fitted with a second bearing. The second bearing is coupled with the first bearing through a support shaft which extends through the cylinder and rotatably supports the rotating body. A spiral groove is formed on the outer circumferential surface of the rotating body. A spiral blade is fitted into the groove and divides the space between the inner circumferential surface and the outer circumferential surface into a plurality of operating chambers which have volumes gradually decreasing with a 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 transferred toward the other end of the cylinder through the operating chambers and compressed during the transfer.
