ABSTRACT:
Disclosed are a rotor and a method for manufacturing a rotor for vane-type engines. The rotor includes radial slots which guide vanes extending from spring chambers within the rotor. In the practice of the method: (a) radial bores are provided in rotors to receive springs and serve as spring chambers, (b) longitudinal bores are formed in the rotors parallel to the rotor axes and intersecting the radial bores, (c) springs are placed in the spring chambers (radial bores) to extend into the longitudinal bores, (d) the radial bores are partially closed on the outside by plastic deformation of the rotor material, and (e) radial slots are formed parallel to the rotor axes to intersect the radial bores and permit vanes to extend therethrough.
