摘要： 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.

摘要： A fluid compressor has a piston, the axis of which is vertical. The dimensions of the parts of the compressor are determined such that an upward thrust force acting on the piston is substantially equal to or slightly greater than the total weight of rotational parts including the piston and a cylinder. Specifically, a groove formed in the piston has a pitch decreasing gradually from a lower part to an upper part of the piston, and a diameter (.PHI.D1) of a lower shaft portion of the piston, a diameter (.PHI.D2) of a upper shaft portion of the piston, and an inside diameter (.PHI.Dc) of the cylinder have a relationship, (D1.sup.2 +D2.sup.2)>Dc.sup.2.

摘要： A fluid compressor includes a cylinder and a columnar rotary rod. The rod is arranged in the cylinder so as to extend in the axial direction thereof and be eccentric thereto, and orbitable relative to the cylinder without rotation with respect to the cylinder while part of the rod is in contact with the inner circumferential surface of the cylinder. A spiral groove is formed on the outer circumference of the rod and a spiral blade is fitted in the groove. The space between the outer circumference surface of the rod and the inner circumference surface of the cylinder is divided by the blade into a plurality of operating chambers. The groove has an overall length larger than that of the blade by a predetermined length so that the blade is displaceable relative to the rod in the radial and circumferential directions of the rod without sliding on the inner circumferential of the cylinder.

摘要： A fluid compressor comprises a rotary member, a cylinder, and a closed casing for receiving the rotary member and cylinder. The rotary member and cylinder are relatively turned so that a fluid is drawn into work chambers through a suction port, successively compressed and conveyed toward a discharge port through the work chambers, and discharged outside. The fluid compressor is provided with a control valve means. When pressure in the work chambers exceeds a predetermined value during the compressing process, the control valve releases the pressure through a discharge or suction end of the cylinder, or to the inside of the casing.
