Abstract: A valve nozzle for introducing a flowable liquid into a mixing chamber through which flows a gas includes a nozzle head having defined therein the mixing chamber and having a gas delivery conduit which communicates with the mixing chamber, the mixing chamber having at least one nozzle opening through which a mixture of the gas and the flowable liquid pass from the nozzle head; driving device for opening and closing the at least one nozzle opening; closing spring connected to the driving device; an actuating device connected to the closing spring; a closure body which is disposed on the outflow side of the at least one nozzle opening, which is supported on the actuating device, and which is axially movable; a distribution chamber which discharges into the mixing chamber and has a valve seat for the closure body so that the interstice between the valve seat and the closure body, in an open position of the closure body, forms the at least one nozzle opening; a delivery conduit for the flowable liquid which terminates in a calibrated inlet bore that discharges into the distribution chamber.

Abstract: A device for the combined blowoff of fuel and air for direct fuel injection systems in internal combustion engines. The device includes a housing having a fuel connection and an air connection as well as a blowoff aperture connected with both connections and closable by electromagnetically operable valves. A fuel valve is arranged behind an air valve, also opening toward said blowoff side of said blowoff aperture. Both valves are arranged concentrically relative to each other and capable of resting with their valve seats sealing against the housing.
