Die Aufgabe der Erfindung besteht demgegenüber darin, eine einfache und raumsparende Einrichtung zur Förderung des Schmiermittels für ein Trockensumpfschmiersystem einer Brennkraftmaschine zu schaffen, die sich außerdem durch sehr billige Herstellungskosten auszeichnet.The object of the invention is to provide a simple and space-saving device for conveying the lubricant for a dry sump lubrication system to create an internal combustion engine, which is also characterized by very cheap manufacturing costs excels.

'Diese Aufgabe wird erfindungsgemäß dadurch gelöst, das .das SchmiermIttel in bekannter Weise mittels einer angetriebenen Druckpumpe durch eine Druckleitung zu den Schmierstellen der Brennkraftmaschine und mittels einer antriebslosen Saugpumpe aus dem Trockensumpf in den Schmiermittelvorratsbehälter gefördert wird. Vorteilhaft ist hierbei, daß die Saugpumpe durch eine mit der Druckleitung verbundene Düse gebildet wird, deren Düsenöffnung in den Schmiermittelvorratsbehälter mündet und von dem kleinsten Durchmesser eines sich vor und hinter der Düsenöffnung erweiternden Diffusors umgeben ist, der mit einer in den Trockensumpf der Brennkraftmaschine mündenden Saugleitung verbunden ist. Zweckmäßig ist, daß die Saugleitung hinter der Düsenöffnung in den durch den Diffusor gebildeten Raum mündet.According to the invention, this object is achieved in that the lubricant in a known manner by means of a driven pressure pump through a pressure line to the lubrication points of the Internal combustion engine and by means of a driveless Suction pump is conveyed from the dry sump into the lubricant reservoir. The advantage here is that the suction pump is connected to the pressure line by a Nozzle is formed, the nozzle opening opens into the lubricant reservoir and from the smallest diameter one that widens in front of and behind the nozzle opening Diffuser is surrounded with a in the dry sump of the internal combustion engine opening suction line is connected. It is useful that the suction line is behind the nozzle opening opens into the space formed by the diffuser.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß diese Schmiermittelfördereinrichtung für eine Brennkraftmaschine mit Trockensumpfschmierung nur eine angetriebene Pumpe benötigt und die Rückförderung des Schmiermittels aus dem Trockensumpf in den Schmiermittelvorratsbehälter durch eine antriebslose Strahlpumpe erfolgt, wodurch mit einfachen Mitteln eine billige und sicher funktionierende Einrichtung zur Förderung des Schmiermittels von Brennkraftmaschinen mit Trockensumpfschmierung erhalten wird.The advantages achieved with the invention are in particular: that this lubricant delivery device for an internal combustion engine with dry sump lubrication only a driven pump is required and the return of the lubricant the dry sump into the lubricant reservoir by a non-powered jet pump takes place, whereby a cheap and safe functioning facility with simple means for conveying the lubricant of internal combustion engines with dry sump lubrication is obtained.

In der Zeichnung ist eine beispielsweise Ausführungsform der Schmiermittelfördereinrichtung für eine Brennkraftmaschine gemäß der Erfindung anhand eines Querschnittes durch ein Kurbelgehäuse einer Brennkraftmaschine im Bereich der Druckpumpe gezeigt.In the drawing is an example embodiment of the lubricant delivery device for an internal combustion engine according to the invention based on a cross section through a crankcase of an internal combustion engine shown in the area of the pressure pump.

In einem Kurbelgehäuse 1 einer Brennkraftmaschine 2 ist eine Druckpumpe 3 angeordnet, die von einem Zahnrad 4 einer Nokkenwelle angetrieben wird. Die Druckpumpe 3 ist über eine Leitung 5 mit einem Schmiermittelvorratsbehälter 6 verbunden, der in dem Kurbelgehäuse 1 durch eine Wandung 7 getrennt von dem Trockensumpf 8 der Brennkraftmaschine 2 angeordnet ist.A pressure pump is located in a crankcase 1 of an internal combustion engine 2 3 arranged, which is driven by a gear 4 of a camshaft. The pressure pump 3 is connected via a line 5 to a lubricant reservoir 6, the in the crankcase 1 separated from the dry sump 8 by a wall 7 Internal combustion engine 2 is arranged.

