ABSTRACT:
The present invention relates to a pressurized suit (10) fitted with elastic gloves (1) and co-operating with respective devices (20) for reducing the pressure (P.sub.M) inside each glove relative to the pressure (P.sub.C) inside the suit (10) in order to increase manual dexterity of the astronaut. Each device includes an inflatable elastic cuff (30) which is disposed between the glove (1) and the remainder of the suit (10) together with means for pressurizing the cuff (30), said means being constituted by a micro-pump (40) which sucks air from inside the glove (1) and delivers it into the deformable chamber (31) of the cuff (30), together with a control valve (50a) for controlling the pressure (P.sub.j) inside the cuff (30). The invention is applicable to extra-vehicular activity (EVA).
