摘要： Actuators for valves in internal combustion engines comprising an electromagnet (10), an actuator housing (12) in which the electromagnet (10) is arranged, and a yoke plate (30) of the electromagnet (10), which is arranged on an axial end of the actuator housing (12), are known. However, these exhibit leaks along the gap between the injection moulded plastic housing and the yoke plate. To prevent this, according to the invention a seal ring (42) is arranged on the axial side of the yoke plate (30) facing the electromagnet (10), which seal ring is pressed axially in the direction toward the yoke plate (30) via a clamping plate (44; 48).

摘要： Actuators for valves in internal combustion engines are known, comprising an electric drive unit (12), a housing (14) in the interior (16) of which the drive unit (12) is arranged, at least one aeration opening (56) in the housing (14), and a plug (46) via which the drive unit (12) can be electrically connected to a voltage source. Said actuators are frequently insufficiently protected from an intrusion of spray water or cannot be sufficiently aerated or de-aerated. In order to achieve a seal again spray water with a simultaneously good aeration of the interior, the aeration opening (56) in the housing (14) is closed by a fine-pore membrane (62).
