Abstract

Die Erfindung bezieht sich auf ein Förderaggregat (30, 80), insbesondere für ein Hydraulikfluid zur Betätigung von Stellgliedern und/oder zur Begrenzung von Volumenströmen. Das Förderaggregat (30, 80) umfasst ein Gehäuse (12) mit mindestens zwei Pumpenzellen (32, 34). Die Pumpenzellen (32, 34) sind über ein Schaltventil (50, 70) schaltbar. Im Gehäuse (12) ist eine Antriebswelle (14) aufgenommen. Die mindestens zwei Pumpenzellen (32, 34) weisen voneinander verschiedene Fördervolumina auf.
