ABSTRACT:
This invention is an engine for operating on internal combustion, steam or compressed gases or as a pump and has one or more cam faced pistons which move along a cylinder tube and open and close valve valves which separate lengths of the cylinder into chambers. Gate valves for the tube have semicircular concave ends to radius of the tube to seal against tapered convex ends of the piston while passing the piston between chambers. The internal combustion engine has a compression-combustion chamber inside the piston, jet nozzle port therefrom to the rear chamber sealed by the gate valve to provide back pressure to drive the engine, thus extending the efficiency of the engine over a wider speed range to eliminate transmission gearing.
The engine can be made linear or rotary, and the rotary engine can have high torque because the tubular cylinder is around the periphery of a disc to be driven. The engine utilizes impulse reaction, expansion, back pressure and jet exhaust all combined to increase efficiency, deliver near continuous torque along the cylinder, and can be made self starting.
