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.

摘要： PURPOSE:To unify distribution of the force in the axial direction of a rotary rod provided in a cylinder by providing a sub-bearing on the suction side end and a main bearing on the discharge side end. CONSTITUTION:In a compressor 1, a supporting shaft 12b on the suction side of a rotor 11 is supported with a sub-bearing 9 of short length, and a supporting shaft 12a on the discharge side is supported with a main bearing 8 of long length. Hereby, because the discharge side end can be firmly supported, a load point becomes near on the main bearing 8 side. Consequently, fall down moment of a blade 21 due to pressure difference becomes small and generation of torsion of the rotor 11 can be prevented.

The oil introducing passage 26a is provided with an intermittent feed oil mechanism 40. Hereby, when the pressure in a closed case 2 is raised by rotation of a cylinder 7, lubricating oil 29 is passed through an introducing pipe 28, a through hole 27, and the oil introducing passage 26, passed through the intermittent feed oil mechanism 40 moving up and down accompanied with up and down motion of a blade 21 against the groove 19, and intermittently introduced to the space between the bottom part of the groove 19 and the blade 21. Consequently, appropriate oil feeding can be performed extending over whole circumference of the groove 19 regardless of operating condition.
