Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung hat eine Verbesserung an den zur Bestimmung der Zähflüssigkeit von Oelen dienenden Vorrichtungen, den sogen. Viscosimetern, zum Gegenstande, welcher bezweckt, den hydrostatischen, auf die Ausflufsöffnung wirkenden Druck während der ganzen Messung constant zu erhalten. Eine derartige Vorrichtung ist in beiliegender Zeichnung in einem senkrechten, durch die Mitte gehenden Schnitte dargestellt.The present invention has an improvement on those for determining the viscosity of Oelen serving devices, the so-called. Viscometers, to the object which aims to keep the hydrostatic pressure acting on the outflow opening constant throughout the measurement. Such a one Device is in the accompanying drawing in a vertical, through the middle Sections shown.

Wie aus derselben ersichtlich, wird die Vorrichtung von einem Dreifufs getragen und besteht aus zwei über einander angeordneten, durch ein Fallrohr c mit einander verbundenen, doppelwandigen Gefäfsen α und b, von welchen das untere b in üblicher Weise mit dem Ausflufsstutzen d versehen ist, unterhalb dessen ein graduirtes. Gefäfs aufgestellt ist. Sowohl das Fallrohr c als auch der Ausflufsstutzen d sind mit je einem Ventil g bezw. h versehen, welches durch je einen an dem betreffenden Gefäfse angeordneten Hebel k bezw. / beeinflufst wird; die Hebel / k sind durch eine senkrechte, mit Druckknopf versehene Zugstange m verbunden, so dafs die beiden Ventile nur gleichzeitig geöffnet und geschlossen werden können. Die zwischen den Dpppelwandungen liegenden Ringräume der beiden Gefäfse α b, von welchen jener des unteren geschlossen ist, stehen durch mehrere Fallfohre η η mit einander in Verbindung; an tiefster Stelle des Ringraumes des Gefäfses b ist eine durch Hahn absperrbare Ausflufsbezw. Ausblasöffnung ρ angeordnet.As can be seen from the same, the device is carried by a tripod and consists of two double-walled vessels α and b arranged one above the other, connected by a downpipe c , of which the lower b is provided in the usual way with the outflow nozzle d below of which a graduate. The vessel is set up. Both the downpipe c and the outflow nozzle d are each with a valve g respectively. h provided, which respectively by one arranged on the respective vessel lever k . / is influenced; the levers / k are connected by a vertical pull rod m provided with a push button, so that the two valves can only be opened and closed at the same time. The annular spaces between the double walls of the two vessels α b, of which that of the lower one is closed, are connected to one another by several drop tubes η η; at the deepest point of the annular space of the vessel b is an outflow or valve that can be shut off by a valve. Arranged exhaust opening ρ .

Bei Ausführung von Messungen werden die beiden Ventile g h geschlossen und beide Gefäfse α b bis zu den an den Innenseiten derselben angebrachten Niveaumarken mit dem zu untersuchenden OeIe gefüllt. In den Ringraum des oberen Gefäfses α wird nunmehr so lange Wasser eingefüllt, bis dasselbe nach Ausfüllen des unteren Ringraumes bis zum OeI-niveau des oberen Gefäfses gestiegen ist.When measurements are carried out, the two valves gh are closed and both vessels α b are filled with the oil to be examined up to the level marks attached to the inside of the same. Water is now poured into the annular space of the upper vessel α until it has risen to the oil level of the upper vessel after the lower annular space has been filled.

Vor der Messung und während derselben wird das OeI durch die die beiden Gefäfse umgebenden Wassermäntel in bekannter Weise auf bestimmte Temperatur gebracht und erhalten, was durch die im unteren und oberen Gefäfse sowie dem äufseren Ringraume des oberen Gefäfses angeordneten Thermometer controlirt wird.Before and during the measurement, the oil is passed through the two vessels surrounding water jackets brought to a certain temperature in a known way and maintained, what through the thermometers arranged in the lower and upper vessels as well as in the outer annular space of the upper vessel is controlled.

Zur Ausführung der Messung wird nunmehr die Zugstange nt nach abwärts gedrückt, wodurch die beiden gleich calibrirten Oeffnungen c d freigegeben werden und das OeI nach Mafsgabe des Ausflusses aus dem unteren Gefäfse b aus dem oberen α nachfliefst, wodurch das Oelniveau im ersteren Gefäfse und somit auch der auf die Ausflufsöffnung d wirkende hydrostatische Druck während der ganzen Messung constant bleibt.To carry out the measurement, the pull rod nt is now pushed downwards, whereby the two equally calibrated openings cd are released and the oil flows from the upper α according to the amount of outflow from the lower vessel b , whereby the oil level in the first vessel and thus also the The hydrostatic pressure acting on the outflow opening d remains constant during the entire measurement.
