ABSTRACT:
A fuel supply arrangement with a fuel metering valve for external-ignition combustion engines, in which continuous fuel addition is provided to the intake pipe. The latter has an air funnel acting jointly with a throttle member coaxially located and axially movable. The throttle member is adjustable against a restoring force via intake pipe underpressure acting in a working chamber which can be vented into atmosphere. The throttle member is actuated by a diaphragm located in a diaphragm housing having one chamber connected to the atmosphere, and having a second chamber at intake pipe underpressure. The second chamber can be vented to atmosphere by a valve having an actuation position which is arbitrarily variable through relative spatial arrangement of a tripping element on the throttle, and the valve. Either the tripping element or the valve is connected rigidly to the axially movable throttle member and the other one of these two elements is connected to an arbitrarily adjustable linkage of the gas pedal. The fuel is under a system pressure which is made variable by a pressure regulator as a function of one or several engine characteristics, and the fuel is delivered to a fuel exit by the fuel metering valve controlled as a function of the position of the throttle member.
