A rotary internal combustion engine having a plurality of swinging arms spaced uniformly in a rotor housing and a rotor on a power output shaft adapted to engage the arms in said housing and thereby control the cycle of outward compression and exhaust strokes, and inward power strokes of each of said arms. Each arm includes an outwardly tapered, wedge-shaped horn member engageable within a recess provided in the adjacent engine housing to define an expandable compression chamber between said housing and each arm and to permit said arms to move freely between said inward and outward positions. In the preferred arrangement, the arms and rotor can shift laterally within the housing to positions of equilibrium, and the side portions of said arms and rotor include a plurality of labyrinth grooves in sealing relationship with respect to the rotor housing. Spherical combustion chambers in the housing adjacent the free end of each of said arms communicate with the interior of said housing and are adapted to direct an expanding charge of combustion gases against said arms and the exposed portion of the rotor. Said rotor and arms can be adapted to cause substantially complete combustion of the gas charges within the combustion chambers prior to expansion of the charges in said rotor housing. Exhaust ports provided in said housing selectively exhaust spent combustion gases from the interior of said housing, and a cam startup system is adapted to initiate the cycle of operation for the arms. The rotor may be adapted so that each arm will transmit a plurality of power impulses to the rotor for each complete rotor revolution, and further to overlap the power impulses of adjacent arms during the engine operation.
