Title
(DE) Wasserabscheider mit durch Schwimmerventil gesichertem Wasserüberlauf
Abstract
(DE)

Die Erfindung betrifft einen Wasserabscheider (10), insbesondere in Form eines Kraftstofffilters für ein Kraftfahrzeug. Der Wasserabscheider (10) weist einen Wassersammelraum (30) auf. Der Wassersammelraum (30) ist mit einem Überlaufventil (38) gegenüber einer Ableitungs-Durchgangsausnehmung (34) verschlossen. Das Überlaufventil (38) weist einen Schwimmer (44) auf, der leichter als Wasser, aber schwerer als Kraftstoff, insbesondere schwerer als Dieselkraftstoff ist. Der Schwimmer (44) schwimmt bei im Wassersammelraum (30) angestautem Wasser auf und gibt die mit dem Überlaufventil (38) fluidisch verbundene Ableitungs-Durchgangsausnehmung (34) frei, über die das angestaute Wasser abfließen kann. Kraftstoff öffnet demgegenüber das Überlaufventil (38) nicht, so dass nur im Falle einer Wasserstauung eine Ableitung über die Ableitungs-Durchgangsausnehmung (34) aus dem Wasserabscheider (10) erfolgt, wodurch der Wirkungsgrad des Wasserabscheiders (10) stark erhöht wird. Die Ableitungs-Durchgangsausnehmung (34) ist bevorzugt fluidisch mit einem Kraftstofftank des Kraftfahrzeugs verbunden. Zum regulären Wasseraustrag aus dem Wassersammelraum (30) ist dieser vorzugsweise mit einer Wasseraustragseinrichtung verbunden.
