  "textContent": "The valve (20) comprises a cup (3) closed by a cover (2) having a through opening (6). The cup (3) has a circular cross-section and comprises two vent holes (7a, 7b) diametrically opposed on its circumferential wall. An elastic flapper (21), having three vertices arranged in a triangle and connected two by two by a respective circular arc - preferably in the shape of a REULEAUX triangle - is compressed between the bottom (5) of the cup (3) and the cover (2). In this way, the flapper (21) closes the opening (6). When the fluid pressure present at the level of the opening (6) is sufficient, the fluid further compresses the flapper (21) and finds a path between the flapper (21) and the cover (2) to then escape through the vent holes (7a, 7b). The valve (20) is adapted to be used on an electrochemical generator in which case the cover (2) can serve to close its housing (15).",
