Abstract

A pressure reducer assembly (100) includes a pressure reducer body (110) defining at least one pressure reducer chamber (120) along a central axis (X-X′). The pressure reducer chamber (120) includes an inlet section (122) and an outlet section (124) fluidly coupled with the inlet section (122). The pressure reducer assembly (100) further includes a spring-operated hollow piston rod (121) having a center (X) along the central axis (X-X′), a cylindrical inner peripheral surface comprising an inner diameter (A), and a cylindrical outer peripheral surface comprising an outer diameter (B). A diaphragm (128) made of elastic material is adapted to be operatively coupled with the piston rod (121). The diaphragm (128) includes a central hole (150) having a center (Y) along a central axis (W-W′) and a diameter (C). The pressure reducer assembly (100) is characterized in that, in an unmounted state, the outer diameter (B) of the piston rod (121) is greater than the diameter (C) of the central hole (150) of the diaphragm (128), whereas in a mounted state, the outer diameter (B) of the piston rod (121) is the same as the diameter (C) of the central hole (150) of the diaphragm (128), and the diaphragm (128) is assembled over the piston rod (121) so that the central axis (X-X′) of the piston rod (121) coincides with the central axis (W-W′) of the diaphragm (128).
