Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei diesem sogenannten pneumatisch - hydraulischen Kraftsafnmler soll die Absorption der den Gegendruck ausübenden Luft oder Gase durch die Druckflüssigkeit dadurch vermieden werden, dafs die Berührung des luft- oder gasförmigen Mediums mit der Druckflüssigkeit durch eine auf letztere aufgegossene Flüssigkeitsschicht verhindert wird, welche eine solche' Stärke oder Höhe hat und von solcher Beschaffenheit ist, dafs sie wie ein zwischen Medium und Druckflüssigkeit eingeschalteter Kolben wirkt und weder das Medium absorbirt, noch sich mit der Druckflüssigkeit mischt.With this so-called pneumatic-hydraulic force detector, the absorption the back pressure exerting air or gases avoided by the hydraulic fluid that the contact of the air or gaseous medium with the hydraulic fluid is prevented by a liquid layer poured onto the latter, which one has such strength or height, and is of such a quality that it is like an in-between Medium and hydraulic fluid switched on piston acts and neither the medium absorbs, nor mixes with the hydraulic fluid.

In der Zeichnung ist ein solcher Kraftsammler beispielsweise dargestellt. Derselbe hat die Form eines gewöhnlichen Windkessels. Die sonst üblichen festen Kolben oder Plunger bei Kraftsammlern sind fortgefallen. Statt deren ist auf die Druckflüssigkeit eine auf derselben schwimmende Flüssigkeitsschicht, z. B. eine Oelschicht aufgegossen. Alsdann wird in den Behälter A von oben ein luft- oder gasförmiges Medium eingeprefst, welches den nöthigen Gegendruck auf die Druckflüssigkeit unter Vermittelung der schwimmenden Trennungsschicht ausübt, ähnlich wie bei einem gewöhnlichen Kraftsammler das Belastungsgewicht auf das Wasser unter Vermittelung eines Plungers oder Kolbens drückt.Such a force collector is shown, for example, in the drawing. It has the shape of an ordinary air pocket. The usual fixed pistons or plungers in force collectors have been omitted. Instead, a liquid layer floating on the same, z. B. poured a layer of oil. Then an air or gaseous medium is pressed into the container A from above, which exerts the necessary counter pressure on the hydraulic fluid by means of the floating separating layer, similar to a common force collector, which presses the weight of the load on the water by means of a plunger or piston.

Die Höhe der schwimmenden und trennenden Flüssigkeitsschicht kann durch einen von ihr getragenen Schwimmer B vergröfsert werden, bezw. wird bei der Benutzung eines Schwimmers eine geringere Menge solcher Flüssigkeit ausreichen, um eine grofse und genügende Höhe der Trennungsschicht zu erhalten und derselben Undurchdringlichkeit bei Stöfsen zu verleihen.The height of the floating and separating liquid layer can be increased by a float B carried by it, respectively. If a float is used, a small amount of such liquid will suffice to maintain a great and sufficient height of the separating layer and to make it impervious to impact.

Der Schwimmer steht mit einem Absperrorgan C in Verbindung, durch welches beim Sinken des Standes der Druckflüssigkeit, bezw. beim Entleeren des Behälters A der Ausflufs E zur Druckleitung geschlossen wird, so dafs nichts von der trennenden Flüssigkeitsschicht in die Druckleitung abfliefsen kann.The float is connected to a shut-off element C through which, when the level of the pressure fluid drops, respectively. When the container A is emptied, the outflow E to the pressure line is closed so that nothing of the separating liquid layer can flow off into the pressure line.

Die communicirende Röhre G mit Schauglas F dient zur Beobachtung der im Behälter A stattfindenden Schwankungen der Flüssigkeitsstände. Zum Zweck der leichteren Erkennung derselben kann die trennende Flüssigkeitsschicht gefärbt sein.The communicating tube G with sight glass F is used to observe the fluctuations of the liquid level taking place in the container A. For the purpose of easier identification of the same, the separating liquid layer can be colored.

Wie leicht ersichtlich, ermöglicht diese Einrichtung, jeden Windkessel in- einen Kraftsammler ,umzuwandeln, wodurch einem bei Druckwasseranlagen längst gefühlten Bedürfnifs abgeholfen, sowie die Absorption der Prefsluft durch das Druckwasser bei noch so hohem Druck mit voller Sicherheit ausgeschlossen ist.As is easy to see, this device enables every air chamber to be turned into a force collector to convert, whereby a need that has long been felt in pressurized water systems remedied, as well as the absorption of the pre-air by the pressurized water, no matter how high it is Printing is excluded with complete certainty.
