    Abstract: The device includes a valve adapted to be closed, when the intake of fuel is reduced, to prevent the entry of burnt gases into the intake pipe. The valve is actuated by a mechanism arranged so that the valve can be fully opened and can shut the intake pipe at a short distance from the peripheral surface of the combustion chamber of the engine. The device is especially useful for rotary piston engines with peripheral ports.

    Abstract: In a rotary-piston, internal combustion engine in which pistons rotate about the axis of a cylindrical casing in circumferentially consecutive relationship in sealing engagement with the casing and move angularly relative to each other in such a manner that each pair of circumferentially consecutive pistons defines a combustion chamber of the engine which expands and contracts during rotation, the casing is formed with an intake port for admitting a fuel mixture to the expanding chambers and with an exhaust port and an auxiliary port juxtaposed circumferentially in the direction of piston movement for releasing the spent fuel mixture as combustion gases from the contracting chambers. A conduit extends from the exhaust port outward of the casing and terminates in a tapering, open nozzle. Another conduit extends from the auxiliary port and has a throat portion spacedly enveloping the nozzle so as to form a jet pump or ejector pump therewith, the pressure of the combustion gas discharged from the nozzle drawing additional gas at lower pressure from the combustion compartment.
