Abstract

The invention relates to an injector for injecting fuel, preferably for injecting a gaseous fuel, in particular hydrogen, comprising a fuel supply line for introducing a highly pressurized gaseous fuel, an active valve which can be actively shut off and which is designed to close or release at least one passage on a first face of a valve plate in order to selectively release or interrupt a fluidic connection between the fuel supply line and a region which is downstream of the first face of the valve plate, and a passive valve which is arranged downstream of the valve plate and can be passively switched to a closing or releasing state as a result of different pressure ratios upstream and downstream of the passive valve.
