摘要： PROBLEM TO BE SOLVED: To improve the compression efficiency in a fluid compressor comprising a vertical type helical blade compressing mechanism part, by installing a suction part of the fluid to be compressed, at a lower part of a rotator forming the compressing mechanism part, and dipping a thrust face which is a lower side edge face, into the lubricating oil supplied from an oil storing part. SOLUTION: When a crank shaft 9 is rotated and driven integrally with a rotor 30, a roller 11 is revolved, and a coolant gas of low pressure is sucked from a suction pipe 17, and is temporarily stored in a recessed part 19 of a roller 11 just before it is guided to a compression chamber 15 from the gas suction part 18. Then the coolant gas is guided to a compression chamber 16 at a suction part A side, and then the volume of the compression chamber 16 is gradually reduced by a blade 15, so that the coolant gas is compressed during the time when it is successively transferred to the compression chamber, to be discharged through a discharge hole 20 and a discharge pipe 21. On this occasion, a thrust face 11b which is a lower edge face of the roller 11 is dipped in the lubricating oil guided through an oil conducting hole 23, so that the sliding resistance does not exist, and the smooth motion of the roller 11 can be assured.

摘要： PURPOSE: To highly precisely secure control of dimension in which a piston and an Oldham's ring can move in the shaft direction by making dimension in which a rotor and the Oldham's ring can move in the shaft direction smaller than dimension in which the rotor and the Oldham's ring can move between a pair of bearing tools. CONSTITUTION: A cylinder 4 consisting of a hollow cylindrical body both ends of which are open is provided on a compression mechanism part 2, and a piston 7 is eccentrically arranged as a rotor in the cylinder 4. Dimension (a) in which the piston 7 and an Oldham's ring 27 can move in the shaft direction against first and second cylinder bearings 16, 17 by engaging the piston 7 and the Oldham's ring 27 of roughly the same outline dimension as the piston 7 is set smaller than dimension (b) in which the piston 7 and the Oldham's ring 27 can move in the shaft direction between main cylinder bearings 12, 13. Consequently, it is possible to highly precisely control dimension in which the piston 7 and the Oldham's ring 27 can move in the shaft direction.
