The present invention relates to a device for direct injection of a gaseous fuel, in particular hydrogen, which device comprises: a pressure-control unit which is designed to convert a supplied variable pressure level of the gaseous fuel into a fixed constant output pressure level; a distributor unit which is connected to at least one injector for direct injection of the gaseous fuel, which has been guided through the pressure-control unit, into a combustion chamber; and a fluid connection between the pressure-control unit and the distributor unit in order to guide the gaseous fuel at a constant output pressure downstream towards the distributor unit. The device is characterized in that a flow-control valve is disposed along the fluid connection and designed to adjust the constant output pressure level of the gaseous fuel to a desired target pressure not exceeding the output pressure level.
