Fig. 1 zeigt die Lage des Pumpengehäuses 4 der Ölpumpe 3 in der vorderen Stirnseite des Zylinderkurbelgehäuses 1. Fig. 1 shows the location of the pump housing 4 of the oil pump 3 in the front end side of the cylinder crankcase 1.

Das Ölpumpengehäuse 4 liegt im Bereich der Schürze 6 un­ terhalb der Kurbelwellenmittenebene 16. Zusammen mit dem Ölpumpengehäuse 4 ist ein Ölpumpendruckraum 7 und ein Öl­ pumpensaugraum 8 in dem Zylinderkurbelgehäuse 1 einge­ gossen. Der Ölpumpendruckraum 7 steht in Strömungsverbin­ dung mit einer Ölverteilleitung 17, durch die das Schmier­ öl zu den Schmierstellen bzw. das Kühlöl zu den Kühlräumen geleitet wird.The oil pump housing 4 is in the apron 6 un below the crankshaft center plane 16th Together with the oil pump housing 4 , an oil pump pressure chamber 7 and an oil pump suction chamber 8 are poured into the cylinder crankcase 1 . The oil pump pressure chamber 7 is in flow connection with an oil distribution line 17 through which the lubricating oil is passed to the lubrication points and the cooling oil to the cooling rooms.

Der Ölpumpensaugraum 8 steht in Strömungsverbindung mit einem Ölansaugrohr 18, das in den Ölsumpf der Ölwanne 19 ragt.The oil pump suction chamber 8 is in flow connection with an oil suction pipe 18 which projects into the oil sump of the oil pan 19 .

Aus Fig. 2 gehen Anordnung und Antrieb der Ölpumpe 3 her­ vor. Das Pumpengehäuse 4 mit dem Ölpumpensaugraum 8 und dem Ölpumpendruckraum 7 ist integraler Bestandteil des Zy­ linderkurbelgehäuses 1. Das Pumpengehäuse 4 wird durch einen Ölpumpendeckel 9 abgeschlossen. Der Ölpumpendeckel 9 benötigt keine Öldichtung, da Lecköl über einen spritzöl­ dichten Raum 11 zurück in die Ölwanne 19 fließt.The arrangement and drive of the oil pump 3 proceed from FIG . The pump housing 4 with the oil pump suction chamber 8 and the oil pump pressure chamber 7 is an integral part of the cylinder crankcase 1 The pump housing 4 is closed by an oil pump cover 9 . The oil pump cover 9 does not require an oil seal, since leakage oil flows back into the oil pan 19 via a splash-proof space 11 .

Der Ölpumpendeckel 9 trägt ein Lager 10, in dem eine Pum­ penrotorwelle 12 gelagert ist. Das aus dem Lager 10 aus­ tretende Öl fließt ebenfalls durch den spritzöldichten Raum 11 in die Ölwanne 19 zurück. The oil pump cover 9 carries a bearing 10 in which a pump rotor shaft 12 is mounted. The oil emerging from the bearing 10 also flows back through the oil-tight space 11 into the oil pan 19 .

Mit der Pumpenrotorwelle 12 ist der Pumpenrotor 5 drehfest verbunden. Auf dem freien Ende der Pumpenrotorwelle 12 ist ein Zahnriemenrad 15 befestigt. Dieses ist nebst dem Zahn­ riemen 2 von einer Schutzhaube 21 abgedeckt, unter der sich ein ölfreier Raum 13 befindet.The pump rotor 5 is connected in a rotationally fixed manner to the pump rotor shaft 12 . A toothed belt wheel 15 is attached to the free end of the pump rotor shaft 12 . This is in addition to the toothed belt 2 covered by a protective hood 21 , under which an oil-free space 13 is located.

Der Durchtritt der Pumpenrotorwelle 12 vom spritzöldichten Raum 11 in den ölfreien Raum 13 ist durch eine Wellendich­ tung 14 abgedichtet.The passage of the pump rotor shaft 12 from the oil-tight space 11 in the oil-free space 13 is sealed by a shaft seal 14 .

Die Schmierölpumpe 3 funktioniert folgendermaßen:The lubricating oil pump 3 works as follows:

Das Schmieröl wird aus der Ölwanne 19 über das Ölansaug­ rohr 18 und den Ölpumpensaugraum 8 angesaugt und durch den Rotor 5 in den Ölpumpendruckraum 7 und die Ölverteillei­ tung 17 gefördert. Als Antrieb der Schmierölpumpe 3 dient der Zahnriemen 2, der auch zum Antrieb der Nockenwelle und der Einspritzpumpe Verwendung findet. Die spritzöldichte Abdeckhaube 20 macht eine öldichte Ausführung des Pumpen­ gehäuses 4 und des Ölpumpendeckels 9 überflüssig. Die Wellendichtung 14, die lediglich spritzöldicht sein muß, verhindert den Ölaustritt in den ölfreien Raum 13, so daß dort der Zahnriementrieb als Antrieb der Schmierölpumpe 3 verwendet werden kann. Durch das im Kurbelgehäuse 1 inte­ grierte Pumpengehäuse 4 entfällt ein separates Pumpenge­ häuse und die zwischen diesem und dem Kurbelgehäuse not­ wendigen Dichungen. Auf diese Weise wird eine kosten­ günstige und leckölsichere Schmierölpumpenanordnung ge­ schaffen.The lubricating oil is sucked from the oil pan 19 through the oil intake pipe 18 and the oil pump suction chamber 8 and through the rotor 5 into the oil pump pressure chamber 7 and the Ölverteillei device 17 . To drive the lubricating oil pump 3 is the toothed belt 2 , which is also used to drive the camshaft and the injection pump. The spray oil-tight cover 20 makes an oil-tight design of the pump housing 4 and the oil pump cover 9 superfluous. The shaft seal 14 , which only has to be splash-oil-tight, prevents the oil from escaping into the oil-free space 13 , so that the toothed belt drive can be used there to drive the lubricating oil pump 3 . Due to the integrated in the crankcase 1 pump housing 4, there is no need for a separate pump housing and the seals necessary between this and the crankcase. In this way, a cost-effective and leak-proof lubricating oil pump arrangement will create ge.
