Abstract
A gear pump is described with at least two intermeshing gearwheels which are each rotationally fixedly connected to a shaft and separate a suction side from a delivery side. The shafts are mounted in a housing. One of the shafts can be brought into active connection with a drive unit and the other of the shafts can be brought into active connection with a pressure-control device which is to be driven by the drive unit via the two shafts. Furthermore, a drive device with the gear pump is proposed for setting an angle of attack of propeller blades of an adjustable-pitch propeller. In addition, an adjustable-pitch propeller having the drive device is described.
