In an hydraulic distributor (2) having one or more operative portions having slides (7A,7B) adjusting the flow rate to the utilization and the oil backpressure at the inlet and local pressure compensators (8A,8B) controlling the pressure drop at the ends of recesses adjusting the slide flow rate, the slide, according to its position, opens a connection (20) between a channel receiving the oil from the pump (1) and the channel delivering oil to the actuator (3A,3B) through a shutter having a spring (22) adjusted so that the pressure for opening the shutter, is greater than "LS ”P" set by the LS regulator of the pump. Said connection is parallel to the oil path through the adjusting recesses of the slide flow rate and local compensator.
