Turbolader (1)- mit einem Verdichter (2),- mit einer mit dem Verdichter (2) über eine Welle (3) verbundenen Turbine (4),* die einen Abgaseinlass (5) und einen Abgasauslass (7) aufweist- mit einer Bypassleitung (6),* die unter Umgehung der Turbine (4) vom Abgaseinlass (5) abzweigt und zum Abgasauslass (7) führt,und* in der ein Absperrorgan (8) angeordnet ist, das von einem Stellglied (9) betätigbar ist, wobei- das Stellglied als elektromagnetischer Aktuator (9; 22) ausgebildet ist,dadurch gekennzeichnet,dass der Aktuator (9; 22) einen Stahlgehäusezylinder (18; 25) und einen Aluminiumzylinder (19; 26) umfasst, der innerhalb des Stahlgehäusezylinders (18; 25) angeordnet ist. The turbocharger (1) has a turbine (4) connected with a compressor (2) by a shaft (3), where the turbine has an exhaust inlet (5) and an exhaust gas outlet (7). A bypass conduit (6) diverts under branching of the turbine from the exhaust inlet and guides to the exhaust gas outlet. A shut-off valve (8) is arranged in the conduit, where the valve is actuated by an actuator (9). The actuator is designed as an electromagnetic actuator. The actuator has a main spool, a starting spool and a circular permanent magnet which is arranged between the main spool and the starting spool.
