Abstract
Description
Technisches GebietTechnical area
Die Erfindung geht aus von einer Steckpumpe nach der Gattung des Anspruchs 1.The Invention is based on a plug-in pump according to the preamble of the claim 1.
Stand der TechnikState of the art
Eine
solche Steckpumpe ist aus der
In Abhängigkeit von der Drehzahl benötigt eine Verbrennungskraftmaschine unterschiedlich große Kraftstoffmengen. Um bei allen Betriebszuständen hinreichende Kraftstoffmengen im Rail zur Verfügung zu haben, sind die Steckpumpen auf die Höchstleistung ausgelegt. Dies bedingt allerdings den Nachteil, dass zumindest im Teillastbereich überschüssige Kraftstoffmengen kontrolliert zurück in den Kraftstofftank geführt werden müssen, um Überdrücke in dem Kraftstoffsammler zu vermeiden. Dazu ist ein separates, elektrisch ansteuerbares Ventil erforderlich.In Depending on the speed requires an internal combustion engine different amounts of fuel. In all operating conditions sufficient fuel in the rail available have, the plug-in pumps are designed for maximum performance. However, this requires the disadvantage that at least in the partial load range excess Fuel levels checked back into the fuel tank must be guided to overpressures in the fuel collector to avoid. This is a separate, electric controllable valve required.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung mit den Merkmalen gemäß Anspruch 1 hat den Vorteil, dass bei Gewährleistung einer zuverlässigen Funktion de Verbrennungskraftmaschine ein separates Ventil zur Vermeidung von Überdrücken in dem Hochdrucksammler nicht mehr erforderlich ist. Der sich insgesamt ergebende Herstellaufwand wird dadurch reduziert.The inventive device with the features according to claim 1 has the advantage that under warranty a reliable function of the internal combustion engine a separate valve to avoid overpressure in the high pressure collector is no longer necessary. The total resulting manufacturing costs is reduced.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Steckpumpe angegeben.In the dependent claims are advantageous embodiments and further developments of the plug-in pump according to the invention specified.
Durch die Ausgestaltung nach Anspruch 2 wird bei einfacher Herstellbarkeit eine besonders zuverlässige Funktion und Langlebigkeit der Steckpumpe erreicht.By The embodiment according to claim 2 is simple to produce a particularly reliable function and longevity reached the plug-in pump.
Durch die Ausgestaltung nach Anspruch 3 hat den Vorteil, dass sich bei einfacher Herstellbarkeit funktionsbeeinträchtigende Dejustierungen zwischen dem Schließglied und seinem elektromotorischen Stellglied nicht ergeben können.By The embodiment according to claim 3 has the advantage that at easy manufacturability dysfunction impairing between the closing member and its electromotive Can not give actuator.
Die Ausgestaltung nach Anspruch 4 hat den Vorteil, dass das Schließglied durch das zugehörige Stellglied in bezug auf den Ventilsitz und in bezug auf den elektromotorischen Antrieb präzise geführt ist. Hierdurch ist nicht nur eine zuverlässige Funktion des Ventils an sich gewährleistet, die sich auf das korrekte Öffnen und Schließen bezieht, sondern auch eine besonders zuverlässige Betätigbarkeit durch den Elektromagneten.The Embodiment according to claim 4 has the advantage that the closing member by the associated actuator with respect to the valve seat and precisely with respect to the electric motor drive is guided. This is not just a reliable one The function of the valve itself ensures that is up the correct opening and closing refers, but also a particularly reliable operability through the electromagnet.
Die Ausgestaltung nach Anspruch 5 hat den Vorteil, dass extrem große Magnetkräfte von der Magnetspule auf die den zugehörigen Eisenkern bildende, ebene Platte übertragen werden können, mit der das Schließglied starr verbunden ist. Das Schließglied kann dadurch sehr feinfühlig betätigt und präzise gesteuert werden, was zuverlässig dazu beiträgt, kritische Überdrücke und damit druckbedingte Beschädigungen zu vermeiden.The Embodiment according to claim 5 has the advantage that extremely large Magnetic forces from the solenoid to the associated Iron core forming, flat plate can be transferred, with the closing member is rigidly connected. The closing element can be very sensitively operated and precise be controlled, which reliably contributes to critical overpressures and to avoid pressure-related damage.
Durch die Ausgestaltung nach Anspruch 6 ergibt sich der Vorteil einer besonders günstigen Gestaltbarkeit des benötigten Einbauraums. Dies ist von großer Bedeutung in Hinblick auf die kleinen Abmessungen einer Steckpumpe, die eine Integration des vorliegenden Sicherheitsventils bisher unmöglich erscheinen ließen.By the embodiment according to claim 6 gives the advantage of particularly favorable design of the required Installation space. This is very important in terms of on the small dimensions of a plug-in pump, which is an integration the present safety valve so far seem impossible left.
Durch die Ausgestaltung nach Anspruch 7 ergibt sich eine weitere Verkleinerung des benötigten Einbauraums und eine besonders hohe Montagefreundlichkeit. Ein fehlerhafter Zusammenbau ist so gut wie ausgeschlossen.By The embodiment according to claim 7 results in a further reduction the required installation space and a particularly high ease of installation. A faulty assembly is as good as impossible.
