Abstract

See full text

A rotary engine is provided to produce torque. The engine includes a planar housing, an elongated rotor, a pair of double-concave blades, fore and aft cover plates, and a gear box. The housing has a circular center cavity, and a pair of circular lateral cavities overlapping the center cavity and disposed along a longitudinal axis. The rotor is disposed on a rotor shaft along a rotation axis perpendicular to the longitudinal axis within the center cavity. The blades flank the rotor and are disposed within their corresponding lateral cavity and turn on corresponding blade shafts parallel to the rotor shaft. The blades flank the rotor disposed within their corresponding lateral cavity and turn on corresponding blade shafts parallel to the rotor shaft. The fore and aft cover plates flank the housing along the rotation axis to cover the center and lateral cavities. The gear box is disposed on the aft cover plate and has a rotor gear wheel with adjacent corresponding blade gear wheels. The rotor gear wheel turns with the rotor shaft while engaging both blade gear wheels along their peripheries. The blade gear wheels turn with the corresponding blade shafts. The blades turn opposite to the rotor.
