Abstract

A shaft 1 supported by bearings 32 in oil sumps 4 is driven by a rotor 14. Air is driven by a turbine 7 through a nacelle 8 where petrol is introduced at 9 into the airstream and the mixture passes through inner induction chamber wall inlet port 10 and rotor inlet port 28 into combustion chamber 24 in the rotor. As the rotor turns, pistons 13 running in a channel 12 isolate the chamber. When electrode 17 passes through anode 33, points 26 are interrupted by eccentric 15 to provide the ignition spark from coil 27. The outlet port 19 of the rotor now comes into line with the exhaust chamber outlet ports 21 allowing discharge from the combustion chamber to drive the rotor, the spent exhaust gasses escaping from the exhaust chamber 22 through exhaust port 34. <IMAGE>

Description

SPECIFICATION Rotor engine This invention relates to an engine driven by a rotor. Most internal combustion engines use pistons, cylinders, cambs, rockers, tappets, sprockets, chains, distributor and oil pump to drive a crankshaft. This invention the rotor engine modifies or discards most of the above and uses a rotor driven by internal combustion to drive a shaft.

According to the present invention one or more combustion chambers are built into a rotor, each chamber has a floor, an inlet port, an outlet port, an electrode through the roof and a curved deflection plate, the rotor is attached to the drive shaft, on the intake side of the rotor there is a stationary induction chamber, from this chamber a petrol air mix is forced by a turbine or other means not shown, through a port in the induction chamber wall, this port is so constructed to contain C shaped "rings" fitted to C shaped "pistons" as they revolve past it.As each revoling inlet port of the rotor comes in line with the inlet port of the induction chamber the combustion chamber is charged with gases, each inlet port of the rotor is separated by a C shaped piston mounted on the side of the rotor, these pistons run in a circular C shaped channel let into the side of the induction chamber wall, the walls of the channel extend past the pistons into grooves let into the rotor wall each piston is fitted with at least one C shaped ring to maintain seal between components.These rings maybe mounted on springs to maintain contact with the channel After the inlet port of the rotor has passed the inlet port of the induction chamber the outlet port of the rotor wich extends into the exhaust chamber wall and is so fitted with vanes or sets or other means not shown to give thrust to the rotor after combustion has take place is just cracking the outlet port of the exhaust chamber, this port extends a goodway round the chamber is stationary and allows a catharine wheel effect.This is where ignition takes place the curved deflection plate in the combustion chamber helps expell remaining gases after initial expansion is spent the exhaust chamber is also the advance and retard mechanism being allowed to revolve backwards or forwards to required position as the speed of the engine requires The ignition system is as follows each combustion chamber has its own electrode mounted through the roof and on the rim of the rotor each chamber has an eccentricity, the points are mounted over the rim and as the rotor turns the eccentricity opens and closes the points wich are connected to the coil wich in turn is connected to an anode mounted astride the rotor.As the rotor revolves each electrode passes under and through the anode recieves the spark and conducts it to the chamber where ignition takes place The shaft is supported on bearings in separate oil sumps, each sump is fitted with oil seals, bearings a filler and a drain plug the channel maybe lubricated by petrol oil mix or oilways let through the inner induction chamber wall.
