Abstract:
A rotary machine having two rotors mounted for rotation on parallel axes, each in one of two intersecting cylindrical chambers, a first of the rotors having a hub and a flap extending radially from the hub into close proximity with, but not into contact with, the cylindrical wall of the respective chamber, and the second of the rotors having a hub and a radial recess which accommodates the flap as the rotors rotate, the rotors being linked to one another so that they rotate at the same angular speed but in opposite angular directions, the flap dividing the chamber in which the first rotor rotates into two volumes, one either side of the flap, and the first rotor including an inlet for working fluid, the inlet communicating with a radial passage which extends from a hub of the first rotor into the flap, and ends in a plurality of outlets, all on the same side of the flap, and all in communication with the same radial passage through which incoming working fluid can be directed into a volume on one side of the rotor.
