Abstract: Described is a gas spring (200), comprising a guide (2), having an outer surface (212), a slider (1), defining with said guide (2) at least one chamber (11) containing pressurised gas, said slider (1) being slidably connected to said guide (2) in such a way as to have a maximum stroke, of expansion, wherein said guide (2) is partially extracted from said slider (1), and a maximum stroke, of compression, characterised in that it comprises a bushing (3), positioned between said slider (1) and said guide (2), comprising sealing means for the tightness of the chamber (11), and removably coupled and so as to move integrally with said slider (1) up to said maximum stroke, in such a way that, when said slider (1) slides with respect to said guide (2) beyond said maximum stroke, said bushing (3) decouples from said slider (1) so as to eliminate the seal of the chamber (11).
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
