Description
Für Autos mit ntto-""otar und im üeck untergebrachtem Sraftstofftank
eine Kraf tstof f-ilücklaufleitung vom Vergaser zum
Tank.For cars with ntto - "" otar and a fuel tank located in the rear, a fuel return line from the carburettor to the
Tank.
Alle Versuche, durch Manipulationen an den Vergasern von AutoMotoren, die vermittels einer Förderpumpe aus dem im Heck untergebrachten Tank mit Kraftstoff versorgt werden, dessen Verbrauch zu senken, sind durch folgendes Problem in Frage gestellt: All attempts by manipulating the carburettors of car engines by means of a feed pump from the one housed in the rear Tank supplied with fuel to reduce its consumption are challenged by the following problem:
Die Förderleistung der Pumpe ist der Umdrehungszahl der Kurbelwelle proportional. Per Hedarf ist bei gleicher Drehzahl recht unterschiedlich (z.T. Tergfahrt und leschleunigung - Talfahrt und Tremsen). Theoretisch sorgen Schwimmer und Schwimmernadel für den dem Hedarf entsprechenden Zufluß. Da aber die Antriebsverhältnisse der Pumpe so ausgelegt sein müssen, daß sie auch bei größtmöglichen Anforderungen genügend Kraftstoff fördert, kann bei zurückgehendem Tedarf der Schwimmer mit Schwimmernadel die Auswirkung des "iberdruckes der Förderpumpe nicht verhindern. The delivery rate of the pump is the number of revolutions of the crankshaft proportional. Per Hedarf is right at the same speed different (partly downhill travel and slow acceleration - downhill travel and tremors). Theoretically, the float and float needle ensure the influx corresponding to the hedarf. But since the drive ratios of the pump must be designed so that they also pumps enough fuel with the greatest possible demands, The swimmer with a float needle can do this if the demand is declining do not prevent the effect of the overpressure of the feed pump.
Dies zu korrigieren ist der ? ω e c k der Frfindunn, von der ein Anwendunqsbeispiel nachstehend beschrieben ist:Correct this is the? ω e c k the Frfindunn, from which a Application example is described below:
In der Mähe des Vergasers, zweckmäßig vor dem Schwimmergehäuse in Richtung der Frontseite des Fahrzeugs ist ein zusätzliches Gefäß angebracht, im Anwendungsbeispiel ein aufrechtstehender, mit festem Boden und abnehmbarem Deckel 5 versehener Zylinder 1 Fig. 1. Tn ihn führt nae!he dem 3oden die Leitung 2 von der Förderpumpe, etwas höher von ihm weg die Leitung 3 zum Schwimmergehäuse 7 und noch höher eine Leitung U von größerem Durchmesser als die vorgenannten, die zurückführend durch die Karosserie zur Oberseite des im Heck befindlichen Kraftstofftanks angeordnet ist.In the vicinity of the carburetor, expediently in front of the float housing in the direction of the front of the vehicle, an additional vessel is attached, in the application example an upright cylinder 1 Fig. 1 with a fixed base and removable cover 5 Line 2 from the feed pump, slightly higher away from it the line 3 to the float housing 7 and even higher a line U of larger diameter than the aforementioned, which is arranged leading back through the body to the top of the fuel tank located in the rear.

Zwei unerwünschte Begleiterscheinungen sind bei der beschriebenen Anordnung abzustellen.Two undesirable side effects are with the described To turn off the order.
1) Tm Deckel 5 des 7ylinders 1 muß unbedingt eine lelüftungsöffnunrj sein. Wenn diese fehlt, kann unter bestimmten Verhältnissen der Fall eintreten, daß der gesamte in den Zylinder gepumpte kraftstoff von der Rücklaufleitung k abgesaugt wird und das Schwimmergehäuse nichts erhält.1) The cover 5 of the cylinder 1 must have a ventilation opening. If this is absent, under certain circumstances it can happen that all of the fuel pumped into the cylinder is sucked off from the return line k and the float housing receives nothing.
2) lei gut gefülltem Tank wird bei starkem Hremsen oder Reschleunigen der Tankinhalt so intensiv nach vorne bzw. nach hinten gepreßt, daß dr rt ein großer Druck gegen die Tankoberseite, also auch gegen den Eingang der Rücklaufleitung k entsteht. Deren Wirkung wird umgekehrt und der jetzt von beiden Seiten erfolgende Zustrom läßt den Kraftstoff durch die Pelüftungsöffnunq im Zylinderdeckel 5 austreten und im Wageninneren verspritzen. 2) lei well filled tank is pressed in strong Hremsen Reschleunigen or the tank contents so intense forward or backward, that d r rt, a large pressure against the tank top, that is k is also formed to the entrance of the return line. Their effect is reversed and the inflow now taking place from both sides lets the fuel escape through the ventilation opening in the cylinder cover 5 and spray it inside the vehicle.
Die Teseitigung dieser Erscheinungen wird dadurch erreicht, daß sowohl unter die Telüftungsöffnung 6 im Deckel 5 des Zylinders als auch unter die Eintrittsöffnung der Rücklauf 1 eitung it in die obere liland des Tanks je ein Ventil angebracht wird, das eine nach unten gerichtete Strömung erlaubt und eine nach oben gehende verhindert.The elimination of these phenomena is achieved by that both under the ventilation opening 6 in the Cover 5 of the cylinder as well as under the inlet opening of the return line 1 it into the upper liland of the Tanks each have a valve that allows a downward flow and an upward flow prevented.

Jedes der beiden Ventile besteht aus einer runden Platte Θ, die mit einer über ihr liegenden Platte 9 mit größerem Durchmesser zentrisch verbunden ist. Diese dient zur Befestigung unter der oberen Tankuiand bzui. dem Deckel 5 des Zylinders 1. An der Ventilplatte θ ist nach unten peripheriegleich ein kurzes Rohrstück 1o angebracht. Die Halteplatte 9 hat in der Mitte eine Bohrung, die dem Innendurchmesser der jeweils eintretenden Leitung entspricht. Pie Bohrung der Ventilplatte 8 ist um die Stärke eines einzubringenden D-Finges 11 größer und etwas ausgekehlt. Each of the two valves consists of a round plate Θ with a plate 9 above it is centrally connected with a larger diameter. This is used for fastening under the upper tankuiand bzui. the cover 5 of the cylinder 1. On the valve plate θ, a short piece of pipe 1o is attached to the lower periphery. The holding plate 9 has in the middle a hole that corresponds to the inner diameter of the respective incoming line. Pie The bore of the valve plate 8 is larger by the strength of a D-finger 11 to be introduced and is somewhat grooved.
Mit dem notwendigen Abstand vom unteren Ende des Rohrstückes 1o ist eine Nut für einen Seegerring oder eine Federdrahtsperre 12 eingestochen. Zwischen diesem und der Ebene des O-Ringes bewegt sich ein rundes, relativ leichtes, mit k abstandhaltenden Nasen 1i» versehenes Blättchen 13 ab- und aufwärts je nach der Strömungsrichtung der ieweiliqen Medien.With the necessary distance from the lower end of the pipe section 1o, a groove for a Seeger ring or a spring wire lock 12 is pierced. Between this and the plane of the O-ring, a round, relatively light leaf 13 provided with k spacing noses moves down and up depending on the direction of flow of the respective media.
