In der Technik sind ölzuführungsvorrichtungen im Gebrauch, bei welchen das öl in Tropfenform der Verbrauchsstelle zugeführt werden muß, wobei es auf eine genaue Innehaltung und Regelbarkeit der sekundlich oder minutlich zugeführten ölmenge ankommt, so z. B. bei Zementieröfen, bei welchen das Öl für den Glühprozeß zugeführt werden muß. Bei den bekannten Tropfölreglern können leichtIn the art, oil supply devices are in use, in which the oil in Droplet form must be supplied to the point of use, whereby there is an exact pause and controllability of the quantity of oil added every second or minute, so z. B. in cementing furnaces in which the oil must be supplied for the annealing process. With the known drip oil regulators you can easily

ίο Verstopfungen des Querschnittes des Reglers auftreten, welcher entsprechend den geringfügigen Mengen des tropfenweise einzuführenden Öles sehr klein ist. Damit findet dann eine Störung des gleichmäßigen Ölzuflusses statt, was von großem Schaden sein kann. Handelt es sich z. B. um einen Glühprozeß, so wird durch eine solche Störung der ölzuführung der ganze zum Härten eingebrachte Satz von Werkstücken verdorben.ίο blockages occur in the cross section of the regulator, which is very small due to the small amounts of oil to be introduced drop by drop. This then disrupts the even flow of oil, which can be very damaging. Is it z. B. an annealing process, the whole set of workpieces brought in for hardening is spoiled by such a disruption of the oil supply.

Gegenstand der vorliegenden Erfindung ist nun eine neue Feinregelung des ölzuflusses von solchen Tropfölern/ wobei vor demselben ein Luftventil, das an sich bekannt ist, geschaltet wird, dessen Querschnitt regelbar ist und damit die Menge des in Tropfenform austretenden Öles ohne Möglichkeit der Verstopfung des Querschnittes des Rohres, da durch diesen nur Luft hindurchtritt.The subject of the present invention is a new fine control of the oil inflow of such drip oilers / with an air valve, which is known per se, connected in front of the same whose cross-section is adjustable and thus the amount of oil escaping in the form of drops without the possibility of clogging the cross-section of the pipe, as only air passes through it.

Das Wesen der Erfindung besteht also darin,The essence of the invention consists in

daß vor dem eigentlichen öltropfer eine an sich bekannte Ölzuführungsvorrichtung geschaltet ist, die als luftdicht abgeschlossener ölbehälter ausgebildet und mit einer Luftleitung versehen ist, die durch ein Feinregelventil geschlossen wird, dermaßen, daß je nach der Einstellung des Feinregelventils der Unterdruck in dem luftdicht abgeschlossenen Behälter sich einstellt und demgemäß die abtropfende ölmenge nach der Differenz zwischen Unterdruck der Luft im Ölbehälter und Ölspiegelhöhe an der Abtropfstelle geregelt wird. In der Zeichnung ist die Erfindung beispielsweise in einer Ausführungsform in Fig. 1 im Schnitt dargestellt, während Fig. 2 das Feinregelventil im vergrößerten Maßstabe im Schnitt veranschaulicht. Es ist 1 der öltropfer, der durch Leitung 2 mit Absperrhahn 3 mit dem luftdicht abgeschlossenen vorgeschalteten ölbehälter 4 verbunden ist, der seinerseits mit Öl durch einen mit Bodenrohr 5 versehenen Trichter 6 aufgefüllt werden kann. Dieser luftdicht abgeschlossene ölbehälter 4 steht mit der Außenluft durch eine Leitung 7 in Verbindung, an deren freiem Ende das Feinregelventil 8 sich befindet mit dem vorgeschalteten Wattefilter 9.that in front of the actual oil dripper a known oil supply device is connected is designed as an airtight oil container and with an air line is provided, which is closed by a fine control valve, so that depending on the setting of the fine control valve Underpressure in the airtight container is set and accordingly the dripping Oil quantity according to the difference between the negative pressure in the air in the oil container and the oil level is regulated at the drip point. In the drawing the invention is for example shown in section in one embodiment in FIG. 1, while FIG. 2 shows the fine control valve illustrated on an enlarged scale in section. It is 1 the oil dropper that through line 2 with shut-off valve 3 with the airtight sealed upstream oil container 4 is connected, which in turn is provided with oil through a bottom pipe 5 Hopper 6 can be filled. This hermetically sealed oil container 4 stands with the outside air through a line 7 in connection, at the free end of the fine control valve 8 is located with the upstream cotton filter 9.
