CONTROL DEVICE FOR ZERO-LEAK DIRECTIONAL CONTROL VALVES
Hydraulic system, distributor and bidirectional valve to activate the hydraulic actuators (3; 3a, 3b) of an operating machine; the hydraulic system (1) having: a first high-pressure oil delivery (4); an oil drain (8); a slide valve with a spool, which is axially sliding and is suited to control a hydraulic actuator (3); a second low-pressure oil delivery (6); an activation valve (15); and a bidirectional valve (21) with a first passage opening (22) that can be hydraulically connected, by the slide valve (9) to the first delivery (4) and a second passage opening (23) hydraulically connected to the actuator (3); wherein, the bidirectional valve has an inlet opening (24) that can be connected, by the activation valve (15) to the second delivery (6) and an outlet opening (25) that can be connected, by the spool (12) to the drain (8).
