ABSTRACT:
A fluid compressor includes a cylindrical casing, a cylinder arranged in the casing to be rotatable and coaxial with the casing, and a columnar rotary body located in the cylinder and extending in the axial direction of the cylinder. 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 rotary body are relatively rotated by a motor section, 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. The motor section includes an annular stator fixed to the outer circumferential surface of the casing, and a rotor located within the casing and fixed to the outer circumferential surfaces of the cylinder to be coaxial with the casing.
