Beschreibung
Zusammenfassung:	The invention relates to an electromagnetic actuator (10) for a valve mechanism, in particular in a common rail system of a motor vehicle, comprising an armature tappet (22) for actuating a valve element (110) located in a channel (100), and comprising a pole core (28), the armature tappet (22) being movable axially along a central axis (X) of the actuator (10) when an excitation coil (52) of an excitation system (50) is energized. The pole core (28) therefore has a tubular shape and has a circumferential flange (28a) in the area of the pole core end facing the channel (100), said flange (28a)extending inward in relation to the central axis (X). 本发明涉及种用于阀机构，尤其是在机动车辆的共轨系统中的电磁致动器(10)，其具有电枢挺杆(22)和极芯(28)，所述电枢挺杆(22)用于致动位于通道(100)中的阀元件(110)，所述电枢挺杆(22)在励磁系统(50)的励磁线圈(52)通电时沿着所述致动器(10)的中心轴线(X)可轴向移动。因此，所述极芯(28)为管状，并且在其面向所述通道(100)的端部的区域中具有周向凸缘(28a)，所述凸缘(28a)相对于所述中心轴线(X)向内延伸。
