摘要： A solenoid valve is described, its armature having a part that is slidingly displaceable on the foundation bolt and is movable between two stops of the foundation bolt against the tension force of a restoring spring. When the armature strikes the valve seat of the solenoid valve, the slidingly displaceable part moves further under the influence of its inertial mass on the foundation bolt in the closing direction against the tension force of the restoring spring, until it strikes the second stop of the foundation bolt. The resulting transfer of momentum to the foundation bolt reduces impact of the armature on the valve seat and causes the armature to more quickly reach a defined rest position in which the solenoid valve is closed.
