ABSTRACT:
A rotary piston-internal combustion engine has a stationary engine housing with a central axis. A rotor is positioned within the housing and includes a cylinder with first pistons integral with and spaced uniformly apart around the inner surface of the cylinder. The first pistons are sector-shaped. The rotor rotates at a constant velocity. A hub is located within the cylinder coaxial with the central axis and can rotate relative to the cylinder and first pistons. Second pistons are fixed to the hub and each extends radially outwardly from the hub between a pair of adjacent first pistons. Openings extend through the cylinder and are arranged symmetrically relative to axially extending central plane of the first pistons. Seals are provided around the openings between the outside surface of the cylinder and the interior of the housing.
