Abstract:
1. A controlled pneumatic valve, intended for remote control of the inflation and deflation of a capacity, the valve comprising: a membrane structure, maintained between a valve body which has openings and a cover, said membrane structure and said cover defining on one hand a control chamber, and said membrane structure and said body defining on the other hand an outflow chamber, said membrane structure being movable between a first position permitting fluid communication between said outflow chamber and the capacity while at the same time isolating said outflow chamber from said control chamber, and a second position permitting fluid communication between said control chamber and the capacity, while at the same time closing the outflow chamber; at least one lever which rests on a stationary part of said cover or of said body for reversing the direction of the force provided by said membrane structure during application of a negative pressure in said control chamber; and a flap coupled to said lever, said lever ensuring the opening of said flap under the action of a positive control pressure as well as a negative control pressure in said control chamber with respect to the ambient pressure.
