  Ventilator zur   Spüllufterzeugung   für   Zweltpkt-Verbrennungskraftmaschinen.   
 EMI1.1 
 Stirnkurbel angetrieben. Statt dieser Kolbengebläse sind auch   Hochdruckventilatoren   verwendet worden, die entweder durch einen besonderen Elektromotor oder durch die verlängere Kurbelwelle unter Einschaltung einer doppelten Übersetzung angetrieben wurden. 



   Gemäss der Erfindung wird der Ventilator im Unterteil des Kurbelgehäuses auf einer lotrechten, von der   Maschinenwelle   unmittelbar angetriebenen Welle angebracht. Diese Anordnung ermöglicht eine einfache und billige Bauart, die sich insbesondere für Flugzugmaschinen eignet. 



   In der Zeichnung ist eine Zweitakt-Verbrennungskraftmaschine gemäss der Erfindung in einer beispielsweisen Ausführungsform dargestellt. 



   Die Zweitakt-Verbrennungskraftmaschine besitzt vier Zylinder a. Das Kurbelgehäuse ist unterteilt (b,   c)   und in seinem Unterteile c ist bei d der zur Erzeugung der Spülluft dienende Hochdruckventilator untergebracht. Dieser sitzt auf einer lotrechten, von der Maschinenwelle mittels der   Kegelräder   e, f unmittelbar angetriebenen Welle g. Die eingezeichneten Pfeile zeigen die   Zuströmungsrichtung   der Luft, die aus dem Ventilator mittels geeigneter Rohrleitungen zu den Maschinenzylindern weitergeleitet wird.

  Fan for generating scavenging air for mid-point internal combustion engines.
 EMI1.1
 Front crank driven. Instead of these piston blowers, high-pressure fans have also been used, which were driven either by a special electric motor or by the longer crankshaft with the engagement of a double transmission.



   According to the invention, the fan is mounted in the lower part of the crankcase on a vertical shaft driven directly by the machine shaft. This arrangement enables a simple and inexpensive design which is particularly suitable for aircraft tractors.



   In the drawing, a two-stroke internal combustion engine according to the invention is shown in an exemplary embodiment.



   The two-stroke internal combustion engine has four cylinders a. The crankcase is subdivided (b, c) and in its lower part c is housed at d the high-pressure fan used to generate the scavenging air. This sits on a vertical shaft g driven directly by the machine shaft by means of the bevel gears e, f. The arrows shown show the direction of flow of the air which is passed on from the fan to the machine cylinders by means of suitable pipes.
