Beschreibung
Zusammenfassung:	A valve assembly comprises two valves and a single solenoid actuator with only one magnetizing coil that controls both valves. The corresponding magnetic circuit comprises a yoke with only two pole pieces. The valves are arranged concentric to one another. The valve closing element of the outer valve is connected to an armature by means of a sleeve. The cup thus formed receives the armature that is connected to the valve closing element of the inner valve. The pole piece and the armature form a transmission air gap through which the sleeve extends. A coupling air gap is formed between the armatures. The armature and the pole piece form a working air gap. The valves are opened collectively and are able to close independently of one another when the coil is rendered currentless.
