    摘要： A displacement type fluid machine is featured by a low sliding rate and in low vibrations and pulsations but is troubled such that the radial gap in a displacer sliding portion is enlarged by the clearance of a shaft drive system and a rotating moment acting on a displacer so that the internal leakage of a working fluid is increased to lower the performance and the reliability.
    The sliding contact portion between a cylinder (4) and a displacer (5) is made into a predetermined section, and the cylinder and the displacer are so contoured that when they are made concentric, the normal distance in the sliding contact section between the cylinder contour and the displacer contour may be smaller (ε') than that of the remaining section (ε), thereby to decrease the radial gap to lower the internal leakage of the working fluid and to improve the performance and the reliability.

    摘要： A displacement type fluid machine in which a displacer (5) and a cylinder (4) are disposed between end plates (7,8), a space is formed by an inner wall surface of the cylinder and an outer wall surface of the displacer when the center of the displacer is put on the center of the cylinder, and a plurality of spaces (15) is formed when the positional relationship between the displacer and the cylinder is for a gyration, is restrained from deterioration of the efficiency. One of the end plates and a vane (4b) protruding inwardly from the inside surface of the cylinder (4) are fixed to each other so as to restrain the deformation of the vane and decrease the leakage of a working fluid due to the deformation.

    摘要： Side wall surface of an orbiting piston (3) and inner wall surface of a cylinder (2) define therebetween a plurality of working chambers (2a), a space for compressing (discharging) a working fluid is defined between spaces for sucking thereinto the working fluid among the working chambers in any operating condition, and one of end plates, between which the orbiting piston is axially interposed, is formed with suction ports (4a) or discharge ports (5a) while the other of end plates, opposing the end plate formed with the suction or discharge ports, is formed with holes, whereby it is possible to provide a highly efficient and reliable displacement fluid machine which can stabilize pressure balance in the working chambers, and which can greatly reduce fluid loss during discharge stroke.
