Beschreibung
Zusammenfassung:	A main hydraulic circuit for controlling printing pressure of a printing machine is supplemented by an auxiliary high pressure generating circuit which becomes effective only after the pressure flow reversal in the main hydraulic circuit. The auxiliary circuit includes a pressure transformer or a hand-operated auxiliary pump connected via a back pressure valve to a hydraulic motor in the main circuit, and a second back pressure valve connected in series with a driving pump in the main circuit.
