Abstract

Eine Pumpe zum Fördern eines Fluids, insbesondere Flügelzellenpumpe, mit einer in einem Gehäuse (2) untergebrachten Fördereinrichtung, einem stirnseitigen Gehäusedeckel (3) und gegebenenfalls einem sich auf der dem Gehäusedeckel (3) gegenüberliegenden Seite an das Gehäuse (2) anschließenden Lagerflansch (4), wobei zwischen dem Gehäuse (2) und dem Gehäusedeckel (3) und gegebenenfalls zwischen dem Gehäuse (2) und dem Lagerflansch (4) eine Dichtung (5, 6) angeordnet und die Dichtung (5, 6) in eine im Gehäusedeckel (3) und gegebenenfalls im Lagerflansch (4) und/oder in der jeweiligen Stirnfläche (7) des Gehäuses (2) ausgebildete Nut (8, 9) eingesetzt ist und wobei sich zwischen Druckseite (11) und Saugseite (12) ein Leckagepfad (13) für das Fluid erstreckt, ist zur sicheren Abführung des druckseitigen Lecköls bei Reduzierung der konstruktiven bzw. fertigungstechnischen Maßnahmen dadurch gekennzeichnet, daß der Leckagepfad (13) auf der Dichtungsinnenseite (14) - Medienseite - zumindest bereichsweise parallel zu der Dichtung (5, 6) verläuft.
