Description
Gegenstand der Erfindung ist eine Saugstrahlpumpe, bestehend aus einer Treibstrahldüse, einem Mischrohr, einer Ansaugöffnung, einer mit der Treibstrahldüse verbundenen Treibmittelleitung und einem in der Treibmittelleitung angeordneten Ventil. Verwendung finden Saugstrahlpumpen in Kraftstoffbehältern von Kraftfahrzeugen.object The invention is a suction jet pump, consisting of a propulsion jet, a Mixing tube, a suction port, one with the jet nozzle connected Treibmittelleitung and one in the propellant line arranged valve. Suction jet pumps are used in fuel tanks of Motor vehicles.
Derartige Saugstrahlpumpen werden in Kraftstoffbehältern eingesetzt, um Kraftstoff aus verschiedenen Bereichen des Kraftstoffbehälters einer Fördereinheit zuzuführen, welche den Kraftstoff aus dem Kraftstoffbehälter zu einer Brennkraftmaschine des Kraftfahrzeugs fördert. Zum Antrieb der Saugstrahlpumpe wird ein Teil des von der Kraftstoffpumpe geförderten Kraftstoffs abgezweigt und über die Treibmittelleitung der Saugstrahlpumpe zugeführt. Beim Start der Brennkraftmaschine soll die Kraftstoffpumpe möglichst schnell Kraftstoff in ausreichender Menge zur Brennkraftmaschine fördern. Hierzu ist in der Treibmittelleitung ein Ventil angeordnet, welches erst bei Erreichen des Systemsdrucks öffnet, so dass insbesondere bei einem Startvorgang der gesamte geförderte Kraftstoff zuerst der Brennkraftmaschine zugeführt wird.such Suction jet pumps are used in fuel tanks to fuel from different areas of the fuel tank of a conveyor unit supply, which the fuel from the fuel tank to an internal combustion engine of Motor vehicle promotes. To drive the ejector is a part of the fuel pump funded Fuel diverted and over the Fed medium line fed to the suction jet pump. At the start of the internal combustion engine should the fuel pump as possible fast fuel in sufficient quantity to the internal combustion engine promote. For this is located in the propellant line a valve, which only when system pressure is reached, so that in particular during a starting process, the entire subsidized fuel is first supplied to the internal combustion engine.
Zur Verbesserung des Startverhaltens des Kraftfahrzeugs ist es bekannt, den Druck in der Vorlaufleitung kurzfristig zu erhöhen. Hierzu wird die Leistung der Kraftstoffpumpe während des Startvorgangs kurzfristig erhöht. Damit wird jedoch die Wirkung des Ventils in der Treibmittelleitung aufgehoben, welches die Treibmittelleitung erst bei Erreichen des Systemdrucks freigeben soll. Das hat den Nachteil, dass infolge der Druckerhöhung das Ventil öffnet, welches die Saugstrahlpumpe für den Startvorgang von der Kraftstoffversorgung trennen soll. Somit gelangt ein Teil des Kraftstoffs zur Saugstrahlpumpe und steht nicht für die Brennkraftmaschine zur Verfü gung. Um dennoch eine ausreichende Versorgung der Brennkraftmaschine mit Kraftstoff während eines Startvorgangs sicherzustellen, muss die Kraftstoffpumpe so dimensioniert werden, dass sie neben dem erhöhten Bedarf an der Brennkraftmaschine auch die erhöhte Fördermenge für die Saugstrahlpumpe infolge des geöffneten Ventils liefert. Diese beiden erhöhten Fördermengen führen zu einer Überdimensionierung der Kraftstoffpumpe. Derartige Kraftstoffpumpen benötigen wesentlich mehr Bauraum und sind kostenintensiver.to Improving the starting behavior of the motor vehicle, it is known to increase the pressure in the supply line in the short term. For this the power of the fuel pump becomes short during the starting process elevated. However, this is the effect of the valve in the propellant line lifted, which the Treibmittelleitung only when reaching the Release system pressure. This has the disadvantage that as a result the pressure increase the valve opens, which the suction jet pump for to disconnect the starting process from the fuel supply. Consequently Part of the fuel reaches the suction jet pump and does not stand for the Internal combustion engine to avail supply. Nevertheless, to ensure adequate supply of the internal combustion engine Fuel during to ensure a startup, the fuel pump needs to do so be dimensioned that in addition to the increased demand for the internal combustion engine also the raised one output for the Suction jet pump as a result of the open Valve supplies. These two increased flow rates lead to an oversizing the fuel pump. Such fuel pumps require significantly more space and are more expensive.