Description

Flüssigkeitsgesteuerte Einspritzvorrichtung für Verbrennungskraftmaschinen. Es sind Einspritzverbrennungskraftmaschinen bekannt, bei welchen zwei Düsen vorgesehen sind, Von denen sich die eine im Sogen nannten Zündungsraum, die andere im eigentlichen Verbrennungsraum befindet. Von diesen Düsen wird die kleinere, in den Zündungsraum mündende zuerst mit Brennstoff von der Pumpe aus beschickt, die größere, in den Verbrennungsraum mündende dagegen erst geöffnet, nachdem die Zündungsdüse abgeschaltet ist.Liquid-controlled injection device for internal combustion engines. Injection internal combustion engines are known in which two nozzles are provided are, of which one is called the ignition chamber, the other in the actual Combustion chamber is located. The smaller of these nozzles is in the ignition chamber the opening is first charged with fuel from the pump, the larger one is fed into the The combustion chamber opening, however, only opens after the ignition nozzle has been switched off is.

Die flüssigkeitsgesteuerte Einspritzvorrichtung gemäß der Erfindung ist für Verbrennungskraftmaschinen hoher Leistung, d. h. solchen mit großen Zylindermaßen, bestimmt und dadurch gekennzeichnet, daß in einer dem Verbrennungsraum benachbarten Kammer eine Anzahl von federbelasteten Nadelventilen angeordnet sind, die von Leerlauf bis Vollast in bestimmter Reihenfolge je nach der Druckgebung der Brennstoffpumpe zum Ansprechen gelangen.The fluid controlled injection device according to the invention is for high power internal combustion engines, i. H. those with large cylinder dimensions, determined and characterized in that in an adjacent to the combustion chamber Chamber a number of spring-loaded needle valves are arranged by idling up to full load in a certain order depending on the pressure applied by the fuel pump get to speak.

Das Ansprechen der einzelnen Nadelventile in der gewünschten Reihenfolge wird durch geeignete Wahl der dem Flüssigkeitsdruck ausgesetzten Querschnitte erzielt, während die auf Ventilschluß wirkenden Gegenkräfte durch Federn hervorgerufen werden, welche an den Nadeloberteilen angreifen.The response of the individual needle valves in the desired order is achieved by a suitable choice of the cross-sections exposed to the liquid pressure, while the opposing forces acting on the valve closure are caused by springs, which attack the needle tops.

Es kann aber auch eine gemeinsame Gegenfederanordnung für sämtliche Düsen vorgesehen werden.But it can also have a common counter-spring arrangement for all Nozzles are provided.

Die denn Flüssigkeitsdruck ausgesetzten Querschnitte und die Federbelastungen sind derart gewählt, daß die kleinste Düse nur zum Leerlauf dient, während die Düsen mit den größeren Durchflußquerschnitten in bestimmten Abstufungen, beispielsweise von Halblast bis Vollast, zur Wirkung gelangen.The cross-sections exposed to fluid pressure and the spring loads are chosen so that the smallest nozzle is only used for idling, while the nozzles with the larger flow cross-sections in certain gradations, for example from half load to full load, take effect.

Auf der Zeichnung ist ein Ausführungsbeispiel einer Einspritzvorrichtung gemäß der Erfindung dargestellt, und zwar zeigt Abb. z einen senkrechten Schnitt, Abb. 2 eine Oberansicht, wobei der Schnitt nach der Linie A-B in Abb. 2 geführt ist.The drawing shows an embodiment of an injection device shown according to the invention, namely Fig.Z shows a vertical section, Fig. 2 is a top view, the section being taken along the line A-B in Fig. 2 is.

In den Düsenkopf a, welcher durch die Leitung b den Brennstoff zugeführt erhält, sind die Nadelventile c, d, e, f und g eingesetzt, deren Querschnitte in Verbindung mit den Federbelastungen derart gewählt sind, daß unter dem ansteigenden Flüssigkeitsdruck zuerst die Düse c als Leerlaufdüse anspricht, bei Halblast sich die Düsen e und d nacheinander öffnen, während bei Vollast auch die Düsen f und g zur Wirkung gelangen. Selbstverständlich kann die Zahl, die Anordnung und die Ausbildung der Düsen sowie der Reihenfolge des Ansprechens bei verschiedenen Belastungen in verschiedenartiger Weise gewählt werden.In the nozzle head a, which receives the fuel supplied through the line b, the needle valves c, d, e, f and g are used, the cross sections of which are selected in connection with the spring loads such that the nozzle c as the first under the increasing liquid pressure Idle nozzle responds, at half load the nozzles e and d open one after the other, while at full load the nozzles f and g also take effect. Of course, the number, the arrangement and the design of the nozzles as well as the order of response can be selected in different ways under different loads.
