摘要： A fluid compressor has a sealed case, an electric motor section, and a compression section. Both sections are provided in the sealed case, with their axes extending substantially horizontally. The sealed case is filled with lubricant. At the start of the compressor, the rotational speed N of the electric motor section is gradually increased, but maintained at least once at a prescribed value for a predetermined period. At the stop of the compressor, the rotational speed N is gradually decreased, but maintained at least once at a prescribed value for a predetermined period.

摘要： A compressor having a cylinder and a cylindrical rotational body housed within the cylinder. A spiral groove is formed in the outer peripheral surface of the rotational body, and a spiral blade is fitted in the groove so as to be freely retreated in and projected from the groove in the radial direction of the rotational body. The cylinder and the rotational body are rotated relative to each other by a drive mechanism. A fluid to be compressed is introduced into working chambers defined by the blade, the inner peripheral surface of the cylinder and the outer peripheral surface of the rotational body. The fluid is first guided into the first working chamber from a gas suction port, and then into the second and subsequent working chambers successively, whereby the fluid is compressed. An oil supply mechanism supplies pressurized oil to an oil supply hole formed in the rotational body. The oil supply hole communicates with that area of the bottom of the spiral groove, which corresponds to the position where the second and subsequent working chambers begin when the suction stroke of the first working chamber ends. The pressurized oil urges the outer peripheral surface of the blade onto the inner peripheral surface of the cylinder.

摘要： A compressor includes a cylinder, and a rotating body located in the cylinder. A spiral groove is formed on the outer periphery of the rotating body. A spiral blade is fitted in the groove and divides the space between the inner periphery of the cylinder and the outer periphery of the rotating body into operating chambers which have volumes gradually decreasing with distance from one end of the cylinder. A drive motor rotates the cylinder and the rotating body relative to each other. The drive motor includes a cylindrical stator fixed on a closed casing and a rotor mounted on the cylinder and situated inside the stator coaxially, with a motor air gap provided therebetween. A main bearing is engaged with the axial end portion of the cylinder and fixed on the inner wall of the casing by means of a fixing member situated radially more inward than the stator. The main bearing is fixed on the closed casing, with the position of the main bearing adjusted by a master rotor.

摘要： The Oldam-ring of the rotational force transmitting mechanism of a fluid compressor is engaged with the rectangular section formed on the base portion of the main shaft of the rotary rod in the direction perpendicular to the axial direction of the main shaft to achieve an easy assembling of the Oldam-ring to the rectangular section. If the fluid compressor employs a thrust force canceling system wherein the thrust force acting on the rotary rod from the discharge side toward the suction side of a cylinder is canceled by a counter thrust force, the diameter of the main shaft located at the suction side is increased compared with that of the conventional fluid compressor to increase the counter thrust force acting on the edge surface of the main shaft whereby the thrust force can be effectively canceled.
