ABSTRACT:
A control is proposed for dividing the output flow in hydraulic systems made available by at least one pump to a plurality of users according to the load pressure-independent principle in case of output flow undersupply of the users, wherein a compensator is connected downstream of each control slide valve provided with a predeterminable control cross section, with the compensator including a piston and actuating element and each user connected downstream of the compensator receiving a predeterminable portion of the output flow as a function of the degree of undersupply by the pistons of the compensators, with the piston being acted upon by different forces which bring about different opening pressures.
