  • Known solenoid valves as described for example in DE20122909U1, generally have a housing with an internal chamber in which a closing body between a closed position, in which it seals on a valve seat, and an open position, in which it is spaced from the valve seat under the influence of an outside of the chamber arranged electromagnet is movable.
