ELECTROMAGNETIC ACTUATORS, IN PARTICULAR FOR DRIVING A PUMP

摘要

The invention relates to an electromagnetic actuator (40), in particular for operating a pump (33) for pumping a liquid (29) from a tank (35) to an exhaust gas system (10). Means for damping sound emissions are provided in the region of at least one element of the electromagnetic actuator (40), and the means are disposed in the region of an armature (58) and/or a stop (49) of the actuator (40) interacting with the armature (48) and/or between the armature (58) and the stop (49).
