The body 1 has, at one end, a downstream coupling 4 intended to be connected to a use member, and it has, at its other end, a base 10 pierced with an inflation orifice 19. Inside the body 1 there is arranged a movable disc 8 fixed to a valve 5 which can be applied to a sealing seat 3 surrounding the orifice of the coupling 4. The disc 8 limits, with the bore 9 of the body 1 and the base 10, a small capacity 16 inside which is housed a pilot valve 18 interacting with the orifice 19. The opening of the pilot valve 18 under the action of the electromagnet 20 causes the pressure in the small capacity 16 to fall, which forces the valve 5 to move away from the seat 3 under the action of the pressure of the fluid. The device permits the creation of a powerful and rapid thrust exerted on objects, for example loads carried beneath aeroplanes, or alternatively protective panels. <IMAGE> |
