Description

Es ist bei hydraulischen Anlagen bereits bekannt, die Druckflüssigkeit zur Schonung der bewegten Teile durch ein Filter im Flüssigkeitskreislauf zu reinigen. Dlie bekannte Anordnung eines Filters in der Saugleitung zwischen Flüssigkeitsbehälter und Pumpe hat-, zwar den Vorteil, daß nicht nur die im Kteis umlaufende Flüssigkeit, sondern auch die zur Ergänzung nacJhgefüllte Flüssigkeit gereinigt wird, aber gleichzeitig .den Nachteil einer Drosselung des Saugstromes, weshalb man dazu überging, das Filter für die umlaufende Flüssigkeit in der, Rücklaufleitung zwischen Arbeitszylinder und' Flüssigkeitsbehälter anzuordnen. Hierbei ist jedoch für die Nachfüllung ein zweites Filter vor dem Flüssigkeitsbehälter notwendig.The hydraulic fluid is already known in hydraulic systems to be cleaned by a filter in the fluid circuit to protect the moving parts. The known arrangement of a filter in the suction line between the liquid container and pump has the advantage that not only the liquid circulating in the ice, but also the liquid filled up afterwards is cleaned, but at the same time The disadvantage of throttling the suction flow, which is why the filter for the circulating liquid in the return line between the working cylinder and 'to arrange liquid containers. However, this is a refill second filter necessary in front of the liquid container.

Eirfindungsgemäß wird dieser Nachteil dadurch vermieden, daß für die Flüssigkeitsrückführung vom Arbeitszylinder nach dem Behälter und; für die Nachfüllung ein gemeinsames Filter vorgesehen ist. Erfindungsgemäß kann am Flüssigkeitsbehälter eine Filterkammer vorgesehen sein, in welche einerseits die Rücklaufleitung mündet und in der andererseits eine Nächfüllöffnung vorgesehen ist, die druckdicht verschließbar ist. Erfindungsgemäß steht der Flüssigkeitsbehälter selbst üben- eine Öffnung mit d!er Außenluft in Verbindung.According to the invention, this disadvantage is avoided in that for the Liquid return from the working cylinder to the container and; for refill a common filter is provided. According to the invention, on the liquid container a filter chamber can be provided into which, on the one hand, the return line opens and in which, on the other hand, a subsequent filling opening is provided which can be closed in a pressure-tight manner is. According to the invention, the liquid container itself has an opening the outside air in connection.

Ein Ausführungsbeispiel des Erfindungsgegenstands ist in der Abbildung dargestellt.An embodiment of the subject invention is shown in the figure shown.

Die meist unter Druck vom Arbeitszylinder i zurückfließende Flüssigkeit gelangt über die Rücklaufle:itung 2 durch die E6nlaßöffnung 3 in den abgedichteten Druckraum 4 und wird nach Durchströmen des Filters 5 von dlem Behälterraum 6 als gereinigte Flüssigkeit aufgenommen und durch die Auslaßöffnung 7, die Saugleitung 8 zur Pumpe 9 und D'ruckleitung i o weitergeleitet.The liquid flowing back from the working cylinder i, usually under pressure reaches the sealed one via the return line 2 through the inlet opening 3 Pressure chamber 4 and is after flowing through the filter 5 of the container space 6 as cleaned liquid received and through the outlet opening 7, the suction line 8 forwarded to pump 9 and pressure line i o.

Zum E;in- bzw. Nachfüllen von Flüssigkeit durch das Filter 5 dient eine im Druckraum 4 angeordnete E!infüllöffnung 1a, die bei Inbetriebnahme der Anlage,durch eine Verschraubung druckfest verschlossen wird. Zur Vermeidung eines nachteiligen Unterdruckes in der Saugleitung 8 ist der Behälterraum 6 mit: der Außenluft durch die Belüftungsbohrung ii verbunden.Serves for filling or refilling of liquid through the filter 5 a filling opening 1 a arranged in the pressure chamber 4, which passes through when the system is started up a screw connection is closed pressure-tight. To avoid a disadvantageous Underpressure in the suction line 8 is the container space 6 with: the outside air through the ventilation hole ii connected.
