LIGHT WEIGHT INTERNAL COMBUSTION ENGINE WITH STATIONERY PISTONS AND ROTARY VALVES

摘要

A compact light weight engine with few moving parts comprising one or more moving hollow cylinders each divided into two sections by a solid circular disc in the centre, a stationery piston slideably contained at both ends of each cylinder forming two combustion chambers, an igniter device, an exhaust port, a fuel inlet port in the face of each piston, conduit pipes for exhaust and fuel intake connected at one end to the respective ports in the piston face and at the other end to a rotary valve which operates in a timed relationship with the igniter device to allow the fuel mixture in the combustion chamber to be ignited and to provide a connection for the exhaust to the outside causing the hollow cylinder to move in a reciprical motion with respect to the stationery pistons. A rod connecting the moving cylinders to a crankshaft converts the reciprical motion into circular motion which rotates the rotary valve and also provides a rotational power output.
