Die Erfindung betrifft eine Entlüftungsvorrichtung für ölbeladene Gase einer Brennkraftmaschine, wobei die Entlüftungsvorrichtung eine zumindest abschnittsweise an einem Zylinderkopf der Brennkraftmaschine ausgebildete Entlüftungsleitung und an der Brennkraftmaschine eine Verbrennungsluft zuführende Ansauganlage vorgesehen ist, entsprechend dem einleitenden Teil des Anspruchs 1.The invention relates to a ventilation device for oil-laden gases Internal combustion engine, wherein the ventilation device at least in sections vent line formed on a cylinder head of the internal combustion engine and on the internal combustion engine is provided with an intake system supplying combustion air is, according to the introductory part of claim 1.

Bekannte Entlüftungsvorrichtungen dieser Art weisen eine die Entlüftungsgase aus dem Kurbelgehäuse absaugende Entlüftungsleitung und einen separaten Ölabscheider auf. Eine derartige Entlüftungsvorrichtung ist beispielsweise in der DE 39 18 785 A1 gezeigt, gemäß welcher Blow-by-Gase der Brennkraftmaschine vom Kurbelgehäuse durch einen Ölabscheider hindurch direkt der Ansauganlage zugeführt werden. Eine separate Entlüftungsleitung ist an dem Zylinderkopf der Brennkraftmaschine angeordnet und führt die dort abgesaugten Gase ebenfalls der Ansauganlage zu.Known ventilation devices of this type have a ventilation gases from the Crankcase exhaust ventilation line and a separate oil separator. Such a ventilation device is shown for example in DE 39 18 785 A1, according to which blow-by gases of the internal combustion engine from the crankcase through a Oil separators can be fed directly to the intake system. A separate Vent line is arranged on the cylinder head of the internal combustion engine and leads the gases extracted there also to the intake system.

Nachteilhafterweise sind derartige bekannte Entlüftungsvorrichtungen verhältnismäßig großvolumig und kompliziert ausgeführt, so daß sie bei beengten Einbauverhältnissen nicht ohne weiteres eingesetzt werden können.Such known venting devices are disadvantageously proportionate large-volume and complicated, so that they are available in tight spaces cannot be used easily.

Aufgabe der Erfindung ist es daher, eine Entlüftungsvorrichtung zu schaffen, welche kompakt und einfach aufgebaut ist.The object of the invention is therefore to provide a ventilation device which is compact and simple.

Diese Aufgabe wird bei einer Entlüftungsvorrichtung der eingangs genannten Art dadurch gelöst, daß zumindest ein Abschnitt der Entlüftungsleitung der Ansauganlage zugeordnet ist, wobei zumindest eine Gaseintrittsöffnung und eine Gasaustrittsöffnung dieses Abschnittes der Entlüftungsleitung in der Flanschfläche zwischen Zylinderkopf und Ansauganlage liegend ausgebildet sind. Durch diese erfindungsgemäße Anordnung des einen Abschnittes der Entlüftungsleitung in der Ansauganlage gestattet ist, die gesamte Entlüftungsvorrichtung kompakt auszubilden, wobei durch Entfall von externen Verschlauchungen und entsprechenden Verbindungsstellen und Konstruktionselementen die Entlüftungsvorrichtung montagefreundlich konzipiert ist.This object is achieved in a ventilation device of the type mentioned solved in that at least a portion of the ventilation line of the intake system is assigned, wherein at least one gas inlet opening and one gas outlet opening this section of the ventilation line in the flange surface between the cylinder head and intake system are horizontal. Through this arrangement according to the invention of a section of the ventilation line is permitted in the intake system To design the entire venting device compact, with the elimination of external  Tubing and corresponding connection points and construction elements the ventilation device is designed to be easy to install.

