Abstract

Bei einer Einrichtung zur Belüftung eines Vorratstanks einer mit Druckflüssigkeit arbeitenden Anlage, bei der Änderungen des Niveaus der Flüssigkeit in dem Vorratstank auftreten, wobei letzterer über dem Niveau der Flüssigkeit einen Einlaß (4) für getrocknete Luft aufweist, soll die erforderliche getrocknete Luft ohne Verwendung eines besonderen Lufttrockners bereitgestellt werden.In a device for ventilation of a storage tank with a pressure fluid working system when changing the level of liquid in the storage tank occur, the latter above the level of the liquid an inlet (4) for dried Air has the required dried air without using a special air dryer can be provided.

Dies wird dadurch erreicht, daß der Einlaß über einen Druckregler (2) an eine Druckluftquelle (1) angeschlossen ist.This is achieved in that the inlet via a pressure regulator (2) to a compressed air source (1) connected.

Die in den Vorratstank (5) eintretende Luft ist hierbei dadurch getrocknet, daß die Feuchtigkeit bei der Erzeugung von Druckluft ohnehin ausgefällt wird. Mittels des Druckreglers (2) wird die Druckluft annähernd auf Atmosphärendruck entspannt und in diesem Zustand dem Vorratstank (5) zugeführt, in dem sich ein geringer Überdruck bilden kann.The air entering the storage tank (5) is dried in that the moisture is anyway precipitated when generating compressed air. By means of the pressure regulator (2) the compressed air is expanded to and close to atmospheric pressure Condition supplied to the storage tank (5), in which a slight excess pressure can form.

Das Einströmen entspannter Luft ist damit auf die Menge der aus dem Vorratstank (5) abgezogenen Flüssigkeit begrenzt.

The inflow of relaxed air is thus limited to the amount of liquid withdrawn from the storage tank (5).
