ABSTRACT:
A rotary steam engine has a working chamber (14), with first and second cylindrical rotors (1,2) mounted in overlapping cylindrical chamber portions (26, 27) for rotation about respective parallel axes (24, 25), connected by gears (18) for synchronized rotation. The first rotor (1) has at least one pusher (21) extending radially outward of the first rotor's circumferential surface, and the second rotor's circumferential surface has a corresponding at least one indenture (22) shaped to receive the pusher (21) during rotation of the two rotors (1, 2 ) . Side plates (4) attached to the first rotor (1) for rotation with the first rotor (1), press against spring-loaded seals (34) and the second rotor (2) to provide improved sealing with minimum wear.
