Abstract
The invention relates to a method for adjusting supply pressure (p,) in a hydraulic system. The method comprises a feeder pump (,) for producing the supply pressure (p,), at least two hydraulic actuators (,), measuring means for measuring the pressure levels of the actuators (,), and a pressurized medium flow channel system. In the method, it is examined, in which actuators (,) the load pressure is caused by moving a load (positive work). From the pressure levels of the actuators (,) performing load-moving work, the highest is selected, and the supply pressure (p,) is adjusted on the basis of the selected pressure level.
