die ε. B. die Kühlwirkung des Kühlwassers an den sehr heißen Auslaßventilen stark herabsetsen können. Aus diesem Grunde ist die vorgeschlagene Kühlwasserführung nur bei den Motoren iu verwenden, bei denen die Kühlwassersammelleitung höher oder numindestens in gleicher Höhe wie die Kühlwasserräume am Kurbelgehäuse angeordnet ist» damit sich in den Kühlwasserräumen bildende Luftblasen oder Dampf blasen entweichen können.the ε. B. can greatly reduce the cooling effect of the cooling water at the very hot exhaust valves. This is why Only use the suggested cooling water flow for engines iu, where the cooling water collecting line is higher or at least is arranged at the same height as the cooling water spaces on the crankcase »so that it is in the cooling water spaces forming air bubbles or vapor bubbles can escape.
Die Erfindung betrifft eine vorteilhafte weitere Ausbildung dss Gegenstandes des Patentes ..... (Patentanmeldung P 17 51 261.7-13). Sie besteht darin, das die Hubkolbenbrennkraftmaschinen stehende Reihenmotor·^ sind, bei denen die Sammelleitung an dem Kurbelgehäuse unterhalb der Zylinderkopfdichtung angebracht ist und deren Zylinderköpfe jeweils an der höchsten Stelle der KUhlwasserräuae mit einer Eatlüf tungebohrung versehen sind. Durch diese Maßnahme können die Vorteile, die sich durch das Angießen der KUhlwassersamaelleitung an das Kurbelgehäuse oder durch das lösbare Befestigen der Kühlwassersammelleitung am Kurbelgehäuse ergeben, auch bei stehenden Reihenmotoren erreioht werden. Durch die Einfachheit der am Kurbelgehäuse angegossenen Kühlwassersammelleitung ergibt sich eine erhebliche Material- und Koatentersparnis* Auserdea kann der damit verbundene Raumgewinn für die Luftleitung auegenutet werden, so daß die mit einer am Kurbelgehäuse befestigten KühlwasserSammelleitung ausgerüsteten stehenden Reihenmotoren einen kleineren Raumbedarf beanspruchen. Zusätslieh ergeben sich noch weitere Vorteile, die bereits im Hauptpatent erwähnt sind. So können beispielsweise die Sylinderköpfe ohne eine Demontage der KUhI-wasasrsammelleitung ausgewechselt werden.The invention relates to an advantageous further development dss subject of the patent ..... (patent application P 17 51 261.7-13). It consists in the reciprocating internal combustion engine standing in-line engine · ^ are in which the manifold is attached to the crankcase below the cylinder head gasket and its cylinder heads are each at the highest point the cooling water pipe is provided with a ventilation hole are. This measure can take advantage of the fact that the KUhlwassersamaelleitung is cast onto the crankcase or by detachably attaching the cooling water manifold to the crankcase, even with stationary in-line engines will. The simplicity of the cooling water collecting line cast onto the crankcase results in a considerable amount Material and coat savings * Auserdea can benefit from the associated Gaining space for the air line can be grooved so that the cooling water manifold attached to the crankcase Equipped standing in-line engines take up less space. In addition, there are other advantages, which are already mentioned in the main patent. For example, the cylinder heads can be used without dismantling the KUhI water collecting line be replaced.

Stelle der Kühlwaaserräume eines jeden Zylinderkopfes» wird vorteilhaft ein Ansammeln von Luftblasen beim Tüllen des Mo-: tors mit Kühlwasser oder ein Ansammeln von Daapfblasen verhindert. Es ist sehr zweckmäßig, wenn die Entlüftungsbohrung jeweils auf der der Sammelleitung entgegengesetzten Seite dea Zylinderkopfes angebracht ist, weil die Luftblasen dazu neigen, sich an denjenigen höchsten Stellen der KUhlwasserräume abzusetzen, die von dem KUhlwasserstroa nicht erfait oder nur wenig berührt werden.Place of the cooling water spaces of each cylinder head » advantageously an accumulation of air bubbles when filling the engine with cooling water or an accumulation of Daapfblasen prevents. It is very convenient if the vent hole is attached to the opposite side of the cylinder head from the manifold, because the air bubbles do so tend to settle at those highest points of the KUhlwasserstroa that are not covered by the KUhlwasserstroa or only touched a little.
Nach einem weiteren vorteilhaften Merkmal der Erfindung können die Entlüftungebohrungen außerhalb dea Ventildeckels im Zylinderkopf angeordnet sein. Da die Entlüftungsbohrungen nach diesem Merkmal der Erfindung frei zugänglich am Motor angeordnet sind, lassen sich die KUhlwasserräume beim Auffüllen des Motors mit Kühlwasser sehr leioht entlüften.According to a further advantageous feature of the invention can the vent holes outside the valve cover in Be arranged cylinder head. Since the ventilation holes according to this feature of the invention are freely accessible on the engine the cooling water spaces can be vented very easily when the engine is filled with cooling water.
