A self regulating and balancing gas valve is located in a fuel supplu line between a gaseous fuel storage container and the intake manifold of a fuel burning engine. The valve includes a diaphragm which defines one wall of a chamber into which a gas inlet leads out from which a gas outlet leads. An accelerator pedal controlled valve is positioned in the outlet, for controlling suction and the flow rate of gaseous fuel from the chamber in response to the position of the accelerator pedal. An inlet valve means is provided to control the flow of gaseous fuel through the inlet into the chamber. This valve means includes a control means interconnected between the diaphragm and the inlet valve means, operable to open or increase the size of the inlet in response to inward movement of the diaphragm and to decrease or close the inlet in response to outward movement of the diaphragm. The metered gaseous fuel is delivered into the intake manifold closely adjacent to where the fuel mixture from the gasoline carburator discharges into the manifold. The gaseous fuel contacts incoming air at this location and mixes with it in the intake manifold. |
