Abstract
A rotary machine has a rotor eccentrically mounted in a casing and having a plurality of vanes connected to oscillating arms via cranks, the cranks having elements pivotally embracing a radial outer end of the arms. The arms can be radial. The rotor has outer axial parts connected to an intermediate part by grooves and rings resisting radial expansion. The rotary machine can be used in a fuel-injected engine for example to derive energy from the difference in air pressure between ambient and the inlet manifold.
Claims19
An internal combustion engine in combination with a rotary positive displacement fluid machine having a rotor eccentrically mounted in a casing with a plurality of vanes defining compartments within the casing which vary in volume as the rotor rotates, the machine being connected to an air inlet manifold of the engine, and to atmoshere, such that the rotor is driven by the pressure difference between ambient air and air at the inlet manifold, the machine being operatively connected to an energy using device.
An engine according to claim in 17, which the means which resist radial movement comprise interengaging formations on the outer parts of the intermediate parts.
