Abstract

Improvements in the step-by-step servo mechanisms, of the jack type, which have, on the one hand, a movable motor element in a casing which it separates into two chambers and provided with a plurality of receiving holes and, on the other hand, a distributor arranged to be connected with high and low pressure and to supply said receiving holes, characterized in that the distributor is fixed and has a number of supply or emitting holes at least equal to three but independent of the number of holes receivers, and capable, by permutation, of being connected successively, in pairs, respectively with low pressure and with high pressure, such being the distance between the receiving holes and their length, on the one hand, and the distance between the emitting holes and its length, on the other hand, that, by step-by-step displacement, in one sense, of the motor element, on the one hand, can be carried each time by at least a receiving hole between the two emitting holes of a pair in such a position that it does not communicate with either one or the other of these holes, but that any displacement in one direction or the other of the motor element puts into communication at least less one receiving hole, respectively, with the one or the other of the two emitting holes and, on the other hand, that the one of the emitting holes of a next pair to be fed leads to a receiving hole.
