Abstract

In a solenoid valve for a hydraulic braking system, a valve body has a receiving region which at least partially accommodates a guide assembly, the valve armature running axially through at least one through-opening of the guide assembly. A mechanical detent device is formed between the guide assembly and the valve armature, the detent device releasing the valve armature when the latter is in a de-energised closed position, such that the restoring spring drives the valve armature and pushes the closing element sealingly into the valve seat to produce a sealing function, and said detent device fixes the valve armature in a de-energised open position against the force of the restoring spring in an axial detent position, such that the closing element is raised from the valve seat.
