This device applies to the distribution of the charge air applied to the piston PS1 of the servomotor jack VR. It comprises: a pressure controller PR1 constituted by a bellows detector S1 and a switch V1, a cell ET and a slide valve distributor DC controlled by this cell and able to connect this jack with an air pressure reducer, the pressure controller PR1 opening one of the supply circuits of the cell at the moment at which it senses that the pressure in the enclosure to be protected reaches the calibrated pressure. <IMAGE>
