Regulating device for an adjustable hydraulic pump with several consumers

A control device comprising and adjustable hydraulic pump, wherein said hydraulic pump is connected to a plurality of users, by respective delivery lines, each of said delivery lines including an adjustable proportioning throttle, controlled by said control device;

• a plurality of first control lines, each connected to a respective one of said delivery lines downstream of said respective proportioning throttle;
• a first pressure change device, which selects a highest pressure prevailing in said first control lines and supplies it to a delivery flow control valve;
• wherein said delivery flow control valve controls an adjusting pressure for an adjusting device to adjust a delivery volume of said hydraulic pump, based on a pressure difference between said highest pressure from said first pressure change device and a pressure from a second control line connected to said delivery lines upstream of said proportioning throttle;
• and a power control valve connected between said first control lines of a power-controlled group of users and a pressure medium tank, with pressure from said first control lines of said power-controlled group acting to open said power control valve, and said adjusting device acting, via a measuring spring arrangement, to close said power control valve;
• and wherein said first control lines of a non-power-controlled group of users are separated from said power control valve.