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Saugstrahlpumpe zu schaffen, die ausschließlich dann arbeitet, wenn das Kraftstoffversorgungssystem mit Systemdruck arbeitet.Of the Invention is therefore based on the object, a suction jet pump to create that exclusively then works when the fuel system with system pressure is working.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass in dem Gehäuse eine Durchströmöffnung angeordnet ist, dass ein Ventilkörper zu beiden Seiten der Durchströmöffnung derart angeordnet ist, dass die Durchströmöffnung sowohl einlassseitig als auch auslassseitig verschließbar ist, und dass mindestens eine Feder derart innerhalb des Gehäuses angeordnet ist, dass sie den Ventilkörper bis zum Erreichen des Systemdrucks in einer die Durchströmöffnung auslassseitig verschließenden Stellung hält.According to the invention Task solved by that in the case arranged a flow opening is that a valve body on both sides of the flow opening in such a way is arranged, that the flow-through both inlet side as well as on the outlet side is closable, and that at least a spring is disposed within the housing such that it the valve body until the system pressure is reached in an exhaust port on the outlet side occlusive Holding position.
Das in der Treibmittelleitung der Saugstrahlpumpe angeordnete Ventil ist im drucklosen Zustand geschlossen, indem die Feder den Ventilkörper auslassseitig in einer die Durchströmöffnung verschließenden Stellung hält. Sobald die Kraftstoffpumpe Systemdruck erreicht, ist die auf den Ventilkörper wirkende Kraft größer als die Federkraft, wodurch der Ventilkörper aus der die Durchströmöffnung auslassseitig verschließenden Stellung bewegt wird. Das Ventil ist somit geöffnet und Kraftstoff kann zur Saugstrahlpumpe gelangen. Steigt der Druck bei einem Startvorgang über dem Systemdruck, wird der Ventilkörper entgegen der Federkraft weiterbewegt, bis er in eine die Durchströmöffnung einlassseitig verschließenden Stellung ge langt, wodurch das Ventil schließt. Das erfindungsgemäße Ventil erlaubt den Betrieb der Saugstrahlpumpe in einem voreinstellbaren Druckbereich, wobei die Saugstrahlpumpe unterhalb und oberhalb dieses Druckbereichs abgeschaltet wird. Dadurch wird erreicht, dass die Saugstrahlpumpe ausschließlich unter Normalbedingungen arbeitet, während in kritischen Situationen, wo zuerst die Versorgung der Brennkraftmaschine mit Kraftstoff gewährleistet sein soll, der von der Kraftstoffpumpe geförderte Kraftstoff ausschließlich zur Brennkraftmaschine gelangt. Damit kann die Kraftstoffpumpe kleiner dimensioniert werden, da die Förderleistung der Kraftstoffpumpe nur noch bei Systemdruck von der Brennkraftmaschine und der Saugstrahlpumpe bestimmt wird, während bei einem Betrieb der Kraftstoffpumpe oberhalb des Systemdrucks die Förderleistung infolge des Abschaltens der Saugstrahlpumpe ausschließlich durch die Brennkraftmaschine bestimmt wird.The arranged in the propellant line of the suction jet pump valve is closed in the depressurized state, by the spring the valve body exhaust side in a position closing the flow-through opening holds. As soon as the fuel pump reaches system pressure, which acts on the valve body Force greater than the spring force, whereby the valve body from the outlet opening on the outlet side occlusive Position is moved. The valve is thus open and fuel can to the suction jet pump reach. If the pressure rises above the start-up pressure System pressure, the valve body becomes it is moved counter to the spring force until it is in a position closing the inlet opening on the inlet side reached, whereby the valve closes. The valve according to the invention allows the operation of the suction jet pump in a presettable Pressure range, the suction jet pump below and above this Pressure range is switched off. This ensures that the Suction jet pump exclusively works under normal conditions, while in critical situations, where first ensures the supply of the internal combustion engine with fuel should be, funded by the fuel pump fuel exclusively for Internal combustion engine passes. This can make the fuel pump smaller be dimensioned, since the delivery rate of the Fuel pump only at system pressure from the internal combustion engine and the ejector is determined while in an operation of the Fuel pump above the system pressure, the capacity due to the shutdown the suction jet pump exclusively determined by the internal combustion engine.
