Abstract
Improvements in sealing devices with assisted actuation, characterized by the fact that a primary pressure chamber is established, connected by an orifice to a pressurized fluid inlet; a deformable membrane constituting at least partially a wall of the primary pressure chamber; a shaft held at a point in the membrane and on which a movable clapper valve is mounted between a first seat through a chamber wall and a second seat that opens into a drain hole: a compression chamber attached, on the one hand, to a fluid outlet channel to a receiving apparatus and, on the other hand, to the primary pressure chamber through the first seat or to the drain hole through the second seat; a reaction chamber one of whose walls is constituted at least partially by the membrane and which is located on the side of the membrane, opposite the primary pressure chamber; a reaction channel that puts the reaction chamber in communication with the compression chamber; a push rod operated by hand from outside the apparatus and penetrating through an opening in the reaction chamber so that it can rest on the end of the shaft fixed to the membrane and lift the movable flap valve from its first seat .
