The tank has a main reservoir (1) that is connected to a second reservoir (13). The fuel pump (3) projects into the second reservoir, out of which it sucks the fuel and feeds it to the fuel supply pipe. The main reservoir is formed as a circular tank and the second reservoir as a reserve tank.

Description

Die Erfindung beschreibt einen Tank für Mitteldruckkraftstoffe mit In-Tank-Kraftstoffpumpe.The Invention describes a tank for medium pressure fuels In-tank fuel pump.

Mitteldruckkraftstoffe, üblicherweise Flüssiggas, auch LPG (Liquified-Petroleum-Gas) oder Autogas bezeichnet, ein Propan-Butan-Gemisch mit von Region zu Region unterschiedlichen Gemischanteilen, sind solche Kraftstoffe, die eines relativ geringen Druckes (p < 30bar) bedürfen, um bei Normaltemperatur in flüssigem Aggregatzustand gespeichert werden zu können, bei Atmosphärendruck aber gasförmig ist, in Abgrenzung zu den bei Raumtemperatur und Atmosphärendruck flüssigen Kraftstoffen [„Niederdruckkraftstoffe"], wie Benzin, Diesel, Alkohole oder ähnliche. Dazu bedarf es druckfeste Tanks, die mit einigen Sicherheitseinrichtungen ausgestattet sind.Medium pressure fuels, usually LPG, also called LPG (Liquified Petroleum Gas) or LPG, a Propane-butane mixture with different from region to region Mixture shares, are such fuels, a relatively low pressure (p <30bar) need to at normal temperature in liquid Physical state can be stored at atmospheric pressure but gaseous is, unlike at room temperature and atmospheric pressure liquid Fuels ["low-pressure fuels"], such as gasoline, diesel, Alcohols or similar. This requires pressure-resistant tanks with some safety features are equipped.

Für Anwendungen, z.B. in Verbrennungskraftmaschinen, bei denen der Mitteldruckkraftstoff flüssig in eine Brennkammer eingebracht werden soll, hat es sich als vorteilhaft erwiesen, den Kraftstoff durch eine Pumpe im Tank fördern zu lassen, weil dadurch die Gefahr des Verdampfens auf dem Weg zum Brennraum wirkungsvoll und mit geringem Aufwand unterbunden werden kann.For applications, e.g. in internal combustion engines where the medium pressure fuel is liquid in a combustion chamber is to be introduced, it has proved to be advantageous proved to promote the fuel through a pump in the tank too because of the risk of evaporation on the way to Combustor be effectively and with little effort prevented can.

So bietet die Firma Vialle (NL) für Ottomotoren in Kraftfahrzeugen ein Einspritzsystem mit Flüssiggas an, bei dem das Flüssiggas flüssig in den Ansaugtrakt vor die Einspritzventile gespritzt wird (LPI-System). Zur Erzeugung des notwendigen Systemdruckes verwendet sie eine im Flüssiggastank untergebrachte Membranpumpe, die 5 bar Arbeitsdruck erzeugt.So offers the company Vialle (NL) for Gasoline engines in motor vehicles an injection system with LPG at which the liquefied gas liquid injected into the intake system in front of the injectors (LPI system). To generate the necessary system pressure, it uses an in Liquefied gas tank housed Diaphragm pump that generates 5 bar working pressure.

In der EP 0922 851 A2 ist ein Flüssiggastank beschrieben, in dem eine Kraftstoffversorgungseinheit eingebracht ist, die ebenfalls eine Kraftstoffpumpe enthält.In the EP 0922 851 A2 a liquefied gas tank is described in which a fuel supply unit is incorporated, which also contains a fuel pump.

In der DE 202 09 413.8 wird eine ähnliche Konfiguration wie in der EP 0922 851 A2 , angelehnt an bekannte Kraftstofffördermodule für Ottokraftstoffe, vorgeschlagen, wobei hier, im Unterschied zur EP 0922 851 A2 , der Wesensunterschied zu einem Kraftstofffördersystem mit Kraftstoffen, die bei Normaldruck und Normaltemperatur flüssig sind, konstruktiv berücksichtigt wird.In the DE 202 09 413.8 will have a similar configuration as in the EP 0922 851 A2 , based on known fuel delivery modules for gasoline, proposed here, in contrast to EP 0922 851 A2 , the constructive consideration of the essential difference to a fuel delivery system with fuels that are liquid at normal pressure and temperature.

Bei allen besteht das Problem, dass durch die runde geometrische Form des Hauptreservoirs eine exakte Messung des noch vorhandenen Kraftstoffes schwierig ist, zumal er ungehindert hin- und herschwappen kann, meist verbunden mit dem Problem, ein relativ großes Bauteil wie die Kraftstoffpumpe und ihre Anschlüsse reversibel in diese runde Struktur einzubringen und den dafür notwendigen Deckel so abzudichten, dass er bei den geforderten Drücken dicht bleibt.at all the problem is that by the round geometric shape of the main reservoir an exact measurement of the remaining fuel it is difficult, especially as he can sway unhindered, usually associated with the problem, a relatively large component such as the fuel pump and their connections reversible in this round structure and introduce the necessary lid To seal so that it remains tight at the required pressures.
