Patent-Anspruch:Patent claim: Bei Druckminderern behufs Ermöglichung völliger Absperrung die Anordnung einer geschlossenen Kammer e und eines hohlen, mit Ausgangsöffnungen f und Absperrkegel g versehenen entlasteten Doppelkolbens c, dessen Stellung durch den vom Minderdruck beeinflufsten, von aufsen belasteten Kolben i geregelt wird, in solcher Weise, dafs der für die Entlastung des Doppelkolbens nöthige zweite Weg für die zugeführte Druckflüssigkeit vom Hochdruckraum k aus durch die Kammer e, den hohlen Doppelkolben und die Oeffnungen f führt, wobei durch Niederdrücken von g auf seinen Sitz der Weg von k zum Minderdruckraum d abgesperrt werden kann.In the case of pressure reducers to enable complete shut-off, the arrangement of a closed chamber e and a hollow, relieved double piston c provided with outlet openings f and shut-off cone g , the position of which is regulated by the externally loaded piston i, influenced by the reduced pressure, in such a way that the for the relief of the double piston necessary second path for the supplied pressure fluid leads from the high pressure chamber k through the chamber e, the hollow double piston and the openings f , whereby the path from k to the lower pressure chamber d can be blocked by pressing g on its seat.
