Description

Brennkraftmaschine mit einem Drehkolbenladekompressor Bei Rotationskompressoren, die zum - Spülen von Verbrennungskraftmaschinen dienen, ist es bekannt, den Rotor mit einem einzigen Flügel zu versehen. Hierbei' ergibt sich. eine gewisse Periode, bei welcher sich der Flügel bewegt, ohne zu saugen und zu verdichten; während -dieser Periode ist die Verbindung zwischen Saug- und Druckseite des Rotationskompressors offen, so daß ein Zurückfluten der Ladeluft vom Arbeitszylinder in den Saugkanal des Kompressors stattfindet. Dies tritt in erhöhtem Maße bei überlademotoren -ein, bei welchen wähnend der Ladeperiode der Druck im Arbeitszylinder steigt.Internal combustion engine with a rotary piston charge compressor For rotary compressors, which are used for - flushing internal combustion engines, it is known the rotor to be provided with a single wing. Here 'results. a certain period, in which the wing moves without sucking and compressing; during this Period is the connection between the suction and pressure side of the rotary compressor open, so that the charge air flows back from the working cylinder into the suction channel of the compressor takes place. This occurs to a greater extent with overload engines, during which the pressure in the working cylinder rises during the loading period.

Es ist weiterhin bekannt, den Plügel des Ladekompressors so mit dem Arbeitszylinder periodisch in Zusammenhang zu bringen, daß der höchste Druck im Kompressor, welchen der Flügel erzeugt, mit dem Öffnen des Einlasses oder mit dem Beginn der Spül- oder Ladeperiode zusammenfällt. Diese Anordnung hat ebenfalls den Nachteil, daß bei ,einer bestimmten Dauer der Spül- oder Ladeperiode gegen Ende derselben wiedeT ein Zurückfluben der Ladeluft in den Kompressor stattfindet, da der Flügel im Kompressor die höchste Kompressionsstellung überschritten hat.It is also known that the plügel of the charge compressor so with the To bring working cylinder periodically in context that the highest pressure in the Compressor that the wing generates with the opening of the inlet or with the The beginning of the flushing or loading period coincides. This arrangement also has the Disadvantage that at, a certain duration of the flushing or loading period towards the end The same, as the charge air flows back into the compressor, takes place the wing in the compressor has exceeded the highest compression position.

Der Zweck der vorliegenden Eidung ist, die oben beschriebenen Nachteile zu beheben durch Anordnung eines zweiten Flügels, weicher dem ersten nacheilt und gegenüber dem ersten Flügel um einen Winkei versetzt ist, welcher der Nachlade- bzw. Überladeperiode des Arbeitszylinders annähernd entspricht, so daß bei Schluß der Nachlade- bzw. Überladeperiöde, also im Augenblick des höchsten .Druckes im Arbeitszylinder oder im Laderohr, der nacheilende Flügel sich im Kompressor in der Kompressionsperiode befindet, so daß ein Zurückfluten. oder auch nur teilweises Zurückfluten der Ladung verhindert wird.The purpose of the present divorce is to address the disadvantages described above to be remedied by arranging a second wing, which lags behind the first and is offset from the first wing by an angle, which is the reload or overload period of the working cylinder approximately corresponds, so that at the end the reloading or overloading period, i.e. at the moment of the highest pressure in the Working cylinder or in the loading pipe, the trailing wing in the compressor in the Compression period is so that a backflow. or only partially Backflow of the charge is prevented.

Auf .der Zeichnung ist ein Ausführungsbeispiel dargestellt, und zwar in der KompressorsteIlung bei Schluß der Nach- bzw. Überladep,eriode. Der sogenannte Nach- bzw. Überladeflügel eilt dem Spülflügel um den Winkel a nach. Durch die Anordnung des nacheilenden Flügels wird ein Zurückfluten in den Kompressor unmöglich gemacht, während bei Nichtvorhandensein dieses Nachladeflügels die Ladeluft durch den. Eimaß des Kompressors wieder ins Freie abströmen würde.On .der drawing an embodiment is shown, namely in the compressor position at the end of the recharging or overloading period. The so-called The reloading or transfer wing lags behind the flushing wing by the angle a. By the arrangement of the trailing vane is made impossible to flow back into the compressor, while in the absence of this reloading wing, the charge air through the. Eimß of the compressor would flow out into the open again.

Claims (1)

PATENTANSPRUCH-: Brennkraftmaschine mit einem Drehkolbenladekompressor, der statt je einer Schaufel für jeden Zylinder denen zwei besitzt, dadurch gekennzeichnet, daß die zweite Schaufel zum Nach- bzw. Überladen dient und der ersten um einen Wüikel nacheilt, der annähernd oder vollständig gleich dem Kurbelwinkel ist, der während der Nachlade- bzw. Überladeperiode zurückgelegt wird. PATENT CLAIM-: Internal combustion engine with a rotary piston charge compressor which has two instead of one vane for each cylinder, characterized in that the second vane is used for reloading or overloading and the first one lags behind by a step which is approximately or completely equal to the crank angle that is covered during the reloading or overcharging period.
