Abstract
Description
Die Erfindung betrifft eine Baugruppe zur Ölrückführung an einer Brennkraftmaschine mit einer Ölrücklaufleitung, die mit einem Rohrstutzen in Wirkverbindung steht.The The invention relates to an assembly for oil return to an internal combustion engine with an oil return line, which is in operative connection with a pipe socket.
Für verschiedenartige technische Einsatzgebiete ist es notwendig, aus einem strömenden Medium gasförmige oder flüssige Bestandteile abzuscheiden. Eine typische Anwendung sind Brennkraftmaschinen, bei denen beispielsweise Blow-By-Gase aus dem Kurbelgehäuse oder Ölpartikel aus Luftführungen separiert werden müssen, um die Funktionsfähigkeit der jeweiligen Baugruppe zu gewährleisten.For different types technical applications, it is necessary from a flowing medium gaseous or liquid To separate components. A typical application is internal combustion engines, where, for example, blow-by gases from the crankcase or oil particles from air ducts have to be separated to the functionality to ensure the respective module.

Die Vorteile einer als Siphon wirksamen Baugruppe im Strömungsweg flüssiger Medien haben dazu geführt, dass eine Anwendung dieses Funktionsprinzips zunehmend für weitere technische Lösungen Beachtung findet. Dies betrifft beispielsweise den Ölrücklauf an einer Brennkraftmaschine, der bisher überwiegend realisiert wird, indem eine Ölrücklaufleitung von einem Ölabscheider direkt auf einen Rohrstutzen befestigt wird, der vorzugsweise im Zylinderkurbelgehäuse, in der Ventilhaube oder in der Ölwanne abgestützt ist. Sofern dieser Strömungsverbindung ein Siphon zugeordnet werden soll, erfolgt dies üblicherweise durch eine Neukonstruktion von Zylinderkurbelgehäuse, Ventilhaube oder Ölwanne. Dabei wird in diesen Baugruppen im Eintrittsbereich des mit der Ölrücklaufleitung verbundenen Rohrstutzens eine wannenförmige Ausnehmung ausgestaltet, welche die Funktion eines Siphonbeckens übernimmt. Der hierfür notwendige Konstruktions-, Herstellungs- und Kostenaufwand ist jedoch erheblich, so dass eine derartige Vorgehensweise lediglich bei der Konstruktion einer neuen Brennkraftmaschine mit einer großen zu erwartenden Produktionsstückzahl gerechtfertigt ist. Für eine Nachrüstung bereits verfügbarer Brennkraftmaschinen oder für relativ kleine Serienproduktionen ist dieser Aufwand jedoch nicht akzeptabel.The Advantages of an effective as a siphon assembly in the flow path liquid Media have led that one application of this principle of operation is increasingly for others technical solutions Attention is paid. This applies for example to the oil return an internal combustion engine, which has hitherto been predominantly realized, by an oil return line from an oil separator is attached directly to a pipe socket, preferably in Cylinder crankcase, in the valve cover or in the oil sump supported is. If this flow connection a siphon is to be assigned, this is usually done by a redesign of cylinder crankcase, Valve cover or oil pan. there is in these assemblies in the inlet area of the oil return line connected pipe socket designed a trough-shaped recess, which assumes the function of a siphon basin. The necessary for this However, design, manufacturing and cost is significant, so that such an approach only in the construction justified a new internal combustion engine with a large expected production number is. For a retrofit already available Internal combustion engines or for However, this effort is not relatively small series productions acceptable.
Aufgabe der Erfindung ist es, eine Baugruppe zur Ölrückführung an einer Brennkraftmaschine zu schaffen, die eine Siphonwirkung erzielt und die kostengünstig herstellbar und montierbar und die sowohl für eine Erstausstattung als auch für eine Nachrüstung von Brennkraftmaschinen geeignet ist.task The invention is an assembly for oil return to an internal combustion engine to create that achieves a siphon effect and the inexpensive to produce and mountable and for both an initial equipment as well as for a retrofit of internal combustion engines is suitable.
Diese Aufgabe wird gelöst, indem die Baugruppe aus drei baulich ineinander angeordneten Segmenten besteht, von denen das erste Segment eine rohrförmige Kontur, das zweite Segment eine becherförmige Kontur und das dritte Segment eine hülsenförmige Kontur aufweist, wobei das erste Segment mit dem einen endseitigen Abschnitt mit einer von Öl zu entsorgenden Baugruppe verbunden und mit dem anderen zum Rohrstutzen gerichteten endseitigen Abschnitt innerhalb vom freien Innenraum des zweiten Segmentes angeordnet ist und wobei die derart ineinander angeordneten Abschnitte gemeinsam vom dritten Segment überdeckt werden, das mit dem einen Endabschnitt an der Außenkontur des ersten Segmentes oberhalb der becherförmigen Kontur des zweiten Segmentes und mit dem anderen Endabschnitt an der Außenkontur des Rohrstutzens anliegt. Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche, deren Merkmale im Ausführungsbeispiel näher beschrieben werden.These Task is solved by the assembly of three structurally arranged segments of which the first segment has a tubular contour, the second segment a cup-shaped Contour and the third segment has a sleeve-shaped contour, wherein the first segment with the one end portion with a to be disposed of by oil Assembly connected and with the other directed to the pipe socket end section within the free interior of the second Segmentes is arranged and wherein the arranged one inside the other Sections are concealed together by the third segment, which coincides with the an end portion on the outer contour of the first segment above the cup-shaped contour of the second segment and with the other end portion on the outer contour of the pipe socket is applied. Advantageous embodiments are the subject of the dependent claims, whose Features in the embodiment described in more detail become.
Somit wird eine Baugruppe zur Ölrückführung an einer Brennkraftmaschine geschaffen, mit der in vorteilhafter Weise mit geringem Herstellungs-, Montage- und Kostenaufwand eine Siphonwirkung erzielbar ist. Diese technische Lösung kann sowohl zur Erstausstattung als auch zur Nachrüstung von Brennkraftmaschinen verwendet werden. Dabei ist ein wesentlicher Vorteil, dass die ohnehin an der Brennkraftmaschine verfügbaren Anschlussteile (Rohrstutzen und dergleichen) für eine Zuordnung dieser Baugruppe mit den erfindungsgemäß ausgestalteten drei Segmenten nicht geändert werden müssen.Thus, an assembly for Ölrückfüh tion created on an internal combustion engine, with the advantageously with low manufacturing, assembly and cost a siphon effect can be achieved. This technical solution can be used both for the initial equipment and for retrofitting of internal combustion engines. It is a significant advantage that the already available on the internal combustion engine connecting parts (pipe socket and the like) for an assignment of this module with the inventively designed three segments need not be changed.
