Abstract

A method of and a hydraulic circuit for distributing a liquid flow (Q) produced by a pump (2) uniformly to a plurality of hydraulic actuating means (9). The liquid flow from the pump is divided by means of a rotating multiblock distributor (4) into partial flows (Q1) which are each conducted to respective actuating means. Between each block (5) of the distributor and the associated actuating means is mounted a pressure control valve (7) by means of which the pressure (p1) of the partial flows (Q1) are adjusted to the same value which is higher than the working pressure (p2) of any actuating means (9) in order to maintain the pressure difference (ps-p1) constant over the individual blocks of the distributor irrespective of any variations in the working pressures of the actuating means. <IMAGE>
