Abstract (en)
[origin: FR2857704A1] The hydraulic distributor, consisting of a housing (2) with an inlet (P), a return port (T), two or more working ports (A, B), a slide valve (8) and a regulator (15), has two secondary non-return valves (40, 41) located in lengthwise channels (33, 34) upstream of the heads (31, 32) of its primary non-return valves (25, 26). The secondary non-return valves are connected via slots (50, 51) to the bore (4) containing the distributor's slide valve and are open during the hydraulic fluid escape phases in the slide valve section opposite the load pressure in the working ports.
