Abstract

The invention relates to a release valve (100), installable on a container intended to contain a pressurized fluid and capable of maintaining a pressure difference between a first environment (9) and a second environment (90), comprising a housing (8), a first thrust means (3), a closure element (5), and a slider (2), wherein said housing (8) contains at least said slider (2) and said first thrust means (3), wherein said slider (2) comprises a first surface (25) facing the first environment (9), and a second surface (26), facing the second environment (90), and having an area greater than said first surface (25), wherein said closure element (5) is interposed between said second environment (90) and said slider (2), and wherein said first thrust means (3) is positioned between said slider (2) and said housing (8), so as to obtain at least one closed contact profile between said closure element (5) and said second surface (26), wherein said release valve (100) is characterized in that said fluid exerts on said second surface (26) a pressing force greater than the pressing force exerted on said first surface (25), and in that said first (25) and second (26) surfaces are arranged in such a way that, if the pressure difference between said first environment (9) and said second environment (90) remains below a predetermined value, said first thrust means (3) realizes said closed contact profile between said closure element (5) and said slider (2).
