Abstract

A fuel injection nozzle is proposed having two nozzle needles in which the control of the fuel delivered via an inflow line is effected by means of a slide valve embodied as a 3-way valve, which in a preferred embodiment of the invention is simultaneously embodied as a 3-position valve and permits not only the alternative exertion of the fuel pressure upon one of the nozzle needles but also a common pressure exertion of both nozzle needles.
