Description

Schmiereinrichtung für Brennkraftmaschinen Die Erfindung betrifft eine Schmiereinrichtung für Brennkraftmaschinen, bei denen das gesamte im überschuß zugeführte Schmieröl vor der überführung zu den Schmierstellen gereinigt und gekühlt wird.Lubricating device for internal combustion engines The invention relates to a lubrication device for internal combustion engines, in which the whole in excess The lubricating oil supplied is cleaned and cooled before it is transferred to the lubrication points will.

Bei bekannten Einrichtungen dieser Art ist es üblich, das gesamte in die Schmierölleitung geförderte öl einem Sammelb--hälter, z. B. dem ülsumpf der Brennkraftmaschine, wieder zuzuleiten. Von da aus tritt es seinen Kreislauf von neuem an, der durch ölpumpe, Filter, ölkühler und Schrnierölleitung zum ölsumpf führt. Diese Einrichtungen haben den Nachteil, daß das überschüssige öl mit dem im ölbehälter vorhandenen unsauberen öl vermischt und durcli die Brennkraftmaschine erwärmt wird und daher von neuem gefiltert und gekühlt werden muß.In known devices of this type, it is customary to collect all of the oil conveyed into the lubricating oil line in a collecting container, e.g. B. the oil sump of the internal combustion engine to be fed back. From there it starts its cycle again, which leads through the oil pump, filter, oil cooler and tube oil line to the oil sump. These devices have the disadvantage that the excess oil is mixed with the unclean oil present in the oil container and is heated by the internal combustion engine and therefore has to be filtered and cooled again.

Die Erfindung bezweckt, diese Nachteile zu beseitigen. Sie besteht darin, daß der Schmierölüberschuß mittels einer hinter der letzten Schmierstelle an die Schmierleitung angeschlossenen besonderen Leitung unmittelbar zur ölp-umpe zurückgeleitet wird.The invention aims to eliminate these disadvantages. she consists in that the excess lubricating oil by means of a behind the last lubrication point special line connected to the lubrication line directly to the oil pump is returned.

In den Abbildungen ist eine Ausführungsform der Erfindung beispielsweise dargestellt. Abb. i zeigt die Längsansicht einer Brennkraftmaschine; Abb. -- ist eine Ansicht in Richtung 11 der Abb. i.In the figures, an embodiment of the invention is shown as an example. Fig. I shows the longitudinal view of an internal combustion engine; Fig - is a view in the direction 11 of Fig. I.

ZD Die Brennkraftmaschine i ist mit #e-in#er Schmierölpumpe 2, einem Schmierölfilter 3 und einem Schmierölkühler 4 ausgerüstet. In dem ÖlsumPf 5 der Brennkraftmaschine i liegt ein Ansaugerohr 6, welches mit dem Saugstuzen 7 der Schmierölpumpe 2 verbunden ist. 8 ist eine VerbindungslLeitung zwischen der Pumpe -- und dem Filter 3. 9 ist eine Verbindungsleitung zwi.schen dem Filter 3 -und dem Kühl#er 4. Vom Kühler 4 führt eine Leitung i o zu den Schmierstellen i i, z. B. d,-n Kurbel- und Pleuellagern der Brennkraftmaschine i. Am Ende der Leitung io hinter der letzten Schmierstelle ist ein üb2rseömventil 12 angeordnet, an welches sich eine Leitung 13 anschließt, die zur Schmierölpumpe 2 führt.ZD The internal combustion engine i is equipped with a lubricating oil pump 2, a lubricating oil filter 3 and a lubricating oil cooler 4. In the oil sump 5 of the internal combustion engine i there is an intake pipe 6 which is connected to the suction nozzle 7 of the lubricating oil pump 2. 8 is a VerbindungslLeitung between the pump - and the filter 3. Figure 9 is a connecting line zwi.schen the filter 3 -and the cooling he # 4. From the cooler 4 io a line leads to the lubrication points ii, z. B. d, -n crank and connecting rod bearings of the internal combustion engine i. At the end of the line io behind the last lubrication point, an overflow valve 12 is arranged, to which a line 13 connects, which leads to the lubricating oil pump 2.

