<p>Distribution device of the type comprising a body (30), a distribution slide valve (31) sliding inside the body and, when it moves, uncovering or blocking ducts (33) opening out, on the one hand, into the cavity and, on the other hand, to the outside of the body, these ducts being connected respectively to a source of hydraulic pressure (P), to a recovery reservoir (T) and to two inlets (A, B) of a hydraulic apparatus, means (42, 45) for moving the slide valve (31) translationally by an amplitude proportional to the angular value of rotation of the shaft (41) of a numerically controlled drive unit (40), characterised in that the said means (42, 45) also rotate the slide valve (31). <IMAGE></p> |
