摘要：
A pump device is operated according to a method for varying the duration of a supply stroke of a pump element, the supply stroke of which is actuated by a rotatably driven pump shaft (P) over a predetermined rotational position range of the pump shaft. In the method, the pump shaft (P) is rotatably driven by a drive shaft (A) and the angular speed of the pump shaft, at a constant angular speed of the drive shaft, is increased and decreased at least once during one revolution of the pump shaft.