Die Schmierung der Brennkraftmaschine, erfolgt in folgender Weise: Das Schmieröl fließt vom Sammelbehälter 5 über Schnü2#r,51-pumpe 2, Filter 3, ölkühler 4 und Leitung i o zu den einzelnen Schmierstellen i i d--r Maschine i. Nachdem es die Lager geschmiert hat, tritt es an den Seiten der Lager aus und sammelt sich in dem ÖlsumPf 5 der Kurbelwarme der Brennkraftmaschin-e i. Außer zur Schmierung ist das öl auch zur Kühlung notwendig. Aus diesem Grunde führt man be- sonders den Kurbelwellen- und. Pleuellagern einen überschuß an Schmieröl zu, der dazu dient, die durch die Lagerreibung entstanden,-Wärine abzuführen. Das ganze Schmiersysteni hat einen gewissen Widerstand, den die Öl-Pumpe 2 überwinden muß. Damit dieselbe, diesen Widerstand mit Sicherheit überwindet, fördert sie das Öl mit einem höher-en Druck in die Schmierölleitung, alseseigentlicU nötig wäre. Aus diesem Grunde ist am Ende der Schmierleitung io hinter der' letzten Schmierstelle ein überströniventil 12 eingeschaltet, welches auf den Druck, der etwa dem Widerstand entspricht, eingestellt ist. Ein Teil des gef#brd,erten Schmieröls strömt an der Stelle 12 dauernd über. Erfindungsgem.aß wird das überströniende 01 mittels einer besonderen Leitung 13 der Saugseite der Schmierölpumpe2 unmittelbar zugeführt. Die Leitung 13 verläuft bei dem Ausführungsheispiel außerhalb des Maschinengeliäuses.The internal combustion engine is lubricated in the following way: The lubricating oil flows from the collecting container 5 via Schnü2 # r, 51-pump 2, filter 3, oil cooler 4 and line io to the individual lubrication points ii d - r machine i. After it has lubricated the bearings, it emerges on the sides of the bearings and collects in the oil sump 5 of the crank heat of the internal combustion engine. In addition to lubrication, the oil is also required for cooling. For this reason, leading loading Sonders the crankshaft and. Conrod bearings to an excess of lubricating oil, which serves to dissipate the resulting from the bearing friction, -Wärine. The whole lubrication system has a certain resistance which the oil pump 2 has to overcome. In order for the same to surely overcome this resistance , it pumps the oil into the lubricating oil line at a higher pressure than would actually be necessary. For this reason, at the end of the lubrication line io behind the 'last lubrication point, an overflow valve 12 is switched on, which is set to the pressure which corresponds approximately to the resistance. Part of the contaminated lubricating oil overflows continuously at point 12. According to the invention, the overflowing 01 is fed directly to the suction side of the lubricating oil pump 2 by means of a special line 13. The line 13 runs in the exemplary embodiment outside of the machine gel.

Der Vorteil der Erfindung ergibt sich daraus, daß das schon gefilterteund gekühlte öl sofort in die PUMpe2 geleitet wird. Die Pumpe braucht nun nicht mehr soviel Öl wie sonst aus dem SammelbeUälter anzusaugen. Das übergeströmte, gefilterte und gekühlte 01 vermischt sich also mit einer viel geringeren Menge ungefilterten. und erwärmten Öls, so daß es schon am Anfang mit geringerer Temperatur und in weniger verschmutztem Zustand den Ölkreislauf beginnt.The advantage of the invention results from the fact that the oil that has already been filtered and cooled is immediately fed into the PUMP2. The pump no longer needs to suck in as much oil as usual from the collecting tank. The over flowed, filtered and cooled 01 So mixed with a much smaller amount of unfiltered. and heated oil, so that it starts the oil cycle at the beginning with a lower temperature and in a less polluted state.
