| 摘要 |
The invention is based on an electromagnetic actuator, especially for activating a valve, having at least one electromagnet (10) that acts on a correspondingly designed armature surface (20) of a moveable armature (22) in a first effective range (12) by way of at least one first conical and/or stepped pole face (18) using a magnetic field (16) generated by at least one coil (14).It is proposed that the electromagnet (10) act on a corresponding armature surface (28) by way of at least a second pole face (26) in at least a second effective range (24).
