Abstract
The invention relates to a fuel injector () for operating with combustible gas. The fuel injector has a plurality of combustible-gas nozzle valve elements (), and the stroke of each of the combustible-gas nozzle valve elements can be controlled by means of a paired hydraulic piston control assembly () of the fuel injector, wherein each piston control assembly is formed by two control chambers () and a piston section () on the combustible-gas nozzle valve element paired with the piston control assembly, said piston section separating the control chambers in such a way that their volumes can be varied, and the fuel injector is designed to control the stroke of the combustible-gas nozzle valve elements in tandem using a 3/2-way valve (), by means of which the hydraulic pressure in one of the two control chambers of the piston control assemblies is controlled.
