The tap/pressure regulator assembly, advantageously housed in a streamlined cowl forming a bottle-handling bonnet (C), comprises a body (1) intended to be mounted on a gas bottle and defining, on the inside, a gas utilization circuit, going to an outlet (3) via an isolating valve actuated by a lever (5) and via an adjustable pressure regulator (4, 25), and an independent filling circuit going from a filling fitting (6). The body (1) also carries high-pressure and low-pressure pressure gauges (8). Application especially to welding gases. FIG. 2 to be reproduced.

The pressure reducer body includes oppositely disposed bores for mounting inlet and outlet connecting devices, and the outer end of another bore defining a high pressure chamber in which the regulating valve is mounted, is adapted to receive a connecting device for a high pressure manometer defining a rest for a spring of a regulating valve which includes an annular truncated lining in which is force fittingly engaged a connecting rod between the regulating valve and the piston bounding the low pressure chamber. Applications to various pressure reducer arrangements for industrial use.
