Abstract
An injector for introducing a gaseous fuel into a combustion chamber. A housing has an outflow opening that can be flowed through by the gaseous fuel. A valve element can be moved between a closed position in which the valve element sits on a valve seat to separate a first housing region from a second housing region and an open position in which the valve element is spaced apart from the valve seat. When moved out of the closed position into the open position, the valve element can be moved into the second housing region. The valve element has a valve body region that is disposed in the second housing region in both the closed position and the open position. The valve body region is domed at least in a partial region of the valve body region and/or is tapered in a direction pointing away from the valve seat.
