A control device for an adjustable hydraulic pump (,), wherein the hydraulic pump is connected to a plurality of users, by delivery lines (,). A first control line (,), is connected to each of the delivery lines downstream of a respective proportioning throttle (,). A first pressure change device (,) selects a highest pressure prevailing in the first control lines and supplies it to a delivery flow control valve (,), which controls an adjusting pressure for an adjusting device (,) for the hydraulic pump, based on a pressure difference between the highest pressure from the first pressure change device and a pressure from a second control line (,) connected to the output of the pump. A power control valve (,) is connected between the first control lines of a power-controlled group of users and a pressure medium tank (,), with pressure from the first control lines acting to open the power control valve, and the adjusting device acting, via a measuring spring arrangement (,), to close the power control valve. The first control lines of a non-power-controlled group of users are separated from the power control valve.
