The invention relates to a pressurized hydraulic fluid spool valve intended to be stacked against other similar spool valves, having a valve body (1) with a spool (4) adapted for sliding in a bore (5) into which open in the following order: a first intake recess (19) in a central position, two second recesses (21A, 21B) for connection to a hydraulic apparatus situated on each side of the preceding one; two third recesses (T.sub.1, T.sub.2) situated respectively beyond the second recesses, and two fourth recesses (22.sub.1, 22.sub.2) situated respectively beyond the third recesses.

Pressurized hydraulic fluid spool valve

The fluid distributor (D1) is intended to be stacked against similar distributors (D2); it comprises a distributor body (1) in which a slide-valve (2) may slide; this body comprises a transverse channel (8) extending from one bearing face (3) to another bearing face (4), this channel (8) being intended to be combined with at least one pressure selector (S); an upstream housing (9) is connected by a duct (10) to a zone where a working pressure is established, this upstream housing (9) being further connected laterally to said channel (8). The distributor body (1) comprises on its face (3), intended to be turned downstream, a downstream housing (16) communicating with the transverse channel (8), the upstream housing (9) of a downstream distributor (D1) coming, in a stack, opposite the downstream housing (16) of the adjacent upstream distributor (D2) so as to form the pressure selector (S).
