Description
Spritzvergaser für Verbrennungsmotoren mit einem im Vergasergehäuse eingebauten, vom Regler beeinflußten Schieber. Die Erfindung betrifft Vergaser für Verbrennungsmotoren, bei welchen der vom Regler beeinflußte, zur Regelung der Gemischzufuhr dienende Schieber in das Vergasergehäuse eingebaut ist. Gemäß der Eriindung wird eine einfache und sehr gedrängte Bauart dadurch erreicht, daß der Schieber als Rundschieber mit diametralem Durchgang ausgebildet und über dem Zerstäuber angeordnet ist, und daß er von der Zerstäuberventilspindel diametral durchsetzt wird, die durch die Wanddurchbrechungen des Regelschiebers hindurch und oberhalb desselben im Vergasergehäuse geführt ist. Die Durchgangsöffnungen im Regelschieber nehmen dabei zweckmäßig im Oftnungsdrehsinne allmählich an Breite zu, um beim Öffnen des Schiebers langsame Zunahme der Zufuhrmenge und beim Schließen des Schiebers wieder langsame Abnahme zu erzielen, so daß je nach der Belastung des Motors eine Regelung der Brennstoffzufuhr n:it weitgehendster Genauigkeit ohne plötzliche Schwankungen erreicht wird.Injection carburetor for internal combustion engines with one in the carburetor housing built-in slider influenced by the controller. The invention relates to carburetors for Internal combustion engines, in which the one influenced by the controller, to regulate the mixture supply serving slide is built into the carburetor housing. According to the invention a simple and very compact design achieved in that the slide as a round slide is formed with a diametrical passage and is located above the atomizer, and that it is penetrated diametrically by the atomizer valve spindle, which is through the Wall openings of the control slide through and above it in the carburetor housing is led. The passage openings in the control slide expediently take the Often the direction of rotation gradually widens to slow when opening the slide Increase in the supply volume and slow decrease again when the slide valve is closed to achieve, so that depending on the load on the engine, a regulation of the fuel supply n: it the greatest possible accuracy is achieved without sudden fluctuations.
Weiterhin ermöglicht die Erfindung noch eine Veränderung des ringförmigen Durchganges zwischen der Prallfläche an der Zerstäuberventilspindel und der dazu konzentrisch angeordneten, sich nach oben konisch erweiternden Luftdüse dadurch, daß diese aus einem besonderen, im Vergasergehäuse achsial verschraubbaren und feststellbaren Einsatzstück besteht.Furthermore, the invention still allows a change in the ring-shaped Passage between the baffle on the atomizer valve spindle and the to it concentrically arranged air nozzle that widens conically upwards as a result, that this consists of a special, axially screwable and lockable in the carburetor housing Insert consists.
In der Zeichnung ist eine solche Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar zeigen die Fig. r und 2 senkrechte Schnitte durch den Vergaser, die rechtwinklig zueinander genommen sind, während Fig.3 eine Abwicklung des als Rundschieber ausgebildeten Regelschiebers zeigt.Such an embodiment of the subject matter of the invention is shown in the drawing shown, namely the Fig. r and 2 show vertical sections through the carburetor, which are taken at right angles to each other, while Figure 3 is a development of the as Round slide trained control slide shows.
