Abstract
The disclosure relates to a solenoid valve (1) having a solenoid armature (2) which is operatively connected to a sealing element (5) of the solenoid valve (1) in order to move the same, and an armature opposing piece (16) which engages, at least in certain areas, in a receptacle opening (23) in the solenoid armature (2). There is provision here for the armature opposing piece (16) to be composed of a pole core (19) and an intermediate component (20) which is supported on the pole core (19), wherein only the intermediate component (20) is arranged at least in certain areas in the receptacle opening (23), and at least one venting opening (33, 36), which produces a fluid connection between the receptacle opening (23) and the surroundings of the solenoid armature, is formed in the intermediate component (20). The disclosure also relates to a driver assistance device.
