Title: Rotary internal combustion engine having rotary valve means for fuel and air introduction

Abstract: A rotary internal combustion engine comprising an engine frame having a rotor rotatably mounted therein which has a plurality of radially spaced cylinders mounted thereon. The free floating piston is slidably mounted in each of the cylinders with the head of the piston being positioned towards the center of the rotor with a roller mounted in the skirt end thereof which rides against a circular cam. A drive shaft is secured to the rotor and it rotatably extends outwardly from one side of the engine frame. A core means extends into the engine frame opposite of the drive shaft and has air and fuel passageways formed therein which are in communication with a source of air and fuel respectively. The inner end of the core means communicates with a rotary valve which is in communication with air and fuel passageways formed in the rotor which are in communication with the cylinders. Each of the cylinders is provided with a plurality of radially spaced openings formed therein. A portion of the cylinder openings are in communication with the air passageway formed in the rotary valve while a portion of the cylinder openings are in communication with the fuel passageway formed in the rotary valve means. The remaining cylinder openings are in communication with an exhaust manifold so that the exhaust gases may be expelled from the interior of the cylinder outwardly through the center of the drive shaft. Each of the cylinders is provided with a plurality of small combustion reservoir cavities formed therein near the top portion thereof which permits more efficient and accurate timing.
