Description
Entlüfter für das Kurbelgehäuse von Fahrzeug-Brennkraftmaschinen, insbesondere Flugmotoren Die dauernde Steigerung der Hubraum-Einheitsleistung (PS/i Hubraum) bei ortsbeweglichen Brennkraftmaschinen hat dazu geführt, daß durch das Schmieröl immer größere Wärmemengen abgeführt werden müssen. Hierzu genügt jedoch die abkühlende Oberfläche des Kurbelgehäuses und des Ölsumpfes nicht mehr, so daß man, insbesondere bei Flugmotoren, zur Anordnung besonderer vom Fahrtwind bestrichen-er ölkühler übergehen mußte. Diese lassen sich jedoch umgehen, wenn man durch das Kurbelgehäuse selbst einen kräftigen Luftstrom hindurchschickt, was sich in bekannter Weise dadurch bewerkstelligen läßt, daß man die Entlüfterstutzen mit einer Rohrleitung versieht, deren Mündung so in den Fahrt- oder Flugwind gestellt ist, daß eine kräftige Saugwirkung entsteht. Der Nachteil dieser Anordnung ist jedoch ein starker Olverlust, der durch die nachstehend beschriebene Neuerung vermieden wird.Breather for the crankcase of vehicle internal combustion engines, especially aircraft engines The constant increase in the unit capacity (HP / i Displacement) in portable internal combustion engines has led to the Lubricating oil have to dissipate ever larger amounts of heat. However, this is sufficient the cooling surface of the crankcase and the oil sump no longer, so that one, especially in the case of aircraft engines, for the arrangement of special ones from the airstream oil cooler had to pass. However, this can be bypassed if you go through the crankcase even sends a powerful stream of air through it, which is achieved in a known manner can be done by providing the vent nozzle with a pipeline, whose mouth is placed in the airstream or air wind that a powerful suction effect arises. The disadvantage of this arrangement, however, is a strong loss of oil, which is caused by the novelty described below is avoided.
Statt einfacher Prallflächen in einem Entlüftungsstutzen wird erfindungsgemäß ein mit Metallringen (Raschig-Ringen) oder einem anderen Füllstoff mit möglichst großer Oberfläche gefüllter Behälter vorgesehen, dessen unterer Siebboden kegelförmig mit der Spitze nach oben ausgebildet ist, so daß das an diesem herunterlaufende Öl, das sich an den Ringen niedergeschlagen hat, sich außen am Fuße des kegelförmigen Bodens sammelt und durch die Löcher des Siebbodens in einen Ringraum fließt, von dem aus es durch ein Röhrchen so ins Kurbelgehäuse zurückgeleitet wird, daß es von dem durch den Entlüfter gehenden Luftstrom nicht erneut mit hochgerissen wird. An der Oberseite des Stutzens ist ein in ähnlicher Weise wie unten kegelförmig ausgebildeter Siebboden angeordnet, dessen Spitze` nach unten gerichtet ist, so daß- das sich an diesem Boden niederschlagende Öl an der Spitze abtropft und auf die Ringfüllung fällt, von der es, wie vorher beschrieben, zum unteren Siebboden und von diesem zum Kurbelgehäuse zurückgeleitet wird. Das nach außen zu führende und Saugwirkung erzeugend in den Fahrtwind zu stellende Rohr wird an der oberen Öffnung des trichterförmigen Bodens angeschlossen.Instead of simple baffles in a ventilation nozzle, according to the invention one with metal rings (Raschig rings) or another filler with if possible Large surface filled container provided, the lower sieve bottom conical is formed with the tip upwards, so that the running down on this Oil that has deposited on the rings is on the outside at the base of the cone-shaped Soil collects and flows through the holes in the sieve bottom into an annulus from which it is guided back into the crankcase through a tube so that it is released from is not dragged up again by the airflow passing through the vent. At the top of the connecting piece is conical in a manner similar to the one below Sieve bottom arranged, the tip of which is directed downwards, so that the Oil precipitating at this bottom drips off at the top and onto the ring filling falls, from which it falls, as previously described, to and from the lower sieve tray is returned to the crankcase. That to the outside and suction generating in the airstream to be placed tube is at the upper opening of the funnel-shaped Connected to the ground.
