Abstract
(DE)
Die Offenbarung betrifft eine Verdrängerpumpe (10), insbesondere eine Flügelzellenpumpe zur Förderung eines Fluides für einen Verbraucher (6) eines Lenksystems (1), wobei der Rotor (24), der Kurvenring (20), die gehäuseseitige Steuerplatte (32) und die deckelseitige Steuerplatte (34) in zusammengesetztem Zustand ein Läuferpaket (35) bilden, und wobei die gehäuseseitige Steuerplatte (32) in axialer Richtung benachbart zu einer Gehäusestirnfläche (36) und die deckelseitige Steuerplatte (34) in axialer Richtung benachbart zu einer Deckelstirnfläche (38) angeordnet sind, wobei das Läuferpaket (35) zwischen der Gehäusestirnfläche (36) und der Deckelstirnfläche (38) in axialer Richtung bewegbar ist. Die Offenbarung betrifft des Weiteren ein Verfahren zum Betreiben einer Verdrängerpumpe (10) sowie ein Lenksystem (1).
(EN)
The disclosure relates to a positive-displacement pump (10), in particular a vane-type pump for the delivery of a fluid for a consumer (6) of a steering system (1), wherein the rotor (24), the cam ring (20), the housing-side control plate (32) and the cover-side control plate (34) form, in an assembled state, a rotor assembly (35), and wherein the housing-side control plate (32) is arranged adjacent to a housing face surface (36) in an axial direction and the cover-side control plate (34) is arranged adjacent to a cover face surface (38) in the axial direction, wherein the rotor assembly (35) is movable in the axial direction between the housing face surface (36) and the cover face surface (38). The disclosure also relates to a method for operating a positive-displacement pump (10), and to a steering system (1).
