摘要： A fluid compressor comprising a helical blade type compression mechanism that includes a cylinder, a roller arranged inside the cylinder and a helical blade interposed between the roller and the cylinder. The blade, the roller and the cylinder are formed of materials whose coefficients of thermal expansion satisfy relationships: Blade>Roller>Cylinder. According to this invention, pressure release can be easily performed in the case where the liquid flows back or under a low-temperature condition as at the time of actuation. In addition, the compression performance can be improved under a high-temperature condition during operation.

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 having first and second discharge ends, in which a rotating rod is rotatably arranged. First and second spiral grooves are formed on the outer circumference of the rod, and first and second spiral blades are fitted into the grooves. The first groove has a first starting end located in the middle portion of the rod, and extends from the starting end toward the first discharge end. The second groove has a second starting end located in the middle portion of the rod, and extends from the second starting end toward the second discharge end. The first and second starting ends are set apart from each other by a certain angle in the circumferential direction of the rod. Operating fluid is introduced into the middle portion in the cylinder, and fed to the first and second discharge ends of the cylinder through operating chambers defined by the first and second blades in the cylinder.

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.