Eine Druckleitung 9 t von der Druckpumpe 3 zu den nicht näher dargestellten Lagerstellen der Brennkraftmaschine 2.A pressure line 9 t from the pressure pump 3 to the not shown Bearing points of the internal combustion engine 2.

Eine mit der Druckleitung 9 verbundene Düse 10 ist in der Wandung 7 gehalten und erstreckt sich mit ihrer Düsenöffnung 11 in den Schmiermittelvorratsbehälter 6. Die Wandung 7 besitzt im Bereich der Düse 10 eine kugelförmige Ausnehmung 12, die durch einen Diffusor 13 so verschlossen wird, daß der kleinste Durchmesser des Diffusors 13 in der Ebene der Düsenöffnung 11 angeordnet ist. Der Diffusor 15 ist aus einer Leichtmetallegierung hergestellt und wird mittels Schrauben 14 an der Wandung 7 befestigt. Die kugelförmige Ausnehmung 12 ist über eine Saugleitung 15 mit dem Trockensumpf 8 der Brennkraftmaschine 2 verbunden, aus dem über die Saugleitung 15 mittesl einer durch die Teile 10 bis 14 gebildeten Saugpumpe 16 das Schmiermittel in den Schmiermittelvorratsbehälter gefördert wird.A nozzle 10 connected to the pressure line 9 is in the Wall 7 held and extends with its nozzle opening 11 in the lubricant reservoir 6. The wall 7 has a spherical recess 12 in the region of the nozzle 10, which is closed by a diffuser 13 so that the smallest diameter of the Diffuser 13 is arranged in the plane of the nozzle opening 11. The diffuser 15 is made of a light metal alloy and is by means of screws 14 on the Wall 7 attached. The spherical recess 12 is via a suction line 15 connected to the dry sump 8 of the internal combustion engine 2, from which via the suction line 15 by means of a suction pump 16 formed by the parts 10 to 14, the lubricant is conveyed into the lubricant reservoir.

Die Wirkungsweise der Schmiermittelfördereinrichtung ist folgende: Bei laufender Brennkraftmaschine 2 wird durch das Nockenwellenzahnrad 4 die Druckpumpe 5 angetrieben, wodurch diese aus dem Schmiermittelvorratsbehälter 6 über die Leitung 5 Schmiermittel ansaugt und über die Druckleitung 9 unter Druck zu den Schmierstellen der Brennkraftmaschine 2 fördert.The mode of operation of the lubricant delivery device is as follows: When the internal combustion engine 2 is running, the camshaft gear 4 activates the pressure pump 5 driven, whereby this from the lubricant reservoir 6 via the line 5 Sucks in lubricant and via the pressure line 9 under pressure to the lubrication points the internal combustion engine 2 promotes.

Ein Teil des Schmiermittels wird durch die Düse 10 hindurch zurück in den Schmiermittelvorratsbehälter 6 gefördert. Die Fließgeschwindigkeit des in die Düse 10 eintretenden Schmiermittels wird durch die Düsenöffnung- 11 erhöht. Da die Düsenöffnung 11 im Bereich des kleinsten Durchmessers des Diffusors 15 angeordnet ist, wird die Fließgeschwindigkeit des Schmiermittels im Diffusor 15 bei gleichzeitigem Druckanstieg verringert. Hierdurch wird riun mittels der Saugleitung 15 Schmiermittel aus dem Trockensumpf 8 der Brennkraftmaschine 2 in die Ausnehmung 12 gesaugt und unter Vermischung mit dem aus der DUse 10 austretenden Schmiermittel in den Schmiermittelvorratsbehälter 6 gefördert.Some of the lubricant is returned through the nozzle 10 conveyed into the lubricant reservoir 6. The flow rate of the in The lubricant entering the nozzle 10 is increased through the nozzle opening 11. Since the nozzle opening 11 is arranged in the area of the smallest diameter of the diffuser 15 is, the flow rate of the lubricant in the diffuser 15 at the same time Reduced pressure increase. As a result, lubricant is supplied by means of the suction line 15 sucked from the dry sump 8 of the internal combustion engine 2 into the recess 12 and mixed with the lubricant emerging from the nozzle 10 in the lubricant reservoir 6 promoted.
