Abstract
A carburetor having a fuel reservoir containing fuel therein has a fuel inlet valve for controlling the admission of fuel into the reservoir, a float urges the inlet valve shut when the fuel level within the reservoir attains a preselected level, an idle fuel passage including a fluid restrictor communicates between the fuel within the reservoir and the carburetor induction passage, a conduit generally in parallel with the fuel inlet valve has one end communicating with the reservoir and an other end effective for communicating with a source of fuel, an auxiliary valve is situated in series with the fuel inlet passage upstream of the fuel inlet valve, a relatively low flow-rate valve is serially situated in the parallel conduit, and a fuel level indicator is responsive to the actual level of the fuel in the reservoir, the auxiliary valve is opened to fill the reservoir through the fuel inlet valve to a preselected level and have the float shut the inlet valve after which the auxiliary valve is closed, and then the low flow-rate valve supplies fuel to the reservoir at a rate of flow equal to the specified rate of flow to be discharged to the engine and the flow area of the fluid restrictor is adjusted so that the elevational level of the fuel in the reservoir is constant indicating that the flow discharge from the carburetor is exactly the same as the flow rate of fuel entering the carburetor.
