The invention relates to a method and a circuit arrangement for controlling and regulating the supply of pressure medium to at least two hydraulic consumers, which are assigned in each case a directional valve for setting the flow and a setpoint signal source, by means of a pump with a variable displacement, which can be regulated by means of a displacement controller. The pump displacement is regulated according to the flow required by the setpoint signals. The individual load pressure of the consumers and of the consumer having the highest load pressure are determined. The directional valve of the highest loaded consumer is controlled to a valve-spool position y1, with y1=K.y1,max=const., which lies by a factor K, with 0<K<1, below the valve-spool position y1,max representing the maximum opening of the directional valve. This control of the directional valve of the highest loaded consumer has superposed on it at least one dynamic subcontroller which smoothes out pressure fluctuations via the residual opening of the directional valve remaining between the valve-spool positions y1 and y1,max.
