Description
Spritzvergaser mit einer in einer Hilfskammer angeordneten Brennstoffdüse und zwangläufig von der Gemischdrossel beeinflußter Regelung der Zusatzluft. Die Erfindung betrifft eine weitere Durchbildung des in dem Patent 346513 beschriebenen Vergasers für flüssige Brennstoffe.Injection carburetor with a fuel nozzle arranged in an auxiliary chamber and inevitably influenced by the mixture throttle control of the additional air. the The invention relates to a further implementation of that described in the '346513 patent Liquid fuel carburetor.
Die Verbesserung besteht darin, daß auch in die zweite Kammer Mischluft eingeführt wird, und daß diese Luftmenge mit Hilfe eines Schiebers zwischen Null und einem Höchstbetrage geändert werden kann, während der ersten Mischkammer, der Hilfskammer, eine von vornherein festgelegte unveränderliche Luftmenge zugeführt wird. Dadurch wird verhindert, daß auch bei ungeschicktester Handhabung der Einrichtung ein übermäßig schweres Gemisch erzeugt wird. Am besten geschieht dies in der Weise, daß zwei Reihen von Öffnungen für den Eintritt der Luft vorgesehen sind, von denen die eine Reihe verschließbar, die andere Reihe dagegen bezüglich ihres: Durchtrittsquerschnittes konstant gehalten wird.The improvement is that mixed air also enters the second chamber is introduced, and that this amount of air with the help of a slide between zero and a maximum amount can be changed during the first mixing chamber, the Auxiliary chamber, a fixed amount of air that is fixed in advance is supplied will. This prevents even the most clumsy handling of the device an excessively heavy mixture is produced. This is best done in the way that two rows of openings are provided for the entry of the air, of which one row can be closed, the other row on the other hand with regard to its: passage cross-section is kept constant.
Die Vorrichtung ist .in beiliegender Zeichnung im Schnitt dargestellt.The device is shown in section in the accompanying drawing.
Der Vergaser besteht aus einem Oberteil I, . welches mit einer Vorwärmekammer versehen ist, dem bekannten Schwimmergehäuse III und dem Düsensystem II, welches gleichzeitig als Hilfsvergaser arbeitet.The carburetor consists of an upper part I,. which with a preheating chamber is provided, the known float housing III and the nozzle system II, which works as an auxiliary carburetor at the same time.
Die Arbeitsweise ist nun folgende: Beim Anlassen des Motors wird die Drosselklappe r durch einen Hebel so weit geöffnet, daß die Hauptnebenluftöffnungen a im Oberteil I durch den Vertikalschieber 3, wel-'eher gleichzeitig mechanisch von der Drosselklappe gesteuert wird, noch geschlossen bleiben. Sobald' der Motorkolben seine Saugwirkung beginnt, so kann der Unterdruck, welcher durch die Saugwirkung in dem Vergaseroberteil erzeugt wird, nur durch das Düsensystem II ausgeglichen -werden, da die Hauptluftöffnungen 2 im Oberteil geschlossen sind. Die atmosphärische Luft tritt nun durch die konstanten Öffnungen 4 in das Düsensystem ein, vermischt sich in der Düsenkammer 5 mit. dem Brennstoff, welcher durch die Saugwirkung das Steigrohr 6 verl'äßt, um als Gasgemisch aus der ringförmig gestalteten Düsenöffnung 7 herauszutreten. Die Dimensionen. sind vorteilhaft so bemessen, daß die Gemischmenge, -welche das Düsensystem abgibt, zum Anlassen und Leerlauf des Motors genügt.The mode of operation is now as follows: When the engine is started, the Throttle valve r opened by a lever so wide that the main secondary air openings a in the upper part I by the vertical slide 3, wel-'eher at the same time mechanically controlled by the throttle valve, remain closed. Once 'the engine piston When its suction begins, the negative pressure created by the suction is generated in the upper part of the carburetor, offset only by the nozzle system II -because the main air openings 2 in the upper part are closed. The atmospheric one Air now enters the nozzle system through the constant openings 4, mixed in the nozzle chamber 5 with. the fuel, which through the suction effect Riser pipe 6 leaves in order as a gas mixture from the annular nozzle opening 7 step out. The dimensions. are advantageously dimensioned so that the amount of mixture, -which the nozzle system emits, is sufficient to start and idle the engine.
Um nun für verschiedenartig wirkende Motoren aus demaDüsensystem, welches in diesem Falle als Anlaßvergaser arbeitet, das richtige Gasgemisch zu erhalten, so ist an demselben noch ein Drehschieber 8 angebracht, welcher die Öffnungen 9 verändert, durch -welche nun dem Anlasser mehr oder weniger Zusatzluft gegeben werden kann. Diese Zusatzluft beeinträchtigt den Brennstoffstrahl gewissermaßen bremsend und läßt daher die Brennstoffmenge in weitgehendstem Maße regulieren.In order now for differently acting motors from the nozzle system, which in this case works as a starter carburetor to get the right gas mixture, so a rotary slide valve 8 is attached to the same, which the openings 9 changed, by which more or less additional air is now given to the starter can. This additional air affects the fuel jet, so to speak, braking and can therefore regulate the amount of fuel to the greatest possible extent.
Während also die Öffnungen 9 durch den Schieber 8 geöffnet und geschlossen werden können, bleiben die Öffnungen 4. unverändert. Zwar umfaßt der Regulierungsschieber 8 auch m:it einer Hülse die Öffnungen 4, jedoch sind dieselben im, vorliegenden Falle in einem umlaufenden Ringkanal angeordnet, so daß ihr Querschnitt unverändert bleibt. Die vertikale Hülse, welche die Öffnungen 4 umfaßt, dient in dem Falle nur zur Regulierung des Drehschiebers. Wenn daher die Öffnungen 9 vollkommen geschlossen werden., so bleiben doch die Öffnungen 4 unverdeckt, so daß eine gewisse von vornherein festgelegte Luftmenge stets Zutritt hat.So while the openings 9 are opened and closed by the slide 8 the openings remain unchanged. Although the regulating slide includes 8 also with a sleeve, the openings 4, but the same are in the present one Trap arranged in a circumferential ring channel, so that its cross-section remains unchanged remain. The vertical sleeve, which comprises the openings 4, only serves in this case to regulate the rotary valve. Therefore, when the openings 9 are completely closed are., the openings 4 remain uncovered, so that a certain from the start fixed air volume always has access.
