ABSTRACT:
A fuel control means is provided for supplying vaporized fuel to burners such as gasoline lanterns and camp stoves. The control means includes fuel and pressurized air conduits which extend from the fuel tank of the burner toward the burning means and which provide inlet and outlet orifices. Inlet orifice restricting means and outlet orifice restricting or cleaning means are movably mounted within the conduit, and a valve member is movably mounted within the conduit to open and close the fuel passage therethrough. A single control member is operatively connected to each of the orifice restricting means and to the valve member, and the single control member is movable between a first position in which the outlet restricting means is positioned in the outlet orifice to clean the same, a second position in which the valve member is maintained open and the inlet restricting means is positioned in the inlet orifice to permit air mixed with fuel to flow from the tank through the conduit, and a third position in which the valve member is maintained open and the inlet restricting means is positioned out of the fuel inlet to prevent air from flowing into the conduit with the fuel.
