Abstract

Oil tank for I.C. engine comprises two simultaneously operating suction pumps, one of which has a much greater output. The suction pipe of the second pump is in the form of a channel which extends into the oil tank and of which the suction opening (15) points in a direction opposite to the direction (16) of suction produced by the first pump. For example, the first pump conveys oil to the engine, and the second pump conveys oil to auxiliary apparatus using oil for cooling. The output of the first pump per min. is equal to a multiple of the content of the oil tank (11) and a multiple of the output of the second pump.

Description

(Jlbehälter Die Erfindung bezieht sich auf einen blbehälter einer Brennkraftmaschine, aus dem zwei Pumpen gleichzeitig 51 ansaugen und die erste Pumpe gegenüber der zweiten eine vielfach größere Förderleistung besitzt. (Oil container The invention relates to a container of a Internal combustion engine from which two pumps suck in 51 and the first pump compared to the second has a much larger delivery rate.

Die erste Pumpe fördert Schmieröl für die Brennkraftmaschine aus dem blbehälter, während die zweite Pumpe ein an der Brennkraftmaschine angebautes Hilfsaggregat mit 1 zur Kühlung versorgt.The first pump conveys lubricating oil for the internal combustion engine from the bl container, while the second pump is an auxiliary unit attached to the internal combustion engine supplied with 1 for cooling.

Im vorliegenden Fall besteht die Gefahr einer verminderten Fördermenge der zweiten Pumpe mit teilweisem Totalausfall bei voller Förderleistung der ersten Pumpe.In the present case, there is a risk of a reduced delivery rate of the second pump with partial total failure at full delivery rate of the first Pump.

Diese Aussetzer der zweiten Pumpe bedeuten eine Betriebsgefährdung für das Hilfsaggregat.These failures of the second pump represent an operational hazard for the auxiliary unit.

Es ist deshalb Aufgabe der Erfindung, den ölbehälter so zu gestalten, daß beide Pumpen ohne gegenseitige Behinderung ihre projektierte Förderleistung erbringen können.It is therefore the object of the invention to design the oil container so that both pumps reach their projected delivery rate without any mutual hindrance can provide.

Diese Aufgabe löst die Erfindung durch eine Saugleitung der zweiten Pumpe in Form eines in den ölbehälter hineinragenden Kanals, dessen Saugöffnung der von der ersten Pumpe im ölbehälter verursachten Ansaugströmung entgegengerichtet ist. Mit dieser Anordnung wird der Staudruck der Ansaugströmung der ersten Pumpe zum Aufbau eines Druckes im Saugkanal der zweiten Pumpe ausgenutzt.This object is achieved by the invention by a suction line of the second Pump in the form of a channel protruding into the oil container, its suction opening counteracts the suction flow caused by the first pump in the oil tank is. With this arrangement, the back pressure the intake flow the first pump is used to build up pressure in the suction channel of the second pump.

Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, daß sich eine stetige und gesteigerte Förderleistung der zweiten Pumpe ergibt und daß die Betriebsgefährdung für das mit Kühlöl versorgte Hilfsaggregat beseitigt ist.The advantages achieved with the invention are, in particular, that there is a steady and increased delivery rate of the second pump and that the operational hazard for the auxiliary unit supplied with cooling oil is eliminated is.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen Fig. 1 eine Draufsicht auf einen dlbehälter, Fig. 2 einen Querschnitt des Olbehälters nach der Linie II-II in Fig. 1.An embodiment is shown in the drawing and will described in more detail below. 1 shows a plan view of an oil container, FIG. 2 shows a cross section of the oil container along the line II-II in FIG. 1.

In einem ölbehälter ii einer nicht dargestellten Brennkraftmaschine, aus dem zwei Pumpen gleichzeitig dl ansaugen, sind zwei Saugleitungen 12, 13 angeordnet. Über die Saugleitung 12 fördert die erste Pumpe Schmieröl für die Brennkraftmaschine. Die zweite Pumpe versorgt über die Saugleitung 13 ein an die Brennkraftmaschine angebautes Hilfsaggregat mit dl zur Kühlung.In an oil container ii of an internal combustion engine, not shown, Two suction lines 12, 13 are arranged from which two pumps suck in dl at the same time. The first pump conveys lubricating oil for the internal combustion engine via the suction line 12. The second pump supplies a to the internal combustion engine via the suction line 13 attached auxiliary unit with dl for cooling.

Die Förderleistung der ersten Pumpe pro Minute entspricht dem mehrfachen Inhalt des olbehälters, und sie ist außerdem vielfach größer als die Förderleistung der zweiten Pumpe. Daraus resultiert eine ausgeprägte Ansaugströmung (Pfeile 16) im O3lbehälter 11 in Richtung auf den Saugmund 14 der Saugleitung 12, Um den Staudruck dieser Ansaugströmung für die Sauglei tung 13 der zweiten Pumpe auszunutzen, ist die Saugleitung 13 in Form eines in den ölbehälter hineinragenden Kanals verlängert, dessen Saugöffnung 15 der von der ersten Pumpe verursachten Ansaugströmung entgegengerichtet ist.The delivery rate of the first pump per minute corresponds to several times this Contents of the oil container, and it is also many times greater than the delivery rate the second pump. This results in a pronounced intake flow (arrows 16) in the O3l container 11 in the direction of the suction mouth 14 of the suction line 12, Around to utilize the back pressure of this suction flow for the suction line 13 of the second pump, the suction line 13 is extended in the form of a channel protruding into the oil container, its suction opening 15 is directed in the opposite direction to the suction flow caused by the first pump is.

Die Wirksamkeit der Anordnung ist nicht an die im Beispiel dargestellte Gußausführung gebunden, sondern sie läßt sich auch in anderer Form, z.B. durch entsprechend ausgebildete Rohrleitungen, verwirklichen.The effectiveness of the arrangement does not match that shown in the example Cast version bound, but it can also be in another form, e.g. by corresponding trained pipelines.
