The invention relates to an injector (24) for feeding a gaseous fuel into a combustion chamber (22), having a housing (26) through which the fuel can flow, having an outflow opening (28) through which the fuel can flow, via which the fuel can be discharged from the housing (26) for feeding the fuel into the combustion chamber (22), and having a valve seat (30) and a valve element (38), the valve member is movable between a closed position and an open position. In the closed position, the valve element (38) is seated on the valve seat (30) such that a first housing region (42) through which the fuel can flow and a second housing region (44) through which the fuel can flow are separated from each other. In the open position, the housing regions (42, 44) are fluidically connected such that fuel flowing through the housing regions (42, 44) can be discharged from the housing (26) via the outflow opening (28). The valve element (38) opens outwards and comprises a raised and/or constricted valve body (50) which is a
