Abstract
A fuel injection valve is proposed for fuel injection systems of internal combustion engines, which serves to supply fuel into the intake tubes of the engine. The injection valve includes a movable valve element which cooperates with a fixed valve seat. Downstream of the valve seat a bore is provided in the valve body. A charge controlling device in the form of an insert having a section having axially extending flutes thereon is pressed into the bore. The insert has a section on its end away from the fixed valve seat that functions as a metering section. The metering section has a diameter smaller than the internal diameter of the bore, with the metering of fuel taking place in the space thus provided. A diversion means downstream of the charge controlling device serves to divert fuel flow from a valve in a radially extending fan-type spray into an intake tube.
