w Anordnung des Saugtrichters der Schmierölpumpe in der ölwanne einer Brennkraftmaschine " w Arrangement of the suction funnel of the lubricating oil pump in the oil pan of an internal combustion engine "

Die Erfindung bezieht sich auf die Anordnung des Saugtrichtere der Schmierölpumpe in der Ölwanne einer Brennkraftmaschine.The invention relates to the arrangement of the suction funnel of the lubricating oil pump in the oil pan of an internal combustion engine.

Zwischen dem Saugtrichter und dem Boden der Ölwanne muß ein Mindestabstand vorliegen, damit genügend Querschnitt vorhanden ist, um beim Ansaugen des Schmieröles, insbesondere bei kaltem öl, den Ansaugwiderstand klein zu halten. Aus Pertigungsgründen muß aber eine Toleranz zugestanden werden, so daß dieser Abstand doppelt so groß wie der Mindestabstand werden kann. Das hat den Nachteil, daß bei abnehmende» Ölstand, insbesondere bei Kurvenfahrt oder beim Befahren von Steigungen und Gefällen oder auch beim Bremsen und scharfen Beschleunigen, der Saugtrichter aus dem ölspiegel herausragt. In diesem Pail wifd Luft angesaugt und eine Gefährdung der Lager tritt ein.There must be a minimum clearance between the suction funnel and the bottom of the oil pan are present so that there is enough cross-section to absorb the lubricating oil, especially when the oil is cold, the To keep suction resistance small. But for reasons of production a tolerance can be allowed so that this distance can be twice as large as the minimum distance. That has the disadvantage that with decreasing »oil level, especially when cornering or when driving up and down gradients or when braking and accelerating sharply, the suction funnel out of the oil level protrudes. In this pail air is sucked in and a hazard the camp enters.

Die der PJrfindung zugrunde liegende Aufgabe besteht darin, das Ansaugen von Luft unter den genannten Umständen zu vermeiden.The task on which the PJinvention is based is the suction of air under the circumstances mentioned.

Diese Aufgabe ist gemäß der Erfindung dadurch gelöst, daß der Saugtrichter mittels eines elastischen Abstandsstückes am Boden der Ölwanne abgestützt ist und die Saugöffnung des Saugtrichters in den Innenraum des hohlen Abstandsstückes mündet, und daß das Abstandsstück an seinem unteren Ende mit einer oder mehreren für luftfreies Absaugen niveaubestimmenden Öffnungen versehen ist.This object is achieved according to the invention in that the suction funnel by means of an elastic spacer on the floor the oil pan is supported and the suction opening of the suction funnel opens into the interior of the hollow spacer, and that the spacer at its lower end with one or more for air-free suction is provided with level-determining openings.

Die Öffnungen am unteren Ende des Abatandsstückes bilden genau definierbare Querschnitte zum Ansaugen des Schmieröles. Durch dieThe openings at the lower end of the Abatandsstückes form exactly definable cross-sections for sucking in the lubricating oil. Through the

Elastizität des Abstandsstückes werden toleranzbedingte Höhenunterschiede ausgeglichen. Dadurch wird erreicht, daß in jedem Motor stets der gleiche mindestnotwendige Querschnitt zur Schmierölansaugung zur Verfügung steht und außerdem der ölstand im Grenzfall bis auf einen Minimalen Wert heruntergefahren werden kann, ohne den Motor zu gefährden.The elasticity of the spacer is tolerance-related height differences balanced. This ensures that the same minimum cross-section for the suction of lubricating oil is always used in each engine is available and also the oil level in borderline cases can be reduced to a minimum value without endangering the motor.

