Dmckmittelbetätigte Einrichtung
Stand der Technik Pressure medium operated device
State of the art
Die Erfindung geht aus von einer druckmittelbetätigten Einrichtung nach der Gattung des Hauptanspruchs. Derartige bekannte Einrichtungen haben den Nachteil, daß Leckverluste nicht schnell genug festgestellt werden können, so daß unter Umständen Schaden an der Einrichtung entstehen.The invention is based on a pressure medium-operated device according to the type of the main claim. Such known devices have the disadvantage that leakages cannot be detected quickly enough, so that damage to the device may occur.
Vorteile der ErfindungAdvantages of the invention
Die druckmittelbetätigte Einrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß Leckageschäden sofort und automatich festgestellt und signalisiert werden.The pressure medium-operated device with the characteristic features of the main claim has the advantage that leakage damage is immediately and automatically detected and signaled.
Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen. ZeichnungFurther advantages of the invention emerge from the subclaims. Drawing
Ein Ausführungsbeispiel der Erfindung ist in der nachfolgenden Beschreibung und Zeichnung näher erläutert. Letztere zeigt einen Längsschnitt durch eine druckmittelbetätigte Einrichtung.An embodiment of the invention is explained in more detail in the following description and drawing. The latter shows a longitudinal section through a pressure medium-operated device.

Beschreibung des AusführungsbeispielsDescription of the embodiment
In der Figur ist mit 10 ein Gehäuse bezeichnet mit einer Längsbohrung 11, in welcher ein zylindrisches Teil 12 geführt ist, z. B. eine Kolbenstange. An der Längsbohrung 11 sind im Abstand voneinander zwei Ringnuten 13» 14 ausgebildet. In der Ringnut 16 ist ein Dichtring 15 zum Abdichten zwischen dem Teil 12 und der Längsbohrung angeordnet und in der Ringnut 13 ein Ölabstreifring 15· Am einen Ende des Gehäuses 10 befindet sich ein Druckraum 17» der beispielsweise durch einen nicht dargestellten Kolben begrenzt ist. Im Druckraum 17 herrscht Hochdruck, welcher sich über den Spalt zwischen der Längsbohrung 11 und dem Teil 12 bis zum Dichtring 16 fortpflanzt.In the figure, 10 designates a housing with a longitudinal bore 11 in which a cylindrical part 12 is guided, e.g. a piston rod. Two ring grooves 13» 14 are formed at a distance from one another on the longitudinal bore 11. A sealing ring 15 for sealing between the part 12 and the longitudinal bore is arranged in the ring groove 16 and an oil scraper ring 15 is arranged in the ring groove 13. At one end of the housing 10 there is a pressure chamber 17» which is delimited, for example, by a piston (not shown). In the pressure chamber 17 there is high pressure which propagates across the gap between the longitudinal bore 11 and the part 12 to the sealing ring 16.
Zwischen den Ringnuten 13» 14 befindet sich an der Längsbohrung noch eine Ringnut 19, in welche eine vom Äußeren des Gehäuses ausgehende Querbohrung 20 eindringt. In dieser ist ein Flüssigkeitssensor 21 angeordnet, welcher an eine elektrische Signaleinrichtung 22 mit Schalter 23 angeschlossen ist. Beim Sensor 21 handelt es sich um einen handelsüblichen Flüssigkeitsdetektor, insbesondere einen optischen.Between the ring grooves 13» 14, there is another ring groove 19 on the longitudinal bore, into which a transverse bore 20 extends from the outside of the housing. A liquid sensor 21 is arranged in this, which is connected to an electrical signaling device 22 with a switch 23. The sensor 21 is a commercially available liquid detector, in particular an optical one.
Wenn die Wirkung des Dichtrings 16 nicht mehr ausreichend ist und Flüssigkeit in die Ringnut 19 eindringt und damit den Sensor 21 benetzt, gibt dieser ein elektrisches Signal, welches den Schalter 23 schließt, worauf ein Warnsignal abgegeben wird. Die Undichtigkeit kann nun schnell durch Auswechseln des Dichtrings 16 behoben werden. Auf diese Weise erhält man eine sehr einfache Warneinrichtung für durchleckendes Drucköl, wodurch Schäden in der Einrichtung vermieden werden können.If the effect of the sealing ring 16 is no longer sufficient and liquid penetrates into the ring groove 19 and thus wets the sensor 21, the sensor emits an electrical signal which closes the switch 23, whereupon a warning signal is emitted. The leak can now be quickly remedied by replacing the sealing ring 16. In this way, a very simple warning device for leaking pressure oil is obtained, which can prevent damage to the device.
