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.

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 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 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 cylinder, and a cylindrical rotating body located in the cylinder. One end of the cylinder is rotatably supported by a first bearing fixed to a case and the other end of the cylinder is slidably fitted with a second bearing. The second bearing is coupled with the first bearing through a support shaft which extends through the cylinder and rotatably supports the rotating body. 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 rotating body are relatively rotated, 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.
