Abstract:
1. A non-reciprocating and revolving piston engine, comprising: a ring cylinder having a fixed part and coaxially rotating parts; said rotating part further including a pair of coaxial ring gear assemblies revolving at different angular speeds about a common axis passing through a center of said ring cylinder and while completing a single revolution in simultaneous fashion; a coupling and control mechanism mounted on fixed axes for interengaging said ring gear assemblies in order to regulate a differential angular speed established therebetween; at least one revolving piston and at least one further revolving cylinder head mounted to said ring gear assemblies and arranged in opposing and seating fashion within said ring cylinder; an output shaft connected to at least one of said ring gear assemblies for delivering a rotating power output; a single pair of elliptical and eccentrically rotating gears for maintaining a varying speed ratio between said revolving pistons and cylinder heads, said meshing elliptical gears revolving around respective axes that pass through respective geometric focus points of respective pitch ellipses; at least one of said ring gear assemblies being interiorly toothed and connected with a first spur gear with a fixed axis; a coaxially positioned gear rigidly connected to said first spur gear and operative to drive a second spur gear and to which is rigidly connected a selected one of said elliptical gears, a rotating axis of said second spur gear passing through a focus of a pitch ellipse of said selected elliptical gear; said selected elliptical gear driving said other elliptical gear which has its fixed axis of rotation passing through the focus of the pitch ellipse, said other selected elliptical gear in turn being rigidly connected to a third spur gear in turn driving said rotating part of said ring cylinder.
