Abstract
A fluid compressor comprises a cylinder and a columnar rotating body synchronously rotated by a drive means, The rotational movement of the cylinder and the columnar rotating body is supported by a pair of roller bearing assemblies. A clearance is provided between the roller bearing assemblies and bearing members to allow fluid from the compression chambers to pass into an interior of the casing of the compressor. With the arrangement of roller bearing assemblies at the ends of cylinder and columnar rotational body combinations, a large diameter of the cylinder is possible and thus high compression efficiency of the fluid compressor is achieved.
