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 fluid compressor includes a rotating body arranged in a cylinder to extend in the axial direction of the cylinder and eccentric thereto. A spiral groove is formed on the outer circumference of the rotating body, and a spiral blade is slidably fitted in the groove. The pitches of the groove is narrowed at a predetermined rate with a distance from a suction-side end of the cylinder to a discharge-side end of the cylider. The groove has an enlarging section which has a start point, a changeover point, and a terminal point. The enlarging section includes a first portion extending from the start point to the changeover point and having a pitch which changes at a rate smaller than the predetermined rate, and a second portion extending from the changeover point to the terminal point and having a pitch which changes at a rate larger than the predetermined rate. The space between the rotating body and the cylinder is divided by the blade into a plurality of operation chambers.

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.

摘要： In a fluid compressor, a cylinder is arranged within a sealed casing. A piston having a spiral groove is placed within the cylinder. The piston is made eccentric to the cylinder such that part of the piston is put in contact with the inner peripheral surface of the cylinder. The piston and the cylinder are rotated relative to each other. A spiral blade is fitted in the spiral groove. The blade is put in contact with the inner peripheral surface of the cylinder, and forming a plurality of working chambers. The blade freely projects from and retreats in the groove. A fluid to be compressed is sucked in the working chambers. The compressed fluid is discharged from a discharge hole portion into the sealed casing. A support mechanism supports the cylinder and one of bearing members for supporting shaft portions of the piston. The support mechanism receives the lubricating oil mixed in the high-pressure compressed fluid discharged from the discharge hole portion. Accordingly, the lubricating oil dispersed from the discharge hole portion is not exhausted to the outside of the sealed casing through an exhaust pipe.
