ABSTRACT:
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.
