Abstract
The disclosure relates to a valve comprising a body defining at least an admission duct and an outlet duct for a fluid and receiving a valve member that is movable by means of an actuator member fastened to the body to move between a closed position closing the outlet duct and an open position leaving it open, the valve member having a central portion secured to a central portion of a substantially plane diaphragm that has a peripheral portion associated in leaktight manner with a support element secured to the body in such a manner as to co-operate with the support element to define a chamber, the valve member and the diaphragm being pierced by an opening providing permanent communication between the chamber and the outlet duct, the diaphragm being elastically deformable and being dimensioned to urge the valve member into its closed position.
