Aus der EP 0 448 431 A1 ist ein Saugmodul bekannt, welches mittels Verbindungsstellen in Wirkverbindung mit einem Zylinderkopf bzw. einer Zylinderkopfhaube tritt. Ein Öleinfüllstutzen und eine Öleinfülleitung sind mit Kanälen des Zylinderkopfes zur externen Ölzufuhr verbunden. Eine Schraube stützt sich räumlich von der Öleinfülleitung getrennt über einen dem Saugmodul zugeordneten Vorsprung an einer Gegenfläche des Zylinderkopfes ab. Die beiden separat ausgeführten genannten Verbindungsstellen haben unnötige Mehrfachpassung, erhöhten Montageaufwand, ein großes Gewicht des Saugmoduls, bei jeweiliger Verschraubung Materialspannungen, zusätzliche Dichtungen oder eine aufwendige Fertigung oder Montage zur Folge.A suction module is known from EP 0 448 431 A1, which is operatively connected by means of connection points occurs with a cylinder head or a cylinder head cover. One oil filler neck and one Oil fill pipes are connected to the cylinder head channels for external oil supply. A The screw is spatially supported separately from the oil filler line via an assigned to the suction module Protrusion on a counter surface of the cylinder head. The two executed separately mentioned connection points have an unnecessary multiple fit, increased assembly effort great weight of the suction module, material tension for each screw connection, additional Seals or a complex manufacture or assembly result.

Der Ölabscheider 18 entnimmt durch die Ölentnahmeleitung 33 die ölhaltigen Durchblasgase aus dem Beruhigungsvolumen und trennt das Öl von den Gasen ab. Die Rückführung des in dem Ölabscheider 18 gesammelten Öls in den Ölkreislauf der Brennkraftmaschine erfolgt über eine vom Ölabscheider 18 ausmündende Ölrücklaufleitung 34, die mit einem nicht dargestellten Einlaßstutzen in der Zylinderkopfhaube 4 verbunden ist. Somit wird das vom Ölabscheider 18 abgeschiedene Öl wieder dem Ölkreislauf der Brennkraftmaschine zugeführt.The oil separator 18 is provided with an oil extraction line 33, which opens into the calming volume in the cylinder head cover 4. The oil separator 18 removes the oil through the line 33 blow-out gases containing oil from the calming volume and separates the oil from the gases. The return of the in the oil separator 18 oil collected in the oil circuit of the internal combustion engine via an oil return line opening out from the oil separator 18 34 with an inlet port, not shown, in the Cylinder head cover 4 is connected. So this is from the oil separator 18 separated oil back into the oil circuit of the internal combustion engine fed.

Im oberen Bereich des Ölabscheiders 18 befindet sich an seiner Ausströmseite 35, die der Öleinfülleitung 16 zugewandt ist, ein Anschlußstutzen 36, der über eine hier nicht dargestellte und als Schlauchverbindung ausgebildete Leitung mit dem Saugmodul 2 verbindbar ist. Die im Zylinderkurbelgehäuse vorhandenen und vom Ölabscheider 18 entölten Durchblasgase werden über diese Schlauchverbindung dem Saugmodul 2 und damit wieder dem Verbrennungsprozeß zugeführt.In the upper area of the oil separator 18 is on it Outflow side 35, which faces the oil filler line 16 Connection piece 36, the one not shown here and Line formed as a hose connection with the suction module 2 is connectable. The existing in the cylinder crankcase and from Oil separators 18 are de-aerated blow-by gases Hose connection to the suction module 2 and thus again the combustion process fed.

In einem weiteren Ausführungsbeispiel kann der Ölabscheider 18 auch als separates Bauteil vorgesehen werden. Ferner kann das Saugmodul 2 auch aus mehreren Bauteilen bestehen.In a further exemplary embodiment, the oil separator 18 can also be provided as a separate component. Furthermore, that Suction module 2 also consist of several components.
