Zusammenfassung:The invention relates to a method for operating a device (1) having a hydraulic pressure source (2) and a controllable flow control valve (3). A hydraulic pressure (p_sys) of the pressure source (2) is applied to the flow control valve (3). An actuating pressure (p_16) for a hydraulically actuatable switching element (9) is additionally set in the region of the flow control valve (3). The actuating pressure (p_16) lies downstream of the flow control valve (3) in the region of a piston chamber (16) of the switching element (9), in which a piston (17) is arranged so as to be longitudinally displaceable between two end positions. A pilot control of the flow control valve (3) occurs as a function of a hydraulic fluid volume flow, which is to be guided through the flow control valve (3), in order to generate a predetermined time progression of the actuating pressure (p_16) in the piston chamber (16) of the switching element (9).
