Abstract

The present invention relates to a valve comprising a body having a central conduit accommodating a sliding piston and a diaphragm connecting the body to the piston surrounding the piston. The diaphragm comprises an annular membrane for separating the central conduit from a pressurized fluid chamber. The body comprises an annular cradle, which extends radially between the central conduit and a peripheral annular ring of the diaphragm. The diaphragm takes an initial shape, where the annular membrane is distant from the annular cradle, when the piston is in a distal position and no overpressure occurs. The diaphragm is elastically deformed into stretched shapes, where the annular membrane comes in contact and mates with the annular cradle, under the effect of an overpressure occurring in the pressurized fluid chamber.
