Vorteile der Erfindungadvantages the invention
Das erfindungsgemäße Brennstoffeinspritzventil mit den Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass die Geometrie des Brennstoffeinspritzventils, insbesondere der Brennstoffkanäle, verbessert ist. Speziell eignet sich das erfindungsgemäße Brennstoffeinspritzventil auch für Anwendungen, bei denen ein hoher Druck des Brennstoffes erforderlich oder gewünscht ist. Ferner kann der Materialeinsatz hinsichtlich der gewünschten Festigkeit optimiert werden.The Fuel injection valve according to the invention with the features of claim 1 has the advantage that the geometry the fuel injection valve, in particular the fuel channels, improved is. In particular, the fuel injection valve according to the invention is suitable also for applications, where a high pressure of the fuel is required or desired. Furthermore, the use of material with regard to the desired Strength be optimized.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen des im Anspruch 1 angegebenen Brennstoffeinspritzventils möglich.By in the subclaims listed activities are advantageous developments of specified in claim 1 Fuel injection valve possible.
Vorteilhaft ist es, dass der erste Brennstoffkanal und/oder der zweite Brennstoffkanal zumindest im Wesentlichen geradlinig verläuft. Ferner ist es vorteilhaft, dass der zweite Brennstoffkanal den Kopplerraum mit einem Brennstoffraum verbindet und dass der zweite Brennstoffkanal an einer ebenen Mündungsfläche des Brennstoffraums in den Brennstoffraum mündet. Ein geradlinig verlaufender Brennstoffkanal, der beispielsweise als Bohrung ausgestaltet sein kann, hat den Vorteil, dass eine große mechanische Festigkeit erreicht werden kann, die auch hohen Brennstoffdrucken standhält. Insbesondere wird die Bildung von Rissen verhindert, da festigkeitsverringernde Verschneidungsstellen entfallen.Advantageous it is that the first fuel channel and / or the second fuel channel at least substantially rectilinear. Furthermore, it is advantageous that the second fuel channel the coupler space with a fuel space connects and that the second fuel channel at a flat mouth surface of the Fuel room opens into the fuel chamber. A straight line Fuel channel, which may be configured for example as a bore can, has the advantage of achieving a great mechanical strength can withstand high fuel pressures. Especially the formation of cracks is prevented because strength-reducing Divisions do not apply.
Vorzugsweise ist der Kopplerraum durch eine erste ebene Kopplerraumwand und eine der ersten Kopplerraumwand gegenüberliegende zweite ebene Kopplerraumwand begrenzt, an denen die ebenen Mündungsflächen vorgesehen sind. Der Kopplerraum kann dabei auch die Funktion eines zusätzlichen Speicherraumes für den Brennstoff übernehmen. Ferner ist es von Vorteil, dass die Brennstoffkanäle zumindest im Wesentlichen gegenüberliegend zueinander in den Kopplerraum münden, wodurch Beeinträchtigungen des Brennstoffflusses, insbesondere Verwirbelungen, vermieden sind und fertigungstechnische Vorteile bestehen. Die erste Kopplerraumwand und die zweite Kopplerraumwand können auch schräg zueinander liegen.Preferably is the coupler space through a first planar coupler space wall and a the first coupler space wall opposite second planar coupler space wall bounded at which provided the flat mouth surfaces are. The coupler space can also be the function of an additional Storage room for take over the fuel. Furthermore, it is advantageous that the fuel channels at least essentially opposite each other lead each other into the coupler space, causing impairments the fuel flow, in particular turbulence, are avoided and manufacturing advantages exist. The first coupler room wall and the second coupler space wall also oblique lie to each other.
Vorteilhaft ist es, dass die Brennstoffkanäle zumindest im Wesentlichen senkrecht zu der jeweiligen ebenen Mündungsfläche in den Kopplerraum münden. Dadurch kann die mechanische Festigkeit im Bereich der Mündungsfläche weiter verbessert werden. Allerdings bestehen auch dann Vorteile, wenn die Einmündung nicht senkrecht erfolgt.Advantageous is it that the fuel channels at least substantially perpendicular to the respective flat mouth surface in the Open coupler room. As a result, the mechanical strength in the area of the mouth surface continues be improved. However, there are advantages even if the confluence not vertical.
