Abstract
A fuel system for a single-cylinder internal combustion gas engine comprising a constant gas pressure governor that is situated in a gas supply line extending to the throat of a venturi carburetor, the gas pressure governor including a diaphragm-operated gas valve that responds to changes in static pressure on the upstream side of the venturi of the carburetor, the governor being adapted to compensate for changes in venturi throat pressure due to the opening and the closing of the intake valve for the single-cylinder engine, whereby the governor tends to maintain a uniform air/fuel ratio throughout a large engine speed range.
