Description
Schwimmerloser Saugvergaser mit Rundschieberdrosselung und gemeinsamem
Brennstoffkaliber für Leerlauf- und Hauptvergaser.
Gegenstand der Erfindung ist eine solche Ausbildung iderartiger Vergaser, daB sowohl der ,zunn Leierlanfvergaser führende Kanal als der zum Hauptvergaser führende durch ein gemeinsam :gesteuertes Ventil mit dem zum gemeinsamen Brennstofhkaliber führenden Kanal verbunden. werden kann. Beide Kanäle werden :beim Öffnen dieses Ventils., was durch etsprechende Drehung des Drosselrundschiebers erfolgt, mit der Brennstoffzufuhr zugleich verbunden oder beim Schltießen des Ventils von ihr abgeschnitten. Brei Nullstellung des DrosseIschizibers ist also die Brennstoffzufuhr zum Vergaser vollkommen abgesperrt.The subject of the invention is such a design iderartiger carburetor, that both the duct leading to the Leierlanf carburetor and the one to the main carburetor leading through a common: controlled valve with the common fuel caliber leading Channel connected. can be. Both channels are: at Open this valve. What by appropriate rotation of the rotary throttle valve takes place, connected to the fuel supply at the same time or when the valve is closed cut off from her. The fuel supply is therefore the main point of zeroing the throttle switch completely shut off to the carburetor.
Damit nun beim Ankurbeln dies Motors und Beginn der Offnung des Drosselschiebers und des durch diesen gesteuerten Breanstoftventils nicht lediglich Luft durch das Hauptspr.itzrohr. zur Leerlaufdüse angesaugt wird unter @`erhinderang der Sati:gwirkung auf den Brennstoff, ist im Spr:itz-rohr dies .Hauptvergasers ein Rückschlagventil vorgesehen. Dies verhindert den Eint.ritt von Tatft in den Brennstoffkanal, welcher das Spritzrohr des Hauptvergasers mit dem Brennstoffventil, also auch .mit der Leerlaufdüsie verbindet, wenn beim Ankurbeln die Saugwirkung des Motors itur auf letztere einwirkt, so,daß dann Brelins.toff aus @dein Behälter angesaugt werden muß. Zuglaich aber kann, :das Rückschlagventil (beispielsweise durch Ausbildung als ein im Spritzrohr des Hauptvergasers in der Höhenrichtung beweglicher, mit seitlichen Rillen oder Riefen für den Brennstoffdurchlaß versehener Zylinder) durch sein Gewicht und seine Form den Brelnstoffdurchfluß durch das Spritzrohr des Hauptvergasers der Motorgeschwindigkeit anpassen ,helfen, indem der Durchflußquersch:nitt an seinen Flachseiten entsprechend begrenzt ist.So now when cranking this engine and the start of the opening of the throttle slide and the breathtaking valve controlled by this not just air through the Main spray tube. to the idle jet is sucked in under @ `he ranks the sati: g effect on the fuel, the main carburetor in the spray pipe is a non-return valve intended. This prevents Tatft from entering the fuel channel, which the spray pipe of the main carburetor with the fuel valve, i.e. also with the idle nozzle connects when the suction of the motor acts on the latter when cranking, so that Brelins.toff must then be sucked out of @your container. But at the same time can,: the non-return valve (for example by training as a in the spray tube of the main carburetor in the vertical direction, with lateral grooves or Grooves for the fuel passage provided cylinder) by its weight and its Shape the fuel flow through the spray tube of the main engine speed carburetor adapt, help by adjusting the flow cross-section on its flat sides accordingly is limited.
Eine Ausführungsform des Erfindungs-`-egenstandes ist in der zugehörigen Zeichnung in Abb. i ini Querschnitt nach Schnittlinie I, 1I, 11I, I`- der Oberansicht nach Abb. 2 abgebildet.An embodiment of the subject of the invention is shown in the accompanying drawing in Fig. 1 in a cross-section along section line I, 1I, 11I, I`- the top view according to Fig. 2 .
Es bezeichnet a d,eit Brennstofzuführungskanal, h den Verbindungsflausch des Vergasers zum Motor und c den Luftansau:gkanal.It denotes a d, eit fuel supply duct, h the connecting loop the carburetor to the engine and c the air intake duct.
Der Brennstoff gelangt durch Kaliiber d zuan Ventile, «-elches durch Druckfede r f auf seinen Sitz gepreßt .und durch Drehung dies auf seinen Schaft g einwi.r,kenden Drosselrundscliiehiers l1 geöffnet wird,. Inn letzteren Fall werden die Brennstoffkanäle i, des Ieerlaufvergasers 7z und- l -des Spritzrohrs m ödes Hauptvergasers nni.t dein Brennstofzu£ührungakanal a unter Vermittlung der Düse d ti:Id cle5 @-entils e° in. Verbindung gebracht.The fuel arrives at valves through a caliber, which is pressed onto its seat by a pressure spring and, when turned, this is opened to act on its shaft and the round throttle valve is opened. In the latter case, the fuel channels i, of the idle gasifier 7z and l of the spray pipe are dull main gasifier nni.t your fuel supply channel a through the intermediary of the nozzle d ti: Id cle5 @ -entils e °.
Bei Beginn der Offinin:g des Dros,selrundschi°bers la wiird bei n zunächst nur ein so @@erin:Jer Luftquerschnitt freibegeben, daß eine kräftige Saugwirkung auf die Düse lz des Leerlaufv ergasers entsteht, sobald der Motor angekurbelt @wiird', wobei durch Aie Einwirkung des Drosselrundschiebers das Brennstoffventi.l e geöffnet wird. Damit nun in dieser Stellung nicht -lediglich Luft durch das Spritzrohr m des Hauptvergasers zur Düse k des Leerlaufvergasers angesaugt wird, ist in ersterem .ein Rücleschlaäventil o vorgesehen, welches au.s einem gerieften Zylinder p besteht. Dieser kann sieh in seiner Längsrichtung im Spritzrohr indes Hauptvergasers bewegen, so daß -er durch sein Gewicht mittels eines Kegielventils o den Luftzutritt in der eben bezeichneten Stellung des Drossel:run.dschiebers h verhütet.At the beginning of the offinin: g of the Dros, selrundschi ° bers la wi becomes at n at first only a so @@ erin: Jer air cross-section released that a powerful suction effect on the nozzle lz of the idle carburetor occurs as soon as the engine @wiird ', whereby the fuel valve is opened by the action of the rotary throttle valve will. So that now in this position not only air through the spray tube m of the main carburetor is sucked in to nozzle k of the idle carburetor, is in the former .A Rücleschlaäventil o is provided, which consists of a grooved cylinder p. This can move in its longitudinal direction in the spray pipe in the main carburetor, so that -he's weight by means of a cone valve o the air inlet in the Throttle position just described: round slide h prevented.
Bei weiterer Öffnung des letzteren hebt er sich aber entsprechend der auf dass Spritzrohr in des Hauptvergasers einwirkenden Saugwirkung mehr oder weniger an, bis seine obere, flache oder :gewölbte Fläche gegen das obere Ein@satzspritzrohr. q anschlägt. Dies weist zum Zweck des Brennstoffdurchlasses auch bei anschlagemd-em Ventilzylinder p Ei-nkerbungen r auf.If the latter is opened further, however, it rises accordingly the suction effect acting on that spray pipe in the main carburetor more or less until its upper, flat or: curved surface against the upper insert spray tube. q strikes. This points to the purpose of the fuel passage even with abschlagemd-em Valve cylinder p notches r open.
