Abstract
Filteranordnung für einen Brennstofftank, wobei das Filter für den von einer Brennstoffpumpe angesaugten Brennstoff durch bei Brennstoffbenetzung vorliegende Oberflächenspannung als Rücklaufsperre wirkt, wenn das Filter aus dem Brennstoff austaucht, dadurch gekennzeichnet, dass an der höchstgelegenen Stelle einer Filterkammer (5) eine von Brennstoff benetzte Entgasungsbohrung (7) angeordnet ist, die in eine Brennstoffvorratskammer (8) ausmündet.Filter arrangement for a fuel tank, the filter for the fuel drawn in by a fuel pump acting as a backstop when the filter emerges from the fuel due to surface tension when the fuel is wetted, characterized in that at the highest point of a filter chamber (5) there is a degassing hole wetted by fuel (7) is arranged, which opens into a fuel storage chamber (8).
Description
Die Erfindung betrifft eine Filteranordnung für einen Brennstofftank, wobei das Filter für den von einer Brennstoffpumpe angesaugten Brennstoff durch bei Brennstoffbenetzung vorliegende Oberflächenspannung als Rücklaufsperre wirkt, wenn das Filter aus dem Brennstoff austaucht.The invention relates to a filter arrangement for one Fuel tank, the filter for which is from a fuel pump sucked in fuel by the presence of fuel wetting surface tension as a backstop works when the filter emerges from the fuel.
Es hat sich gezeigt, dass in dieser Filteranordnung nach entleertem Brennstofftank bzw. Filterkammer bei neuer Füllung eine erhebliche Luftmenge verbleibt, da durch die bei Brennstoffbenetzung vorliegende Rücklaufsperrung diese auch für die in der Filterkammer enthaltene Luft wirkt.It has been shown that in this Filter arrangement after emptied fuel tank or filter chamber with new filling a considerable amount of air remains because of the presence of fuel wetting Return blocking this also for the air contained in the filter chamber acts.
Diese Luft gelangt ggf. in den Brennstoff, der von der Brennstoffpumpe abgesaugt wird und kann fehlerhaften Betrieb einer Brennkraftmaschine verursachen.This air may get into the fuel, which is sucked off by the fuel pump and can be faulty Cause operation of an internal combustion engine.
Aus JP 63/306271A und
Da diese Entlüftungsbohrung jedoch auch in umgekehrter Richtung wirkt, hebt sich die Sperrwirkung, die durch das benetzte Filtergewebe erreicht wird, auf. Es kann durch eine aufwändige Ventilanordnung versucht werden, diese Sperrwirkung zu sichern. Hierfür ist jedoch ein erheblicher Aufwand zu betreiben.However, since this vent hole is also in reverse Direction acts, the blocking effect is raised by the wetted Filter fabric is reached on. It can be done through an elaborate valve arrangement attempts are made to secure this blocking effect. For this, however a considerable effort to operate.
Hiervon ausgehend liegt der Erfindung die Aufgabe zu Grunde, Maßnahmen aufzufinden, mit denen die Entlüftung erreichbar wird, ohne die Sperrwirkung des Filters aufzuheben, wobei auf die Ventilanordnung verzichtet wird.The invention is based on this the task is based on measures find the vent with which can be reached without removing the blocking effect of the filter, whereby the valve arrangement is dispensed with.
Diese Aufgabe ist durch die im Patentanspruch genannten, kennzeichnenden Merkmale gelöst worden.This object is achieved in the claim mentioned, characteristic features have been solved.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and is described below.
Diese zeigt einen Schnitt durch eine Filteranordnung für einen Brennstofftank, wobei das Filter für den von einer Brennstoffpumpe angesaugten Brennstoff durch bei Brennstoffbenetzung vorliegende Oberflächenspannung als Rücklaufsperre wirkt, wenn das Filter aus dem Brennstoff austaucht.This shows a section through a Filter arrangement for a fuel tank, the filter for that from a fuel pump sucked in fuel due to surface tension during fuel wetting as a backstop works when the filter emerges from the fuel.
Diese Filteranordnung ist z.B. verwendbar

Mit der Filteranordnung nach der Erfindung liegt eine leicht anwendbare Ausführung vor, die auch für Entlüftungsbohrungen von Systemen Verwendung finden kann, die unter dem Brennstoffspiegel liegen und entlüftet werden müssen und bei denen eine Rücklaufsperre erforderlich ist, beispielsweise wenn die Brennstoffördereinheit mit Vorpumpe und Zwischenspeicher arbeitet.With the filter arrangement after the Invention is an easily applicable version, which is also for ventilation holes systems that are below the fuel level can be used and vented Need to become and where a backstop is required, for example if the fuel delivery unit works with backing pump and buffer.