Vorteilhafterweise ist der der Ansauganlage zugeordnete Abschnitt der Entlüftungsleitung unter Ausnutzung eines ohnehin vorhandenen Bauraumes gebildet. Dieser Bauraum erstreckt sich vorzugsweise zwischen zwei vereinzelten Saugrohren der Ansauganlage, wobei dieser Bauraum vor der Montage der Ansauganlage an dem Zylinderkopf zunächst offen ist. Nach der Montage der Ansauganlage ist diese Öffnung des Abschnittes verschlossen, wobei diese Öffnung in der Flanschfläche liegt und vorzugsweise durch eine dem Zylinderkopf zugeordnete Wandung, welche ebenfalls in der Flanschfläche liegt in eine Gaseintritts- und eine Gasaustrittsöffnung unterteilt. Diese Unterteilung kann auch durch entsprechende Gestaltung einer zwischen Ansauganlage und Zylinderkopf liegenden Dichtung erzielt werden.The section associated with the intake system is advantageously the Vent line formed using an existing space. This installation space preferably extends between two individual suction pipes Intake system, this space before installing the intake system on the Cylinder head is initially open. After the installation of the intake system, this opening is of the section closed, this opening being in the flange surface and preferably by a wall assigned to the cylinder head, which is also in the flange surface is divided into a gas inlet and a gas outlet opening. This subdivision can also be made by designing a between Intake system and cylinder head lying gasket can be achieved.

Die über die Entlüftungsvorrichtung abgeführten, ölbeladenen Gase können nach dem Durchströmen der Entlüftungsleitung einem beispielsweise in einer Zylinderkopfhaube integrierten Entlüftungsventil bzw. einer Kombination aus Entlüftungsventil und Ölabscheider zugeführt werden. Eine erhöhte Vorabscheidung zu diesem Zwecke kann in weiterer vorteilhafter Ausgestaltung beispielsweise bereits in dem der Ansauganlage zugeordneten zweiten Abschnitt beispielsweise durch entsprechende gußtechnische Gestaltung erzielt werden.The exhausted, oil-laden gases can after the Flow through the ventilation line, for example in a cylinder head cover integrated vent valve or a combination of vent valve and Oil separators are supplied. An increased pre-separation for this purpose can in a further advantageous embodiment, for example already in that of the intake system assigned second section, for example, by appropriate casting technology Design can be achieved.

Fig. 1 eine schematisch im Schnitt dargestellte Entlüftungsvorrichtung gemäß der Erfindung. Fig. 1 is a schematically shown ventilation device according to the invention in section.

In Fig. 1 ist schematisch eine mit 10 bezeichnete Entlüftungsvorrichtung dargestellt, welche sich abschnittsweise in einem Zylinderkopf 12 sowie in einer Ansauganlage 8 einer Brennkraftmaschine erstreckt. Die Entlüftungsvorrichtung 10 wird im wesentlichen aus einer insgesamt mit 14 bezeichneten Entlüftungsleitung gebildet, wobei in Richtung des Strömungsverlaufes der Gase ein erster Abschnitt 141 der Entlüftungsleitung 14 im Zylinderkopf 12 ausgebildet ist, dann ein der Ansauganlage 8 zugeordneter zweiter Abschnitt 142 folgt und ein dritter Abschnitt 143 dieser Entlüftungsleitung 14 wiederum im Zylinderkopf 12 ausgebildet ist.In Fig. 1, a ventilation device designated 10 is shown schematically, which extends in sections in a cylinder head 12 and in an intake system 8 of an internal combustion engine. The ventilation device 10 is essentially formed from a ventilation line, generally designated 14, a first section 141 of the ventilation line 14 being formed in the cylinder head 12 in the direction of the flow of the gases, followed by a second section 142 assigned to the intake system 8 and a third section 143 this vent line 14 is in turn formed in the cylinder head 12 .

Die Ansauganlage 8 weist in an sich bekannter Weise einen luftverteilenden Sammelraum 16 und von diesem ausgehend vereinzelte, zu den Brennräumen der Brennkraftmaschine führende Saugleitungen 18 auf.In a manner known per se, the intake system 8 has an air-distributing collecting space 16 and, starting from this, individual suction lines 18 leading to the combustion chambers of the internal combustion engine.

