Abstract
A known fuel injection apparatus, in which fuel and foreign matter outside the fuel injection valve can not flow past the injection valves because a flow opening is disposed between fuel supply conduit and fuel outlet conduit and of which degassing of the fuel takes place before it enters the injection valve, any foreign matter entrained in the fuel will not give rise to malfunctions in a pressure regulation. The penetration of foreign matter into the pressure regulator is prevented by means of an appropriate choice of the dimensions of the flow opening, which is provided between a filter element of the fuel injection valve and the wall of a receiving bore. The fuel injection apparatus is employed in fuel injection systems for mixture compressing internal combustion engines with externally supplied ignition.
