Abstract

Die Offenbarung betrifft eine Pumpenanordnung umfassend eine Flügelzellenpum- pe (1) mit einem Rotor (2) und einem den Rotor (2) umgebenden Exzenterring (3), dessen Exzentrizität (e) in Bezug auf den Rotor (2) veränderbar ist, sowie Stellmittel (4) zur Veränderung der Exzentrizität (e) des Exzenterrings (3). Offenbarungsgemäß umfassen die Stellmittel (4) zwei vorzugsweise hydraulisch betätigbare Kolben (4.1, 4.2), die koaxial in Bezug auf eine Achse (5), an sich gegenüber liegenden Außenumfangsflächen des Exzenterrings (3) abgestützt sind, so dass deren Hübe eine lineare Verschiebung des Exzenterrings (3) ent- lang dieser Achse (5) bewirken.