Die Durchströmöffnung gestaltet sich besonders einfach, wenn sie als Blende ausgeführt ist.The Through-flow designed especially easy when done as a shutter.
Ein zuverlässiges Abdichten wird gemäß einer anderen vorteilhaften Ausgestaltung dadurch erreicht, dass der Ventilkörper zwei Dichtelemente besitzt, welche einlassseitig und auslassseitig mit einem Dichtsitz an der Durchströmöffnung zusammenwirken.One reliable Caulking is done according to a other advantageous embodiment achieved in that the valve body two Has sealing elements, which inlet side and outlet side with a sealing seat on the flow-through cooperate.
Die Dichtelemente des Ventilkörpers bestehen in einer einfachen und damit kostengünstigen Ausbildung aus je einer Ringscheibe, welche am Ventilkörper angeordnet sind.The Sealing elements of the valve body consist of a simple and thus cost-effective training from one Ring disc, which on the valve body are arranged.
Der Aufbau des Ventilkörpers wird gemäß einer anderen Ausgestaltung vereinfacht, wenn die Dichtelemente bezogen auf die Strömungsrichtung zu beiden Seiten der Blende derart angeordnet sind, dass sie die Durchströmöffnung umgeben.The construction of the valve body is according to ei ner other embodiment simplified if the sealing elements are arranged relative to the flow direction on both sides of the aperture such that they surround the flow-through.
Eine definierte Position des Ventilkörpers in geöffneter Stellung bei Systemdruck wird in einer weiteren Ausgestaltung dadurch erreicht, dass zu der ersten Feder eine zweite Feder angeordnet ist, wobei die erste Feder auf den Öffnungsdruck des Ventils ausgelegt ist, und die zweite Feder eine weitere Bewegung des Ventilkörpers erst oberhalb des Systemdrucks zulässt. Auf diese Weise wird ein Bewegen des Ventilkörpers bei Systemdruck in der Offenstellung vermieden.A defined position of the valve body in open Position at system pressure is characterized in a further embodiment achieved that arranged a second spring to the first spring is, wherein the first spring is designed for the opening pressure of the valve is, and the second spring a further movement of the valve body only above the system pressure. In this way, a movement of the valve body at system pressure in the Open position avoided.
Die verwendeten Federn können sowohl Druckfedern als auch Zugfedern sein, wobei die Federn zwischen dem Gehäuse und dem Ventilkörper angeordnet sind.The used springs can be both compression springs and tension springs, the springs between the housing and the valve body arranged are.
Sofern Druckfedern verwendet werden, lassen sich diese in einer anderen Ausgestaltung auch zwischen dem Ventilkörper und der Durchströmöffnung anordnen. Zur besseren Führung und Aufnahme der Druckfeder ist in einer weiteren Ausgestaltung am Ventilkörper ein Absatz angeformt.Provided Compression springs are used, these can be in another Arrange design between the valve body and the flow opening. For better guidance and receiving the compression spring is in a further embodiment on the valve body a paragraph molded.
