Description

Vorrichtung zum Entlüften des Kurbelgehäuses von unter einer Haube sitzenden Kraftwagen-Verbrennungsmotoren. Gegenstand der Erfindung ist eine Vorrichtung zur Entlüftung des Kurbelgehäuses von unter einer Haube sitzenden Verbrennungsmotoren für Kraftfahrzeuge.Device for venting the crankcase from under a hood seated vehicle internal combustion engines. The invention relates to a device for venting the crankcase of internal combustion engines sitting under a hood for automobiles.

Diese Entlüftung ist notwendig, damit die in dem mit dem Kurbelgehäuse in Verbindung stehenden Zylinder auf und nieder gehenden Kolben keinen Luftwiderstand finden, außerdem auch, umn zu verhindern, d.aß der Ölinhalt des Kurbelgehäuses durch heiße Öldämpfe erhitzt wird.This ventilation is necessary so that the one with the crankcase connected cylinder up and down piston no air resistance find, moreover, to prevent the oil content of the crankcase from leaking through hot oil vapors are heated.

Bei denn bisher üblichen, Entlüftungsvorrichtungen, die in sehr verschiedenen Formen ausgeführt worden sind, hat man. die entweichenden Gase in den Motorraum, also den Raum unter der Motorhaube, geleitet.In the case of venting devices that have been customary up to now, in very different ways Forms have been executed, one has. the escaping gases into the engine compartment, that is, the space under the hood.

Diese Ausführung hat den Nachteil, daß sämtliche Metallteile unter der Haube verschmutzt werden und an dieser Stelle eine starke Hitzeentwicklung hervorgerufen wird. Ein weiterer Nachteil ist der, daß die Gase durch die Öffnungen des Trittbretts beim Führersitz hindurch in das Wageninnere zu dringen suchen, weil durch den. Ventilator hinter dem Kühler ein Überdruck im Motorraum erzeugt wird und, die Luftabführung nach außen bei allen Kraftfahrzeugen wegen der engen Raumverhältnisse nur unvollkommen ist. Dieser Übelstand macht sich besonders bei geschlossenen Fahrzeugen sehr unangenehm bemerkbar und kann sogar zu Gesundheitsschädigungen bei dem Fahrer führen. Gemäß der Erfindung werden alle diese Mängel in sehr einfacher Weise dadurch beseitigt, daß man die Entlüftungsleitung nicht unter der Motorhaube münden läßt, sondern in die Außenluft, und zwar unterhalb des Motors, wo die Gase von einem starken Luftstrom .erfaßt werden. Dadurch wird erzielt, daß bei der Bewegung des Fahrzeuges die Gase aus dem. Kurbelgehäuse durch die Entlüftungsleitung abgesaugt werden.This version has the disadvantage that all metal parts under the hood are soiled and caused a strong heat build-up at this point will. Another disadvantage is that the gases through the openings in the footboard at the driver's seat to try to penetrate into the interior of the car, because through the. fan behind the radiator an overpressure is generated in the engine compartment and the air discharge to the outside in all motor vehicles only imperfectly because of the limited space available is. This inconvenience makes itself very uncomfortable, especially in closed vehicles noticeable and can even lead to damage to the health of the driver. According to the invention all these deficiencies are eliminated in a very simple manner by that you don't let the vent line open under the bonnet, but into the outside air, namely below the engine, where the gases from a strong air flow .be detected. This ensures that when the vehicle is moving, the gases from the. Crankcase can be sucked off through the ventilation line.

In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt.In the drawing, an embodiment of the invention is for example shown.

r ist das Kurbelgehäuse, das mit einer Öffnung 2 versehen ist, die durch eine Kappe 3 mit der Entlüftungsleitung in Verbindung steht. Diese besteht bei dem dargestellten Ausführungsbeispiel aus einem Kanal q., der in das Kurbelgehäuse mit eingegossen ist und auf dessen Unterseite in die Außenluft mündet.r is the crankcase, which is provided with an opening 2, the is in communication with the vent line through a cap 3. This exists in the illustrated embodiment from a channel q. Which in the crankcase is poured in and flows into the outside air on the underside.

Die Verbindung zwischen der Öffnung 2 und dem Kanal q. kann auch in anderer Weise hergestellt werden, z. B. kann auch dieser Teil mit angegossen sein.The connection between the opening 2 and the channel q. can also be in be made in another way, e.g. B. this part can also be cast on.
