<p>The invention concerns an improvement in the rotary devices disclosed in U.S. Pat. Nos. 3,101,700 and 3,176,908 wherein conjointly rotated bladed and recessed rotors with interengaged blades and recesses, alternately converge and diverge with the blades and end faces on the rotors forming cells between pairs of blades and recesses which are subjected to cyclical intake and compression stages on opposite rotational positions where there are ports to supply and exhaust the cells of fluid. Blades and recesses are shaped to define unsymmetrical volumes which conform closely to one another at the downstream portions of these volumes in relation to the direction of rotation. Upstream portions of the blade and recess at an exhaust station are spaced to form a supplementary exhaust passage from the cell to the exhaust port via the recess.</p> |
