Abstract (en)
[origin: WO2014053764A1] The invention relates to a residual pressure valve device comprising a shut-off member (1) that is able to move in the body (9) relative to a seat (2), a return member (5) that urges the shut-off member (1) by default towards the seat (2), the shut-off member (1) comprising an internal duct (6) having a first end in communication with the gas inlet (3) and a second end that leads, via a calibrated orifice (8), into a control chamber (7) that is closed by the shut-off member (1) such that, when the gas pressure in the control chamber (7) reaches a predetermined threshold, this pressure causes the shut-off member (1) to move away from the seat (2), the body of the shut-off member (1) comprising a first portion (11) that forms a male element which is able to move in translation in a female passage of the body (9) with a predetermined fit forming a restriction ensuring partial and progressive opening of the passage for the gas between the inlet (3) and the outlet (4).
