Solenoid-valve device e.g. pneumatic valve device used in electric brake system of motor car, has discharge openings sealed by movable armature unit, by pressure-balance in axial direction

摘要

The solenoid-valve device has a movable armature unit (9) for the controlled opening and/or closing of a fluid flow such as compressed air flow formed between an inlet (33) and a valve outlet comprising the discharge openings (29,30). The discharge openings are sealed by movable armature unit, by the pressure-balance in the axial direction. A valve seal (12) and a valve seat (13) are equipped in the movable armature unit.
