Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Vorrichtung zum Fördern von Kraftstoff aus einem Vorratsbehälter zu einer Brennkraftmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for conveying fuel from a reservoir to an internal combustion engine according to the preamble of claim 1.
Stand der TechnikState of the art
Aus der
Die bekannte Kraftstofffördervorrichtung ist jedoch komplex aufgebaut und somit sowohl kostenintensiv als auch fehleranfällig.However, the known fuel delivery device is complex and thus both costly and error prone.
Offenbarung der ErfindungDisclosure of the invention
Es wird eine Vorrichtung zum Fördern von Kraftstoff vorgeschlagen, die statt der bei herkömmlichen Kraftstofffördervorrichtungen verwendeten Rückschlagventile ein Membranventil aufweist. Ein solches Membranventil kann eine flexible Membran aufweisen, die an ihrem Außenumfang in einer Treibleitung, an der eine Saugstrahlpumpe angeschlossen ist, gehalten ist. In einem Zentralbereich der Membran können ein oder mehrere Schlitze derart ausgebildet sein, dass einander entlang eines Schlitzes gegenüberliegende Flanken der Membran abhängig von einem auf die Membran wirkenden Druck entweder in Anlage zueinander liegen können und somit die von der derart geschlossenen Membran verschlossene Treibleitung abdichten, oder, bei einem höheren Druck, derart auseinander gespreizt werden, dass sich eine Öffnung zwischen den gegenüberliegenden Flanken der Membran bildet, so dass die Treibleitung freigegeben ist und Kraftstoff hindurchströmen kann.It is proposed a device for conveying fuel, which has a diaphragm valve instead of the check valves used in conventional fuel delivery devices. Such a membrane valve may have a flexible membrane, which is held on its outer periphery in a tether to which a suction jet pump is connected. In one central region of the membrane, one or more slits can be formed such that opposite flanks of the membrane along a slot can either lie in contact with one another depending on a pressure acting on the membrane and thus seal the tether closed by the membrane thus closed, or at a higher pressure, are spread apart such that an opening forms between the opposite flanks of the diaphragm so that the tether is released and fuel can flow therethrough.
Ein vorbestimmter Mindestdruck, unterhalb dem das Membranventil die Treibleitung verschließt, kann dabei von einer Elastizität sowie einer Geometrie der Membran sowie des oder der darin ausgebildeten Schlitze abhängen. Diese Einflussgrößen können so gewählt sein, dass der zum Öffnen des Membranventils nötige Mindestdruck so eingestellt ist, dass der von der Förderpumpe in der Treibleitung generierte Druck größer als der vorbestimmte Mindestdruck ist, ein Druck aufgrund eines Unterschiedes eines Kraftstoffpegels innerhalb des Vorratsbehälters und eines Kraftstoffpegels innerhalb des Speicherbehälters jedoch kleiner als der Mindestdruck ist. Dadurch kann ein unerwünschtes Rückströmen von Kraftstoff während eines Stillstandes der Förderpumpe vermieden werden.A predetermined minimum pressure, below which the membrane valve closes the tether, may depend on an elasticity and a geometry of the membrane and of the slot (s) formed therein. These influencing variables can be selected such that the minimum pressure required to open the diaphragm valve is set so that the pressure generated by the delivery pump in the treble line is greater than the predetermined minimum pressure, a pressure due to a difference of a fuel level within the reservoir and a fuel level within However, the storage container is smaller than the minimum pressure. Thereby, an undesirable backflow of fuel during a standstill of the feed pump can be avoided.
Das Membranventil kann eine dünne, flexible Gummimembran aufweisen. Eine solche Gummimembran kann kostengünstig hergestellt werden und ist ferner resistent gegen Kraftstoff.The diaphragm valve may have a thin, flexible rubber membrane. Such a rubber membrane can be manufactured inexpensively and is also resistant to fuel.
Das Membranventil kann abhängig von den gewünschten mechanischen Eigenschaften eine flache oder eine gewölbte Membran aufweisen. Eine flache Membran dürfte einfach und günstig zu fertigen sein. Eine gewölbte Membran dürfte einen im Vergleich zu einer flachen Membran geringeren Strömungswiderstand aufweisen.The diaphragm valve may have a flat or domed membrane depending on the desired mechanical properties. A flat membrane should be easy and cheap to manufacture. A domed membrane should have a lower flow resistance compared to a flat membrane.
