    摘要: A pressure regulator valve including a safety valve, the pressure regulator valve (10) comprising a body (1) enclosing a gas passage (2), a regulator piston (3) mobile with respect to a piston seat (4) between a first and upstream position wherein a first end (13) of the regulator piston (3) closes the gas passage (2) and a second position wherein said first end (13) of the regulator piston (3) opens the gas passage (2), the regulator piston (3) comprising a internal gas conduit (6) comprising an upstream end receiving gas flowing from the open piston seat (4) and a downstream end connected to a working chamber (7) closed by a second end of the regulator piston (3), the pressure regulator valve (10) comprising a return spring (5) generating a effort on the regulator piston (3) which is opposite to the effort generated by the gas pressure in the working chamber (7) on the regulator piston (3), the safety valve comprising an obturator (8) mobile on the regulator piston (3) between a first position closing a gas exit (16, 9) and second position opening the gas exit (26, 9), the obturator (8) being urged toward its first position by the return spring (5), characterized in that, the return spring (5) and the obturator (8) are located in a cavity of the body (1) and extend in the longitudinal direction on a distance included between 90% to 130% of the distance (D) from the second end of the regulator piston (3) to the piston seat (4).
