    摘要： A conventional displacement type fluid machine is featured by a low sliding rate and in low vibrations and pulsations, but has a problem, 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. To eliminate this problem, 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 than that of the remaining section, 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： Side wall surface of an orbiting piston and inner wall surface of a cylinder define therebetween a plurality of working chambers, 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 or discharge ports 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.

    摘要： A conventional displacement type fluid machine involves a problem that a mechanical friction loss and leakage in sliding portions are large, so that its reliability and performance are poor, and therefore it has not yet been put into practical use. In a displacement type fluid machine, a displacer makes an orbital motion within a cylinder to draw and discharge a working fluid. An compression element includes the displacer of a specified configuration, and the cylinder engaged with this displacer, and a connecting member (rotation prevention member), which abuts against the displacer and the cylinder, is provided inwardly of compression working chambers. With this construction, a rotating moment acting on the displacer can be completely avoided, thereby achieving the high efficiency and the high reliability.

    摘要： In order to make a displacement type compressor be able to reliably start without increasing an outside diameter dimension of the compressor while using a self-start synchronous motor having high energy efficiency, the displacement type compressor according to the invention includes the self-start synchronous motor which starts as an induction-motor and performs synchronous operation by performing synchronization pull-in almost at a synchronous rotational frequency, a compression part having a compression chamber which compresses a working fluid, and a hermetic container which houses the self-start synchronous motor and the compression part. The displacement type compressor is provided with a start load reducing means which reduces a load of the compression part at startup and is placed at the compression part in the hermetic container.
