Zusammenfassung:Gas valve for injecting gaseous fuels, having a housing (1) in which a pressure chamber (7) fillable with gaseous fuel is provided, and an injector needle (8) being arranged such that it is longitudinally displaceable in said pressure chamber. The injector needle (8) has a longitudinal bore (18) into which gas from the pressure chamber (7) can flow, at one end region of said needle, and which cooperates, by means of a nozzle seat (19) provided at the other end region, with a body seat (21) formed in the housing (1), in order to open and close a flow cross-section. A shoulder (16) is provided on the nozzle needle (8) and cooperates with a sealing disk (15) surrounding the nozzle needle (8) to form a seal seat.
