Abstract

Mechanical control device assisted by fluid under pressure distributed to a jack with two chambers attached to the mechanism to be operated, in particular for vehicle steering control, comprising a control element that can be maneuvered at will and a mechanism for actuating said mechanism, between which is interposed a distributor of fluid under pressure, comprising a body and two mobile slides therein, which control the distribution of fluid under pressure, respectively, to the two chambers of the jack that normally put the exhaust, these slides being individually movable according to the direction of maneuver of the control member and against top-up recovery means that do not allow a relative sliding movement-body more than from a certain threshold of force exerted between the control and actuating elements mentioned in a sense or in the other, characterized in that said recovery means comprise, for each log, a chamber disposed between the latter (or the part that cooperates with it) and the body of the distributor, in which is applied, to determine said threshold of stress, a fluid under pressure independent of the variations of the pressure applied in the chamber of the cat fed by this slide.
