US Patent:

41749308, Nov 20, 1979

Filed:

Nov 21, 1977

Appl. No.:

5/853100

Inventors:

Chester A. Posson - Rolling Meadows IL

International Classification:

F02B 5300

US Classification:

418 36

Abstract:

A rotary engine is disclosed having two pairs of blade pistons each of which is carried on a separate one of a pair of coaxial shafts facilitating relative rotational movement between the blade pistons within an annular chamber. The coaxial shafts are cooperative with a main power shaft through a motion translation mechanism which controls movement of the pistons about their common axis so that the pistons have uniform alternating accelerating and retarding rotary movements facilitating cyclical movement of the pairs of pistons to establish intake, compression, ignition and exhaust cycles at predetermined arcuate positions about the annular chamber.

International Classification:

F02B 5300

US Classification:

123205

Abstract:

A rotary engine is disclosed having a plurality of rotor blades spaced around an annular chamber and dividing the chamber into separate engine chambers. The rotor blades drive two output shafts which are coupled by a transmission means to provide a single rotational output. The transmission means alternately drives selected of the rotor blades at an increased forward rotational speed while simultaneously driving the other rotor blades in a reverse direction so the latter remain stationary relative to the housing. The alternate driving of the rotor blades varies the volume of the engine chambers formed by the blades to provide expansion and contraction of the engine chambers.