Einzelheiten und weitere Merkmale der erfindungsgemäßen Anordnung sind im folgenden anhand eines in der Zeichnung dargestellten Anordnungsbeispieles beschrieben. In der Zeichnung bedeutenDetails and further features of the arrangement according to the invention are in the following with reference to an arrangement example shown in the drawing described. In the drawing mean

Pig. 1 einen vertikalen Schnitt durch die Anordnung Saugtrichter-Ölwanne, wobei nur die eine Hälfte des Saugtrichters und des Abstandsstückes gezeigt ist, undPig. 1 shows a vertical section through the suction funnel-oil pan arrangement, with only one half the suction cup and spacer is shown, and

Fig. 2 das Abstandsstück im Schnitt als Einzelteil der Anordnung in Fig. 1.Fig. 2 shows the spacer in section as an individual part of the Arrangement in Fig. 1.

Der Saugtrichter 10 ist in nicht gezeigter Weis® im wesentlichen ortsfest in der ölwanne gehaltert und mittels eines elastischen hülsenförmigen Abstandsstückes 11 am Boden 12 der Ölwanne abgestützt. Am unteren Hand 13 des Saugtrichters 10 is„t in einer inneren Nut 14 eine Blechringscheibe 15 zusammen, mit einem Siebfilter 16 flüssigkeitsdicht befestigt. Der innere Rand 17 der Blechscheibe 15 greift dichtend in eine Umfangsnut 18 am oberen wulstartigen Ringrand 19 des Abatandsstückes 11 ein. Das untere Ende 20 des Abstandsstückes 11 wird von einem relativ unelastischen Wulstrand 21 gebildet, deasen Stirnfläche 22 auf dem Boden 12 aufliegt. Der Wulstrand 21 ist mit Einbuchtungen 23 versehen, die Öffnungen 24 für den Durchtritt des Schmiermittels bilden. Zwischen dem oberen Rand 19 und dem unteren Wulstrand 21 ist ein kegelförmiges, relativ leicht elastisch verformbares Zwischenstück 25 vorgesehen, um die Einbautoleranzen zwischen dem unterenThe suction funnel 10 is essentially in a manner not shown held stationary in the oil pan and supported by means of an elastic sleeve-shaped spacer 11 on the bottom 12 of the oil pan. The lower hand 13 of the suction funnel 10 is in one inner groove 14 a sheet metal ring disk 15 together, with a sieve filter 16 fastened in a liquid-tight manner. The inner edge 17 of the sheet metal disc 15 engages in a sealing manner in a circumferential groove 18 at the top bead-like ring edge 19 of the Abatandsstückes 11 a. The lower The end 20 of the spacer 11 is formed by a relatively inelastic beaded rim 21, which deases the end face 22 on the ground 12 rests. The bead 21 is provided with indentations 23, form the openings 24 for the passage of the lubricant. Between the upper edge 19 and the lower bead 21 is a conical, relatively easily elastically deformable intermediate piece 25 is provided to reduce the installation tolerances between the lower

Die Höhe 26 der Einbuchtungen 23 bestimmt den tiefsten Ölstand in der ölwanne, bei dem noch luftfrei abgesaugt werdenEqualize the edge 13 of the suction funnel 10 and the bottom 12 of the oil pan. The height 26 of the indentations 23 determines the deepest Oil level in the oil sump at which air-free suction is still possible

In den Innenraum 27 zwischen den Teilen 10 und 16 mündet in nicht gezeigter Weise die Saugleitung der Schmierölpumpe.In the interior 27 between the parts 10 and 16 does not open into As shown, the suction line of the lubricating oil pump.

Wie aus der Pig. 1 ohne weiteres ersichtlich ist, kann sich der Abstand 28 des Saugtrichters 10 vom Boden 12 in bestimmten, im wesentlichen durch die Längenverformbarkeit des Zwischenstückes 25 gegebenen Grenzen ändern, ohne daß die für luftfreies Absaugen niveaubestimmende Höhe 26 beeinflußt wird.Like from the Pig. 1 is readily apparent, the Distance 28 of the suction funnel 10 from the bottom 12 in certain, essentially by the deformability of the length of the intermediate piece 25 change given limits without influencing the height 26, which determines the level for air-free suction.
