Description

Durch das Patent 671975 ist ein Membrandruckregler für Vergaser von Brennkraftmaschinen mit unter Gewicht- und Federbelastung stehender, das Brennstoffzulaßventil steuernder Membran unter Schutz gestellt, bei dem in bezug auf die NOrmallage der Boden eines Brennstoffraumes mit nur aufsteigenden Wänden und aufsteigenden Leitungen zur Vergasermischkammer von einer horizontalen Membran gebildet wird, die unter der in bezug auf die Einwirkung der Brennstoffsäule zwischen Düsenmündung und Membran entlastenden Wirkung eines Gegengewichtes und ihm entgegenwirkenden belastenden Druck einer Feder steht, deren Vorspannung von solcher Größe ist, daß in allen Lagen der Maschine durch die aus Gewicht und Federspannung resultierende Kraft sowohl eine genügend gleichmäßige lagenunabhängige Belieferung der Maschine mit Brennstoff als auch ein sicherer Abschluß des Brennstoffzuflusses bei Stillstand erreicht wird.By patent 671975 is a diaphragm pressure regulator For carburettors of internal combustion engines with weight and spring loading, the fuel admission valve Controlling membrane placed under protection in relation to the NOrmallage the floor of a fuel room with only ascending walls and ascending lines to the carburetor mixing chamber from a horizontal membrane is formed, which is under the with respect to the action the fuel column between the nozzle orifice and the membrane has a relieving effect Counterweight and it is counteracting onerous pressure of a spring whose Preload of such magnitude is that in all positions of the machine by the out Weight and spring tension resulting force both a sufficiently even position-independent supply of the machine achieved with fuel as well as a reliable termination of the fuel flow at standstill will.

Die Erfindung betrifft eine Verbesserung des durch das Hauptpatent geschützten Reglers und besteht darin, daß das in bezug auf die Einwirkung der Brennstoffsäule zwischen Düsenmündung und Membran entlastend wirkende Gegengewicht durch eine Feder ersetzt ist, die zusammen mit der entgegenwirkenden Feder außerhalb des Brennstoffraumes in einem gemeinsamen Gehäuse untergebracht ist. Durch diese Einrichtung wird der Aufbau des Membrandruckreglers gemäß dem Hauptpatent wesentlich vereinfacht.The invention relates to an improvement of the regulator protected by the main patent and consists in that in relation to the action of the column of fuel between Nozzle orifice and diaphragm relieving counterweight is replaced by a spring, which works together with the counteracting Spring is housed outside the fuel chamber in a common housing. Through this facility will the structure of the diaphragm pressure regulator according to the main patent is significantly simplified.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel veranschaulicht. Hierin entsprechen die Teile 1 bis 15 und 20 bis 25 den entsprechend bezeichneten Teilen des Hauptpatents. Abweichend vom Hauptpatent ist das dort mit 16 bezeichnete Gegengewicht gemäß der vorliegenden Erfindung durch eine Feder 16' ersetzt, die zusammen mit der Gegenfeder 13 auf der unteren Seite der Membran 3 außerhalb des Brennstoffraumes 1 in einem besonderen Federraum untergebracht ist. Dabei stützt sich die Feder 16' mit ihrem unteren Ende gegen einen Vorsprung 26 innerhalb des in der Mitte zu einem Federgehäuse erweiterten Deckels 4 ab, während sie sich mit ihrem oberen Ende unmittelbar an den unteren Membranteller 8 anlegt. Die Gegenfeder 13 stützt sich dagegen, wie bei dem Hauptpatent, mit ihrem oberen Ende innerhalb des Federgehäuses gegen einen festen Vorsprung ab, während sie mit dem unteren Ende auf einem Federteller 12 ruht, der mit der auf dem Führungszapfen 9 gleitenden und mit der Membran 3 dicht verschraubten Führungsbuchse 7 verbunden ist. Dabei kann, wie bei dem Hauptpatent, die Spannung der Feder 13 durch eine Stellmutter 11 reguliert werden.In the drawing, the invention is illustrated in one embodiment. Here in the parts 1 to 15 and 20 to 25 correspond to the corresponding parts of the Main patent. In contrast to the main patent, the counterweight labeled 16 is there replaced according to the present invention by a spring 16 ', which together with the Counter spring 13 on the lower side of the membrane 3 outside the fuel chamber 1 is housed in a special spring space. The spring 16 'is supported with her lower end against a protrusion 26 within the center to a spring housing extended cover 4, while its upper end rests directly on the lower diaphragm plate 8. the Counter spring 13 is supported against it, as in the main patent, with its upper end inside the spring housing against a fixed projection, while with the lower end rests on a spring plate 12, which with the sliding on the guide pin 9 and with the membrane 3 tightly screwed guide bush 7 is connected. As with the main patent, the The tension of the spring 13 can be regulated by an adjusting nut 11.
