摘要： A compressor includes a cylinder, and a rotary rod arranged in the cylinder. A spiral groove is formed on the outer periphery of the rotary rod. The spiral groove is formed such that its depth direction extending from the bottom of the groove to the opening thereof is inclined at a predetermined angle toward a discharge side of the cylinder with respect to the axis of the rotary rod. Pitches of the spiral groove are gradually narrowed with distance from the suction-side end of the cylinder. A spiral blade is fitted in the spiral groove to be slidable in the depth direction. The blade divides a space between the outer periphery of the rotary rod and the inner surface of the cylinder into a plurality of working chambers. When the cylinder and rotary rod are relatively rotated, a fluid, introduced into the suction-side end of the cylinder, is transported toward the discharge-side end of the cylinder through the working chambers.

摘要： 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.

摘要： A compressor includes a closed casing having a suction chamber and a discharge chamber. A rotating member is arranged in the casing and has a spiral bore extending along the axis of rotation of the rotating member. The bore has first and second end openings communicating with the suction and discharge chambers, respectively. A spiral internal member is inserted into the bore to rotate relative to the rotating member as the rotating member is rotated by an electric motor section in the casing. In conjunction with an inner surface of the bore, the internal member defines a plurality of closed spaces moving from the first end opening to the second end opening. A fluid in the suction chamber is transported from the first end opening to the second end opening while confined within the spaces, and is then discharged into the discharge chamber. The discharge of the fluid is controlled by a valve mechanism.

摘要： A compressor includes a casing wherein a compression section and a drive section are contained. The compression section has a cylinder, a rotary rod eccentrically arranged in the cylinder and rotatable relative to the cylinder, and first and second bearings rotatably supporting suction- and discharge-side ends of the cylinder. A space defined between the inner circumferential surface of the cylinder and the outer circumferential surface of the rod is divided into a plurality of operating chambers by a spiral blade mounted on the rod. A fluid introduced into the suction-side end of the cylinder is transferred to the discharge-side end of the cylinder through the operating chamber while it is compressed. The compressed fluid is discharged into the casing. The pressure of the introduced fluid is applied to a discharge-side end of the rod, and the pressure of the compressed fluid is applied to a suction-side end of the rod.
