Abstract
Kraftstofffilter eines Kraftfahrzeug-Verbrennungsmotors mit einem Wasser-Sammelraum (2) für bei der Filtration aus dem Kraftstoff abgeschiedenes Wasser und einer von außerhalb des Filtergehäuses (1) betätigbaren, in den Wassersammelraum (2) eingreifenden Ablassschraube (3), wobei die Ablassschraube (3) einen außerhalb des Filtergehäuses (1) liegenden, ringförmigen Auffangkanal (7) mit einem nach außen führenden Abflussstutzen (8) aufweist, der bei geschlossener Ablassschraube (3) durch eine Dichtung von dem Wassersammelraum (2) getrennt ist und bei gelöster, noch nicht entfernter Ablassschraube (3) über einen, das Filtergehäuse (1) durchdringenden Auslasskanal (6) mit dem Wassersammelraum (2) kommuniziert, gekennzeichnet durch die Merkmale, – die Dichtung ist in einer Ausführung als axialer oder radialer Dichtring (9) in einer kreiszylindrischen Ausnehmung (11) des den Wassersammelraum (2) begrenzenden Filtergehäuses (1) gelagert, – der dichtende Bereich der Ablassschraube (3) liegt in der zylindrischen Ausnehmung (11) radial formschlüssig an der die Ausnehmung (11) bildenden Wand des Filtergehäuses (1) an, – in einem Übergangsbereich zwischen der Ausnehmung (11) und dem von dem Filtergehäuse (2) nach außerhalb der Ausnehmung (11) abstehenden Bereich der Ablassschraube (3) ist eine Sollbruch-Ringnut (12) für die Möglichkeit eines Abscherens des außerhalb der Ausnehmung (11) liegenden Bereiche der Ablassschraube (3) unter einer im Falle eines Fahrzeugcrashes auftretenden Scherkraft vorgesehen.A fuel filter of a motor vehicle internal combustion engine having a water collecting space (2) for water separated from the fuel during filtration and an outlet screw (3) which can be actuated from outside the filter housing (1) and into the water collecting space (2), the drain plug (3 ) has an outwardly of the filter housing (1), annular collecting channel (7) with an outwardly leading outflow nozzle (8) which is closed with a closed drain plug (3) by a seal from the water collection chamber (2) and dissolved, not yet remote drain plug (3) via a, the filter housing (1) penetrating outlet channel (6) communicates with the water collecting space (2), characterized by the features, - the seal is in an embodiment as an axial or radial sealing ring (9) in a circular cylindrical recess (11) of the water collecting chamber (2) limiting the filter housing (1) stored, - the sealing region of Ablasssch (3) is in the cylindrical recess (11) radially positive fit on the recess (11) forming wall of the filter housing (1), - in a transition region between the recess (11) and the filter housing (2) to the outside the recess (11) projecting portion of the drain plug (3) is a predetermined breaking annular groove (12) for the possibility of shearing the outside of the recess (11) lying areas of the drain plug (3) provided under a shearing force occurring in the event of a vehicle crash.
Description
Die Erfindung betrifft ein Kraftstofffilter eines Kraftfahrzeug-Verbrennungsmotors nach dem Oberbegriff des Patentanspruchs.The invention relates to a fuel filter of a motor vehicle internal combustion engine according to the preamble of the claim.

Die Erfindung beschäftigt sich daher mit dem Problem, die Ablassschraube derart innerhalb des Filtergehäuses zu dichten, dass ein Lösen der Dichtung im Falle eines Fahrzeugcrashes, in dem erhebliche Scherkräfte auf die Ablassschraube einwirken, mit einer möglichst hohen Sicherheit vermieden werden kann.The invention therefore deals with the problem of sealing the drain plug within the filter housing so that a release of the seal in the event of a vehicle crash, in which considerable shear forces acting on the drain plug can be avoided with the highest possible safety.
Gelöst wird dieses Problem durch eine Ausführung eines gattungsgemäßen Kraftstofffilters mit einer Dichtung der Ablassschraube innerhalb des Filtergehäuses nach dem kennzeichnenden Merkmal des Patentanspruchs 1.This problem is solved by an embodiment of a generic fuel filter with a seal of the drain plug within the filter housing according to the characterizing feature of patent claim 1.
Die Erfindung beruht auf dem allgemeinen Gedanken, die Dichtung zwischen Ablassschraube und Filtergehäuse in einen innerhalb des Filtergehäuses geschützten Raum zu legen und gleichzeitig denjenigen Bereich der Ablassschraube, der die außerhalb des Filtergehäuses im Falle eines Fahrzeugcrashes auf insbesondere Abscherung beansprucht werden kann, durch eine Sollbruchstelle von dem dichtenden Bereich der Ablassschraube zu trennen. Auf diese Weise kann der außerhalb des Filtergehäuses liegende Bereich der Ablassschraube im Falle eines Fahrzeugcrashes sich ohne eine Beeinträchtigung der Dichtwirkung von dem die Dichtung aufnehmenden Teil der Ablassschraube über die Sollbruchstelle lösen. Besonders vorteilhaft ist das Vorsehen einer Radialdichtung in dem geschützten Filtergehäusebereich. Denn bei einer Radialdichtung bleibt die Dichtfunktion auch noch bei einer leichten gegenseitigen Verformung der als Widerlager für die Dichtung dienenden Gegenflächen vollständig erhalten.The invention is based on the general idea to place the seal between the drain plug and filter housing in a protected inside the filter housing space and at the same time that portion of the drain plug, which can be claimed outside the filter housing in the event of a vehicle crash on particular shearing, by a predetermined breaking point of to separate the sealing area of the drain plug. In this way, the region of the drain plug lying outside the filter housing in the event of a vehicle crash can disengage from the seal receiving part of the drain plug via the predetermined breaking point without adversely affecting the sealing action. Particularly advantageous is the provision of a radial seal in the protected filter housing area. Because with a radial seal, the sealing function is still completely preserved even with a slight mutual deformation of serving as an abutment for the seal mating surfaces.
