Disclosed is a delivery unit () for an anode circuit () of a fuel cell system () for delivering a gaseous medium, in particular hydrogen, from an anode region () of a fuel cell (), said delivery unit () comprising at least one jet pump () and being at least indirectly fluidically connected to the outlet of the anode region () by means of at least one connection line () and being fluidically connected to the inlet of the anode region () by means of an additional connection line (). According to the invention, in addition to the jet pump (), the delivery unit () comprises a recirculation fan () and a metering valve () as other components, and the flow contours of the components () for the gaseous medium and/or the components () are at least almost entirely arranged in a common housing ().

A method for operating an axial piston machine of swashplate design, in which a swashplate is settable by means of an adjustment device, and in which a controlled variable of the axial piston machine is regulated by predetermining a manipulated variable. Under the assumption of a constant intended value of the controlled variable, a future profile of the controlled variable is ascertained using a model of the axial piston machine in which respective current values of at least one operating variable of the axial piston machine, which comprises the controlled variable, and a current value of the manipulated variable are taken into account. A value to be set for the manipulated variable is ascertained and set taking into account the future profile of the controlled variable.
