Description

Vergaser. Es ist bekannt, den im Hauptsaugrohr von Vergasern angeordneten Düsenstöcken stromlinienförmigen Querschnitt zu geben.Carburetor. It is known that arranged in the main intake manifold of carburetors To give nozzle holders streamlined cross-section.

Demgegenüber kennzeichnet sich der Vergaser gemäß der Erfindung dadurch, daß der' Düsenstock als Drosselklappe von an sich bekannter flachgedrückter Tropfenform ausgebildet und mit mehreren parallelen, nahezu über die ganze Düsenstockbreite geführten Austrittsschlitzen für den Brennstoff versehen ist.In contrast, the carburetor according to the invention is characterized by that the 'nozzle assembly as a throttle valve of per se known flattened drop shape formed and with several parallel, almost over the entire width of the nozzle holder guided outlet slots for the fuel is provided.

Ein weiteres Merkmal des Vergasers besteht darin, daß die Austrittsschlitze für den Brennstoff in der Strömungsrichtung der Luft an Breite abnehmen.Another feature of the carburetor is that the exit slots for the fuel decrease in width in the direction of flow of the air.

Durch die Verwendung der Stromlinienform für die gleichzeitig als Düsenstock ausgebildete Drosselklappe wird ein leichtes Anspringen beim Anlassen erreicht und im übrigen Arbeiten gute Wirkungen erzielt, insbesondere hinsichtlich der elastischen Anpassung an die Drehzahl bzw. Leistung der Maschine.By using the streamlined shape for the same time as The throttle valve formed by the nozzle assembly is easy to start when starting achieved and achieved good effects in the rest of the work, especially with regard to the elastic adaptation to the speed or power of the machine.

Auf der Zeichnung ist ein derartiger Vergaser in Abb. i in Ansicht mit teilweisem Schnitt veranschaulicht. Abb.2 zeigt eine Draufsicht auf die Drosselklappe.In the drawing, such a carburetor is shown in Fig. I illustrated with partial section. Fig.2 shows a top view of the throttle valve.

Hierbei ist der eigentliche Vergaser mit a und das Hauptsaugrohr mit b bezeichnet. Der auf das Brennstoffzuführrohr c aufgesetzte Düsenstock d ist als Drosselklappe in flachgedrückter Tropfenform ausgebildet und ragt noch etwas in das hintere Ende der Luftdüse e. Die parallelen, nahezu über die ganze Düsenstückbreite geführten Austrittsschlitze f, g, h für den Brennstoff nehmen in der Strömungsrichtung der Luft an Breite ab und münden unter den Stufen i, h,1. Die Austrittsschlitze können statt, wie gezeichnet, senkrecht zur Luftströmung auch unter spitzen Winkeln hierzu angeordnet sein. Mit m ist der Austrittsschlitz für den Leerlauf, mit n die Defestigungsschraub.e für die Drosselklappe bezeichnet.The actual carburetor is denoted by a and the main suction pipe by b. The nozzle assembly d placed on the fuel supply pipe c is designed as a throttle valve in the form of a flattened drop and protrudes somewhat into the rear end of the air nozzle e. The parallel outlet slots f, g, h for the fuel, which run almost over the entire width of the nozzle piece, decrease in width in the direction of flow of the air and open out below the steps i, h, 1. Instead of being perpendicular to the air flow, as shown, the outlet slots can also be arranged at acute angles thereto. The outlet slot for idling is marked with m, the Defestigungsschraub.e for the throttle valve with n.
