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.
