Abstract
An intake passage for an internal combustion engine is provided on the downstream side of a throttle valve with a fuel injection nozzle connected through a fuel passage to a fuel pump and is additionally provided on the upstream side thereof with an air metering valve arranged to be turned towards its opening side according to increase in an intake negative pressure, and the fuel passage is provided with a fuel metering valve interposed therein. The fuel metering valve is formed into a slidable type spool valve, a valve body thereof is disposed in parallel with a valve body of the air metering valve and a lever is swingably supported at its middle portion and is in engagement at its one end with a cam mounted on a turning shaft of the air metering valve and is in engagement at its other end with a valve rod projecting from one end portion of the fuel metering valve.
