[origin: WO2004033895A1] An injection valve (1) for injecting water, especially into the gas flow of fuel cells, comprising a valve needle (19) with a valve sealing body (21) which is joined on the spray side end thereof and which is embodied on a valve seat body (29), interacting to form a tight seat. Downstream from the tight seat is a spray opening (7).
