Abstract: The present invention relates to a fuel injector for fuel injection systems of internal combustion engines, including, among others, an actuator (10, 11, 12) and a movable valve part (5, 7) cooperating with a fixed valve-seat (22) formed at a valve-seat member (16), to open and close the valve. Arranged downstream from the valve seat (22) is a disk-shaped swirl element (25) which is provided with at least one inlet region (27) and also at least one outlet opening (29), and which includes at least one swirl channel (28) upstream from the outlet opening (29). The inlet region (27) in the swirl element (25) receives a central inflow. All swirl channels (28) originate from here, so that the fuel, which flows through the swirl channels (28) exclusively from the inside towards the outside in the radial direction, is imparted with a swirl component.

Abstract: A fuel injector (1), especially a fuel injector (1) for directly injecting fuel into a combustion chamber of an internal combustion engine, includes a preferably disk-shaped valve-closure member (8) which forms a sealing seat with a sealing body (10). The fuel injector (1) is opened and closed by rotating the valve-closure member, using an electric motor (2).
