This patent describes a rotary combustion engine having first and second fuel injection nozzles, a fuel supply system comprising: a fuel tank; a supply pump with an inlet communicating with the fuel tank; an engine driver fuel injector pump; and a fuel supply valve comprising: a housing defining a valve bore, a first inlet communicating the valve bore with the injector pump, a second inlet communicating the valve bore with the supply pump, a first outlet communicating the valve bore with the first nozzle and a second outlet communicating the valve bore with the second nozzle; and a valve member movable in the valve bore and cooperating with a wall of the bore to define a first chamber communicated with the first outlet and a second chamber communicated with the second outlet. The valve member is movable in response to fluid pressure in the first chamber from a first position wherein communication between the first inlet and first outlet is closed to a second position where communication between the first inlet and first outlet is open. The valve member forces fuel from the second chamber to the second nozzle via the second outlet as it moves from its first to its second position. The first inlet and the second outlet extending axially from opposite ends of the valve bore, and the first outlet and the second inlet extends radially in the valve housing; and a resilient member biased to urge the valve member to its first position.
