Zusatz zum Patent 287574.Addendum to patent 287574.
Patentiert im Deutschen Reiche vom 21. November 1913 ab. Längste Dauer: 20. Juni 1928.Patented in the German Empire on November 21, 1913. Longest duration: June 20, 1928.
Um bei dem Spritzvergaser nach Patent 287574 aucn im Leerlauf bei ganz geringer Drehzahl und bei geringen Leistungen, wie solche besonders bei Fahrzeugrnotoren bei den verschiedensten Drehzahlen verlangt werden, brauchbare Verhältnisse zu erzielen, empfiehlt es sich, außer dem freien Querschnitt des Saugkanals über der Brennstoffdüse, auch den freien Querschnitt in Höhe der Brennstoffdüse etwas, wenn auch in geringerem Maße, zu verkleinern, damit auch hier, wenn der obere Durchgangsquerschnitt schon sehr klein geworden ist, doch noch eine gewisse Sauggeschwindigkeit erreicht wird, welche ein gutes Gemisch von Luft und Brennstoff herstellen hilft. Dieses wird durch nachstehende Konstruktion erreicht:To AuCN to achieve i m idle at very low speed and at low power levels, as those are particularly required at Fahrzeugrnotoren in various speeds, useful ratios in the spray carburetor according to 287574, it is recommended that in addition to the free cross-section of the suction channel via the fuel nozzle also to reduce the free cross-section at the level of the fuel nozzle somewhat, albeit to a lesser extent, so that here, too, when the upper passage cross-section has already become very small, a certain suction speed is still achieved, which a good mixture of air and fuel manufacture helps. This is achieved by the following construction:
Der Drosselkegel f, durch welchen der freie Saugquerschnitt der Luftdüse g oberhalb der Spritzöffnungen und die Absaugöffnungen in der Haube d geregelt werden, ist an seinem unteren Ende mit einem Kranz k versehen, welcher mit einigen schmalen Stegen s mit dem unteren Rand des Kegels verbunden ist.The throttle cone f, which regulates the free suction cross-section of the air nozzle g above the spray openings and the suction openings in the hood d , is provided at its lower end with a ring k , which is connected to the lower edge of the cone with some narrow webs s .
Der äußere Durchmesser des Kranzes k soll dem in Höhe des Brennstoffspiegels engsten Durchmesser der Luftdüse g entsprechen, so daß er sich eben leicht einschieben läßt.The outer diameter of the ring k should correspond to the narrowest diameter of the air nozzle g at the level of the fuel level, so that it can be pushed in easily.
Der innere Durchmesser des Kranzes k muß nun so bemessen sein, daß bei der kleinsten Zylinderfüllung, d. h. bei der tiefsten Stellung des Drosselkegels, der freie Querschnitt zwischen dem Kranz k und dem Standrohr b nur so groß ist, daß an der Düse noch eine genügende Sauggeschwindigkeit erreicht wird, um ein brauchbares Gemisch zu erhalten. Zu beachten ist hierbei, daß der Kranz k in seiner Höhenlage entsprechend der inneren Form der Luftdüse so angeordnet wird, daß eine Verengung des Querschnitts an den Spritzöffnungen erst eintritt, wenn durch den oberen Rand des Kegels der freie Querschnitt oberhalb der Düse bereits so weit verkleinert ist, daß keine übermäßige Steigerung der Sauggeschwindigkeit an der Düse eintreten kann. Bei der Bestimmung der inneren Form der Luftdüse ist ferner darauf zu achten, daß, wenn der Kegel so weit gehoben ist, daß der freie Querschnitt zwischen oberen Rand des Kegels f und der Luftdüse g so groß ist als der Querschnitt in Höhe der Spritzöffnungen, auch der freie Querschnitt zwischen Luftdüse g und Kranz k einschließlich des freien Querschnittes zwischen Kranz k und Lufthaube d nicht kleiner ist, als der freie Querschnitt in Höhe der Spritzöffnungen bzw. des Brennstoffspiegels. The inner diameter of the ring k must now be dimensioned so that with the smallest cylinder filling, i.e. with the lowest position of the throttle cone, the free cross-section between the ring k and the standpipe b is only so large that a sufficient suction speed is still available at the nozzle is achieved to obtain a useful mixture. It should be noted here that the height of the ring k is arranged according to the inner shape of the air nozzle so that a narrowing of the cross section at the spray openings only occurs when the free cross section above the nozzle has already been reduced so much by the upper edge of the cone is that no excessive increase in suction speed can occur at the nozzle. When determining the inner shape of the air nozzle, care must also be taken that when the cone is raised so far that the free cross-section between the upper edge of the cone f and the air nozzle g is as large as the cross-section at the level of the spray openings, too the free cross section between the air nozzle g and ring k including the free cross section between ring k and air hood d is not smaller than the free cross section at the level of the spray openings or the fuel level.
Um eine zu plötzliche Querschnittsverminderung zu vermeiden, empfiehlt es sich, besonders bei Vergasern für größere Motoren, weil hier durch den Kranz k eine erhebliche Querschnittsverminderung erreicht werden muß, diesen Kranz an der Außenseite nach unten konisch zu machen, doch ist auch in diesemIn order to avoid too sudden a reduction in cross section, it is advisable, especially with carburetors for larger engines, because a considerable reduction in cross section must be achieved here by means of the ring k , to make this ring conical on the outside, but it is also in this one
Falle darauf zu achten, daß eine Verengung des Querschnitts an den Spritzöffnungen erst eintritt, wenn durch den oberen Rand des Kegels der freie Durchgangsquerschnitt oberhalb der Düse verringert wird.Trap to ensure that a narrowing of the cross-section at the injection openings only occurs when the free passage cross-section is above the upper edge of the cone the nozzle is decreased.
