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.
A valve/pressure regulator assembly for a pressurized gas bottle, comprising a body having a base portion having an axis for mounting on and coaxially with a neck portion of a bottle, the body supporting a shut-off valve, a pressure regulator, and a gas outlet fitting, all encompassed in a protecting hood mounted on and coaxially with the bottle, said hood having a closed upper part.
A valve/pressure regulator assembly for a pressurized gas bottle, comprising an integral body having a base portion for mounting on a gas bottle, the body defining a first gas circuit having an upstream portion in communication with the inner volume of the gas bottle and including a shut-off valve, and a downstream portion including a pressure regulator and in communication with a gas outlet, control means for manually adjusting the pressure regulator, and actuating means, movably supported on the body, for actuating the shut-off valve between an open position opening the upstream portion of the first gas circuit and a closed position closing the first gas circuit.