Bei einer bevorzugten Ausführungsfora der Erfindung sind die Entlüftungsbohrungen über eine gemeinsame Entluftungsleitung miteinander verbunden. Durch diese Maßnahme ist es möglich, daß alle Zylinderköpfe gemeinsam entlüftet werden, da die Entlüfxungsleitung über den höchsten Stellen der Kühlwasserräume angeordnet ist und die sich in den KUhlwasserräumen sammelnde Luft von allein in die Entlüftungsleitung steigt. Die Stellung des Fahrzeugs und die Lage des Motors sind dabei unwesentlich, wenn die Entlüftungsleitung an ihren beiden Enden mit einer EntlUftungssohraube versehen ist.In a preferred embodiment of the invention, the ventilation bores are via a common ventilation line connected with each other. This measure makes it possible for all cylinder heads to be vented together, since the vent line is arranged above the highest points of the cooling water spaces and that collects in the cooling water spaces Air rises into the vent line by itself. The position of the vehicle and the location of the engine are immaterial, if the vent line is provided with a vent tube at both ends.

Zylinder 2 und den Zylinderkopf 3 eines stehenden Reihenmotors. Die Kü^hlwasserearamelleitung 4 ist seitlich an das Kurbelgehäuse 1 angegossen und liegt unterhalb der Zylinderkopfdichtung 5. Sie ist Über Kanäle 6 Kit den KühlwReeerräumen 7 des Zylinderkopfes 3 verbunden. Der Kühlwasserkreislauf ist durch·Pfeile 8 angedeutet. An der höchsten Stelle 9 des Zylinderkopfes 3 besteht leicht die Gefahr, daß sich dort Daapfblasen oder Luftblasen beim Füllen des Motors mit Kühlwasser ansammeln, da die Luftblasen naoh oben steigen und außerdem die Stelle 9 vom Kühlwasserkreislauf schlechter erfaßt wird. Eine sich an der höchsten Stelle 9 des Kühlwasserraumes 7 ansammelnde Luftblase würde eine sehr schlechte Kühlung des Ventiles 10 zur Folge haben. Deshalb ist an der höchsten Stelle 9 des Kühlwasserraumes 7 eine EntlUftungsbohrung 11 vorgesehen» in die eine EntlUftungssohraube 12 eingeschraubt ist« Die Entlüftungsbohrung 11 befindet aich außerhalb des Ventildeokeis 13, so daß sie im Bedarfsfalle sehr gut zugänglich ist. Die Entlüftungsbohrungen 11 sind über eine Entlüftungsleitung 14 miteinander verbunden. Die Entlüftungeleitung 14 ist nur im Querschnitt dargestellt.Cylinder 2 and the cylinder head 3 of a stationary in-line engine. The cooling water valve line 4 is on the side of the crankcase 1 and is below the cylinder head gasket 5. It is connected to the cooling water rooms 7 via ducts 6 kit of the cylinder head 3 connected. The cooling water circuit is indicated by arrows 8. At the highest point 9 of the cylinder head 3 there is a slight risk that there are Daapfblasen or air bubbles when filling the engine with cooling water accumulate, since the air bubbles rise near the top and also the point 9 is poorer covered by the cooling water circuit. An accumulating at the highest point 9 of the cooling water space 7 Air bubble would be a very poor cooling of the valve 10 result. Therefore, a vent hole 11 is provided at the highest point 9 of the cooling water space 7 » into which a vent tube 12 is screwed «the vent hole 11 is located outside of the valve ice 13, so that it is very easily accessible if necessary. the Vent bores 11 are provided via a vent line 14 connected with each other. The vent line 14 is only shown in cross section.
Ein weiterer Vorteil der Erfindung ist aus der Zeichnung zu entnehmen. Die an das Kurbelgehäuse 1 angegossene Kühlwasβer- «ammelleitung 4 kühlt zugleich den Ventiltrieb, so daß die StUeselstangen 15 einer kleineren Wärmedehnung unterworfen sind und das Ventilspiel 16 zwischen des Ventil 10 und den Kipphebel kaum verändert wird.Another advantage of the invention can be seen from the drawing. The cooling water cast on the crankcase 1 «Ammelleitung 4 also cools the valve train, so that the actuator rods 15 are subject to a smaller thermal expansion and the valve clearance 16 between the valve 10 and the rocker arm is hardly changed.
