ABSTRACT:
A fluid displacement machine of the vane type utilizing a cylindrical rotor equipped with one or more tethered sliding vanes wherein the rotor and vane set is rotatably located eccentrically inside an internal conforming casing profile between opposing endplates which combination thereof defines enclosed variable volume compartments. Each vane is fitted on opposite sides with tethers which are pivotally-mounted remotely from the vane tips. The tethers engage, through anti-friction means, circular annuli located within the endplates which are concentric with the hollow casing profile. Two anti-friction tether-to-annuli means are revealed, one in the form of freely-rotating caged roller bearings interposed between the tethers and the respective internal annuli, and the other in the form of tethers equipped with trunnioned bearings which directly engage these internal annular surfaces. Combinations of these anti-friction vane tethering means are also revealed. The vane tethers engage both internal peripheries of the endplate annuli for the purpose of providing positive bi-axial radial vane motion control, and the profile of the casing is defined such that the tips of the positive motion-controlled vanes remain in an exceedingly close yet substantially frictionless sealing relationship with the conforming hollow casing.
