Abstract
A hydraulic arrangement includes a pump for delivering a hydraulic medium in a direction of a hydraulic working load. The pump includes an adjusting input for adjusting a delivery flow thereof. The arrangement also includes an accumulator unit hydraulically coupled on an output side to the pump and a charging valve unit hydraulically coupled on the output side of the pump between the pump and the accumulator unit. The charging valve unit is configured to function as a disconnectable hydraulic connection between the pump and the accumulator unit.
