Description

Entlüftungsvorrichtung an Verbrennungskraftmaschinen. Durch die Entlüftungsstutzen, die an den Kurbelgehäusen. von Verbrennungskraftmaschinen vorgesehen sind, dringen namentlich bei Kraftmaschinen, die viel in staubiger Luft arbeiten, wie z. B. bei Lastkraftzügen: und Motorpflügen, nicht unerhebliche Staubmengen in das Innere des Kurbelgehäuses und führen zur schnellen Verunreinigung des Öles und zum schnellen Verschleiß der bewegten Teile. Die bisher vorgesehenen Siebe und sonstigen Abdeckungen für den Entlüftungsstutzen sind nicht geeignet, diese Übelstände zu beheben. Bekanntlich tritt in dem Entlüftungsstutzen in schnell wechselnder Folge eine Saug- und Druckwirkung auf. Bei der vorliegenden Erfindung wird nun davon ausgegangen, der Entlüftungsöffnung außerhalb des Stutzens eine entsprechend große Luftsäule vorzuschalten, die infolge der Saug und Druckwirkung in Schwingungen gerät und hierbei den größten Teil des der Luft beigemischten Staubes absondert. Bei entsprechend großer Luftmenge wird nämlich stets nur ein Teil der schwingenden Luftsäule in das Kurbelgehäuse hineingelangen.Ventilation device on internal combustion engines. Through the ventilation ports, those on the crankcases. are provided by internal combustion engines, penetrate especially with engines that work a lot in dusty air, such as B. at Trucks: and motorized plows, not inconsiderable amounts of dust in the interior of the Crankcase and lead to rapid contamination of the oil and rapid Wear of the moving parts. The sieves and other covers previously provided for the vent connection are not suitable for remedying these inconveniences. As is well known a suction and pressure effect occurs in the venting nozzle in rapidly changing succession on. In the present invention, it is now assumed that the vent opening a correspondingly large column of air to be connected upstream outside the nozzle, which as a result the suction and pressure effect starts to vibrate and thereby most of the releases dust mixed into the air. With a correspondingly large amount of air namely, only part of the oscillating air column can get into the crankcase.

Im wesentlichen besteht die Erfindung in einer den Entlüftungsstutzen lang übergreifenden, unten offenen Kappe oder Hülse, durch die ein Luftmantel um den Stutzen gebildet wird, der am unteren Ende mit der Außenluft und am oberen Ende mit dem Innern des Entlüfterstutzens,in Verbindung steht und in dem während des Betriebes der Maschine eine Luftsäule auf u'hd ab schwingt.Essentially, the invention consists in a vent nozzle long overarching cap or sleeve open at the bottom, through which an air jacket surrounds the nozzle is formed, which at the lower end with the outside air and at the upper end with the inside of the vent port, in communication and in which A column of air swings up and down while the machine is in operation.

Auf der Zeichnung ist die Vorrichtung nach der Erfindung in einer beispielsweisen Ausführungsform im senkrechten Schnitt dargestellt.In the drawing, the device according to the invention is in one exemplary embodiment shown in vertical section.

An einer Seitenwand a des Kurbelgehäuses ist der bekannte Entlüftungsstutzen b angebracht, dessen Öffnung c mit der Außenluft in Verbindung steht. Über diesen Stutzen b ist eine Kappe d gestülpt, die in geeigneter Weise, z. B. durch Aufschrauben, mittels eines Gewindeansatzes e mit dem Entlüftungsstutzen verbunden ist. In dem Gewindeansatz befinden sich Öffnungen f, durch die die Luft in den Stutzen b gelangen kann. Die von unten in die Kappe d eintretende Luft schwingt innerhalb der Kappe auf und nieder, so daß die enthaltenen Staubteilchen größtenteils ausgeschieden werden und nach unten fallen.On a side wall a of the crankcase is the known vent port b attached, the opening c of which is in communication with the outside air. About this Nozzle b is a cap d slipped over, which in a suitable manner, for. B. by unscrewing, is connected to the vent port by means of a threaded attachment e. By doing Threaded attachment there are openings f through which the air can get into the nozzle b can. The air entering the cap d from below vibrates within the cap up and down, so that the dust particles contained are largely eliminated and fall down.