Der Zylinderkopf 12 weist in dem der Ansauganlage 8 zugewandten Bereich einen Flansch 20 auf, während die Ansauganlage 8 in diesem Bereich einen korrespondierenden Flansch 22 aufweist, wobei beide Flansche 20 und 22 einer zwischen den beiden Bauteilen liegenden, gedachten Flanschfläche F zugewandt sind.The cylinder head 12 has a flange 20 in the area facing the intake system 8 , while the intake system 8 has a corresponding flange 22 in this area, both flanges 20 and 22 facing an imaginary flange surface F lying between the two components.

Zwischen zwei benachbarten Saugleitungen 18 verlaufen Rippen 24 in der Ansauganlage 8, so daß der zweite Abschnitt 142 zwischen zwei solchen Saugleitungen 18 und der Flanschfläche F zugewandt liegend ausgebildet ist.Ribs 24 run in the intake system 8 between two adjacent suction lines 18 , so that the second section 142 between two such suction lines 18 and the flange surface F is designed to face.

Im Zylinderkopf 12 ist im Bereich einer an die Flanschfläche F grenzenden Öffnung 26 des zweiten Abschnittes 142 eine ebenfalls an diese Flanschfläche F grenzende Wandung 28 derart angeordnet, daß die Öffnung 26 bezüglich der Richtung des Strömungsverlaufes der Gase in eine Gaseintrittsöffnung 30 und eine Gasaustrittsöffnung 32 unterteilt ist.In the cylinder head 12 , in the area of an opening 26 of the second section 142 bordering the flange surface F, a wall 28 also bordering this flange surface F is arranged such that the opening 26 is divided into a gas inlet opening 30 and a gas outlet opening 32 with respect to the direction of the flow of the gases is.

Der Zylinderkopf 12 ist gemeinsam mit der Ansauganlage 8 auf ein Kurbelgehäuse 34 der Brennkraftmaschine aufgesetzt. In diesem Kurbelgehäuse 34 ist eine Entlüftungsbohrung 36 angeordnet.The cylinder head 12 is placed together with the intake system 8 on a crankcase 34 of the internal combustion engine. A vent hole 36 is arranged in this crankcase 34 .

Der erste Abschnitt 141 der Entlüftungsleitung 14 verbindet im montierten Zustand diese Entlüftungsbohrung 36 mit der Gaseintrittsöffnung 30. Der zweite Abschnitt 142 ist als zwischen der Gaseintrittsöffnung 30 und der Gasaustrittsöffnung 32 liegender Strömungsweg für die Gase ausgebildet. Zwischen einer Deckfläche 38 des Zylinderkopfes 12 und der Wandung 28 liegend ist der dritte Abschnitt 143 ausgebildet, welcher unmittelbar an die Gasaustrittsöffnung 32 grenzt. Oberhalb der Deckfläche 38 erstreckt sich ein den bekannten Ventiltrieb einer Brennkraftmaschine aufnehmender Raum 40, welcher ebenfalls in an sich bekannter Weise von einer nicht gezeigten Zylinderkopfhaube überdeckt ist. Beispielsweise in diese Zylinderkopfhaube kann ein ebenfalls an sich bekanntes Entlüftungsventil für den genannten Gasstrom angeordnet sein; dieses Entlüftungsventil kann mit einem Abscheider für die in den Gasen enthaltenen Öltröpfchen kombiniert sein.The first section 141 of the vent line 14 connects this vent hole 36 to the gas inlet opening 30 in the assembled state. The second section 142 is designed as a flow path for the gases lying between the gas inlet opening 30 and the gas outlet opening 32 . The third section 143 is formed between a top surface 38 of the cylinder head 12 and the wall 28 , which directly adjoins the gas outlet opening 32 . Above the top surface 38 extends a space 40 which receives the known valve train of an internal combustion engine and which is also covered in a manner known per se by a cylinder head cover, not shown. For example, a ventilation valve for the gas flow mentioned can also be arranged in this cylinder head cover; this vent valve can be combined with a separator for the oil droplets contained in the gases.

Für eine verbesserte Abscheidung kann beispielsweise bereits in dem zweiten Abschnitt 142 durch entsprechende gußtechnische Gestaltung eine zwanghafte, labyrinthartige Umlenkung des Gasstromes erzwungen werden.For improved separation, for example, a compulsory, labyrinth-like deflection of the gas flow can already be forced in the second section 142 by appropriate casting design.
