Abstract:
An engine fuel apparatus comprising:a body having a fuel and air mixing passage through which a fuel and air mixture is delivered to an engine and a fuel outlet passage through which liquid fuel is discharged to support engine operation; a throttle valve carried by the body having a shaft and a valve head carried by the shaft, disposed in the fuel and air mixing passage and rotatable between idle and wide open positions; a first valve carried by the body in communication with the fuel and air mixing passage for movement between an open position permitting fuel flow to the fuel and air mixing passage and a closed position at least partially restricting fuel flow to the fuel and air mixing passage to control the amount of fuel delivered to the fuel and air mixing passage; a second valve carried by the body in communication with the fuel outlet passage for movement between an open position permitting fuel flow to the fuel outlet passage and a closed position at least partially restricting fuel flow to the fuel outlet passage to control the amount of fuel discharged from the fuel outlet passage; and a mechanical linkage which selectively moves both the first valve and second valve between their open and closed positions in response to movement of the throttle valve between its idle and wide open positions to control the fuel delivered to both the fuel and air mixing passage and the fuel outlet passage as a function of the throttle valve position.
