<p>A pressurized medium circuit for controlling a motor irrespective of the load, comprising: a pressure line (P, MP), a tank line (T, MT), and a valve (3) whose internal flow resistance can be changed in a controlled manner and which is placed in the pressure line (P, MP), wherein the valve (3) is arranged to control the volume flow of the medium to be supplied to the motor (M). The pressurized medium circuit (1) also comprises a pressure compensator (4) which is placed in a return line (T, MT) and which is arranged to equalize the pressure difference effective over the valve (3) in such a way that the internal flow resistance of the pressure compensator (4) is increased when the pressure difference effective over the valve (3) tends to increase, and that the internal flow resistance of the pressure compensator (4) decreases when the pressure difference effective over the valve (3) tends to decrease.</p> |
