Description
Spritzvergaser Durch die Erfindung soll ohne Verwendung von Ventilen, Klappen, Luftdüsen oder Bternsdüsen eine selbsttätige Gemischregelung in dem Sinne erreicht werden, d,aß nicht bei niedriger Gasgeschwindigkeit zu armes, bei hoher Geschwindigkeit zu reiches Gernisch geliefert wird. Dieses Ziel wird erreicht durch Verwendung einer Spritzdüsenform, wie sie von Druckluftzerstäubern bekannt ist, nämlich einer solchen Form, daß der innere Rand des Düsenkanals, der an dieser Stelle den engsten Querschnitt hat, der Strömungsrichtung entgegen scharfkantig vorgezogen ist.Injection carburetor The invention is intended to be without the use of valves, Flaps, air nozzles or air nozzles an automatic mixture control in the sense can be achieved, d, did not eat too poor at low gas velocity, at high gas velocity Speed too rich Gernisch is delivered. This goal is achieved through Use of a spray nozzle shape, as it is known from compressed air atomizers, namely such a shape that the inner edge of the nozzle channel, which is at this point has the narrowest cross-section, preferred to be sharp-edged against the direction of flow is.
Fig. i zeigt eine Düse der bekannten Vergaser: Fig. 2 bis q. zeigen einige Drosseldüsen; Fig. 5 und 6 zeigen Drosseldüsen mit konischem Regulierstift; Fig.7 zeigt einen Drosseldüsensatz.Fig. I shows a nozzle of the known carburetor: Fig. 2 to q. demonstrate some throttle nozzles; Figures 5 and 6 show throttle nozzles with a conical regulating pin; 7 shows a throttle nozzle set.
Die Drosseldüsen (Fig. z bis 6) wirken in der Weise, daß sie bei niedrigem Unterdruck im Vergaser verhältnismäßig mehr Brennstoff, bei hohem Unterdruck dagegen weniger durchfließen lassen als die normale Düse nach Fig. i. Durch Hintereinandersehalten von mehreren Drosseldüsen wird eine erhöhte Drosselwirkung erzielt. Fig.7 zeigt mehrere Drosseldüsen in einem Düsenrohr zusammengebaut als Drosseldüsensatz.The throttle nozzles (Fig. Z to 6) act in such a way that they are at low Underpressure in the carburetor comparatively more fuel, with high underpressure on the other hand let flow through less than the normal nozzle according to Fig. i. By holding one behind the other by using several throttle nozzles, an increased throttling effect is achieved. Fig.7 shows several throttle nozzles assembled in a nozzle tube as a throttle nozzle set.
Die Einlaßkante sollte möglichst den engsten Querschnitt der Düse bilden; der für den brennstoffdurchfluß bestimmte Querschnitt sollte also von der Einlaßkante an zunehmen. Je schärfer die Einlaßkante ist, desto stärker ist die Drosselwirkung. Statt des Brennstoffs kann auch ein Gemisch von Brennstoff und Luft durch diese Düsen strömen. Die Art des Vergasers, die Anzahl und Anordnung der Düsen, die Art des Brennstoffes sind für den Erfindungsgedanken nicht maßgebend.The inlet edge should, if possible, have the narrowest cross-section of the nozzle form; the cross-section intended for the fuel flow should therefore depend on the Inlet edge to increase. The sharper the inlet edge, the stronger it is Throttling effect. Instead of the fuel, a mixture of fuel and air can also be used flow through these nozzles. The type of carburetor, the number and arrangement of the nozzles, the type of fuel are not decisive for the idea of the invention.
