Description
Vergaser für Brennkraftmaschinen Die Erfindung bezieht sich auf einen Vergaser für Brennkraftmaschinen mit schwenkbar gelagerten und den Durchtrittsquerschnitt der Mischkammer nach den Druckverhältnissen im Saugrohr der Maschine selbsttätig ändernden Klappen, bei welchen jede Klappe von einer im Schließsinne der Klappe' wirkenden Feder belastet ist. Bei der -bisher bekannten Anordnung dieser Feder ist deren eines Ende an dem Drehzapfen der Klappe aufgewickelt und mit diesem fest verbunden, während das andere freie Ende der Feder an der Klappe anliegt. Dieser Umstand bewirkt zufolge der ungleichen Beschleunigungsmassen von Klappe und Feder Sondef-schwingungen dieser Teile. Die Änderung des Durchtrittsquerschnittes der Mischkammer des Vergasers entspricht daher nicht mehr ausschließlich den Druckverhältnissen im Saugrohr der Maschine, sie ist vielmehr dadurch beeinträchtigt, daß die Richtungen der Schwingungen der Klappe und Feder zum Teil einander entgegengesetzt sind.Carburetor for internal combustion engines The invention relates to a Carburetor for internal combustion engines with pivotably mounted and the passage cross-section the mixing chamber automatically according to the pressure conditions in the suction pipe of the machine changing flaps, in which each flap is controlled by one in the closing direction of the flap ' acting spring is loaded. In the previously known arrangement of this spring is one end of which is wound on the pivot of the flap and firmly connected to it, while the other free end of the spring rests against the flap. This circumstance causes due to the unequal acceleration masses of the flap and spring, Sondef oscillations these parts. The change in the passage cross-section of the mixing chamber of the carburetor therefore no longer exclusively corresponds to the pressure conditions in the intake manifold Machine, rather, it is affected by the directions of the vibrations the flap and spring are partly opposite to each other.
Dieser Nachteil wird gemäß der Erfindung dadurch behoben, daß auch-das bisher freie, an der Klappe anliegende Ende der Feder mit der Klappe fest verbunden ist. Dadurch wird die Klappe mit der Feder zu einem Einheitskörper gemacht, der nur in eindeutigem Sinne schwingen kann und daher die beabsichtigte Regelung vollkommen erreicht.This disadvantage is eliminated according to the invention in that also-that hitherto free end of the spring resting against the flap is firmly connected to the flap is. This makes the flap with the spring into a unitary body that can only oscillate in a clear sense and therefore perfect the intended regulation achieved.
In der Zeichnung ist ein Ausführungsbeispiel der gemäß der Erfindung in der Mischkammer des Vergasers angeordneten Klappen dargestellt.In the drawing is an embodiment according to the invention Shown in the mixing chamber of the carburetor arranged flaps.
Abb. i ist ein Schnitt der Mischkammer nach einer zur Achse der Zerstäuberdüse senkrecht liegenden Ebene. Abb.2 und 3 sind Seitenansichten der schwenkbaren Klappe in der Richtung der Pfeile C, D aus Abb. i gesehen.Fig. I is a section of the mixing chamber looking one to the axis of the atomizing nozzle perpendicular plane. Figures 2 and 3 are side views of the hinged flap seen in the direction of arrows C, D in Fig. i.
Abb. 4. ist ein Schnitt nach der Linie A-B der Abb. 2.Fig. 4. is a section along line A-B of Fig. 2.
In der Mischkammer i ist die Zerstäuberdüse :2 quer gelagert. Jede Klappe 3 ist mit ihrem hülsenartigen Ende 4 auf dem Drehzapfen 5 schwenkbar gelagert. Die Drehzapfen 5 stecken fest in den Wänden der Mischkammer. Das hülsenartige Ende 4 der Klappe ist mit einem oder mehreren Ausschnitten 6 versehen, in welchem der auf dem Drehzapfen 5 aufgewickelte Teil 7 der Feder 8 liegt. Das eine Ende g der Feder ist mit dein Drehzapfen fest verbunden, z. B. liegt es in einem Ausschnitt io des Drehzapfens 5 (Abb. q.) .In the mixing chamber i, the atomizer nozzle: 2 is mounted transversely. Every The flap 3 is pivotably mounted with its sleeve-like end 4 on the pivot pin 5. The pivot pins 5 are firmly inserted in the walls of the mixing chamber. The sleeve-like end 4 of the flap is provided with one or more cutouts 6 in which the on the pivot 5 wound part 7 of the spring 8 lies. One end g the Spring is firmly connected to your pivot, e.g. B. it is in a cutout io of pivot 5 (Fig.q.).
Gemäß der Erfindung ist das andere Ende i i der Feder 8 mit der Klappe 3 bei 12 fest verbunden, z. B. durch Schweißen, Löten, Nieten u. dgl. Damit wird der eingangs erwähnte Effekt erzielt.According to the invention, the other end i i is the spring 8 with the flap 3 firmly connected at 12, e.g. B. by welding, soldering, riveting and the like the aforementioned effect is achieved.
