Abstract
The present invention discloses a rotary engine having a cylindrical stator with a plurality of radially arranged cylinders each having a piston, a shaft is rotatably mounted co-incident with the longitudinal stator axis, and an orbitor having a cylindrical interior encompasses the stator. Sequentially phased reciprocation of the pistons is transmitted to the orbitor which orbits about the shaft axis in a "polishing-cloth" motion without rotation or revolution of the orbitor. A gear mechanism converts the orbital motion of the orbitor to rotation of the shaft.
Claims4
An internal combustion engine comprising a stator, a shaft rotatably mounted in and supported by the stator, a plurality of cylinders mounted on the stator with their axes radially arranged relative to the shaft axis and angularly spaced around the shaft axis, a piston reciprocately mounted in each cylinder, an orbitor fixed to the shaft, a gear fixed to the shaft, a toothed bore in the stator larger in diameter than said gear, a track on the stator concentric with the toothed bore, a roller mounted on the orbitor with the axis of rotation of the roller eccentric to but parallel with the shaft axis and with the roller engaging said track to maintain meshing engagement between some teeth of the gear and some teeth of said toothed bore, a follower on each piston, curved support surface means on the orbitor concentric with the shaft axis and resilient means to urge the followers into contact with said support surface means.
