摘要:
A fuel injection valve (1), in particular for the direct injection of fuel into a combustion chamber (18) of an internal combustion engine, has a valve needle (3) which is arranged in a nozzle body (2) and can be actuated by an actuator, and a valve closing body (4) which is operatively connected to the valve needle (3) and, for opening and closing the valve (1), interacts with a valve seat face (6) which is formed on a valve seat body (5), wherein the valve seat body (5) is provided with at least one spray hole (7). The at least one spray hole (7) comprises a first cylindrical section (40) having a fuel inlet opening (36) and a second cylindrical section (41) which is arranged downstream of the first cylindrical section (40) and has a fuel outlet opening (37), wherein the first and the second cylindrical sections (40, 41) do not extend coaxially with respect to one another.