In das Vergasergehäuse a mündet in -bekannter Weise von unten das Brennstoffrohr b, dessen radial rundum übereinander angeordnete Austrittsöffnungen c für den Brennstoff durch das Vergaserventil d gesteuert werden. Das Luftzuführungsrohr e ist parallel dem Vergaser an diesem angeordnet, der durch einen Durchlaß f dauernd mit ihm in Verbindung steht. Dieser mündet in den konzentrisch zur Brennstoffleitung b angeordneten Lufteintritt des Vergasers, der ein besonderes Rohrstück g bildet, welches achsial im Vergasergehäuse verschiebbar und mittels radialer Stellschraube h. nach der Einstellung feststellbar ist. Es ist in bekannter Weise nach oben konisch erweitert. In diese konische Erweiterung ragt die Prallfläche i an der Spindel k des ,Zerstäuberventils d derart, daß ihr. Rand mit dem Konus der Luftdüse einen ringförmigen Durchgangsschlitz für das Gasluftgemisch bildet. Die Weite dieses Ringschlitzes läßt sich durch das Verschrauben des Rohrstückes g im Vergasergehäuse regeln.In the known manner, the fuel pipe b opens into the carburetor housing a from below; The air supply pipe e is arranged parallel to the carburetor on the latter, which is permanently connected to it through a passage f. This opens into the air inlet of the carburetor, which is arranged concentrically to the fuel line b and which forms a special pipe section g, which is axially displaceable in the carburetor housing and by means of a radial adjusting screw h. can be determined after setting. It is flared upwards in a known manner. In this conical widening, the baffle surface i protrudes on the spindle k of the atomizer valve d in such a way that you. Edge with the cone of the air nozzle forms an annular passage slot for the gas-air mixture. The width of this annular slot can be regulated by screwing the pipe section g in the carburetor housing.
Über dem Zerstäuber ist der - als Rundschieber ausgebildete, vom Regler beeinflußte Regelschieber 1 angeordnet, und zwar derart, daß er von der Zerstäuberv entilspindel @r diametral durchsetzt wird. Der Schieberdurchgang ist diametral, und der Austrittsstutzen na liegt im rechten Winkel zur Zerstäuberventilachse. Ihm gegenüber befindet sich der Nebenlufteintritt iz, welcher durch eine Drosselklappe o regelbar ist, die sich zwischen dem Luftdurchlaß f und dem -Zusatzlufteintritt ia befindet und von Hand nach Bedarf einstellbar ist. Der als Rundschieber ausgebildete Regelschieber ist in seinem Gehäuse drehbar und besitzt zwei einander diametral gegenüberliegende Durchgangsöffnungen p und q, deren Form aus der Abwicklung (Fig.3) ersichtlich ist. Danach nimmt d:e Breite der ZJffnungen p und q im Öffnungsdrehsinne des Schiebers allmählich zu, so daß die Regelung der Zufuhr ganz allmählich erfolgt. Der Schieber L regelt zugleich auch den Eintritt von Zusatzluft, die sich innerhalb des Schiebers mit dem quer zu ihr einströmenden Gasluftgemisch gut mischt.Above the atomizer the - designed as a round slide, influenced by the regulator control slide 1 is arranged, in such a way that it is penetrated diametrically by the atomizer valve spindle @r. The slide passage is diametrical and the outlet nozzle na is at right angles to the atomizer valve axis. Opposite it is the secondary air inlet iz, which can be regulated by a throttle valve o, which is located between the air passage f and the additional air inlet ia and can be adjusted by hand as required. The control slide, designed as a round slide, can be rotated in its housing and has two diametrically opposed through openings p and q, the shape of which can be seen from the development (FIG. 3). Thereafter, the width of the openings p and q gradually increases in the direction of rotation of the slide, so that the supply is regulated very gradually. The slide L also regulates the entry of additional air, which mixes well within the slide with the gas-air mixture flowing in transversely to it.
Beim Ansaugen wird die Zerstäuberventilspindel angehoben und zugleich mit dem Brennstoff Luft angesaugt. Der angesaugte Brennstoff zerstäubt und mischt sich mit der Luft. Das Gemisch prallt gegen die Prallfläche v und tritt durch den Ringschlitz zwischen ihr und den konischen Teil des Rohreinsatzes g hindurch in den Rundschieber, um gemäß der Öffnung dieses Regelschiebers in den Austrittsstutzen in zu gelangen, wobei gleichzeitig in der bereits beschriebenen Weise bei mehr oder weniger geöffneter Drosselklappe ö noch Zusatzluft beigemischt wird.When sucking in, the atomizer valve spindle is raised and at the same time sucked in with the fuel air. The sucked in fuel atomizes and mixes get with the air. The mixture hits the baffle v and passes through the Ring slot between her and the conical part of the tube insert g through it the round slide in order to enter the outlet nozzle according to the opening of this regulating slide to get in, while at the same time in the manner already described with more or less open throttle valve or additional air is added.
