Abstract
An assembly comprising an intermediate volume of medium-pressure gas (8) in a transportable housing (3) which is advantageously combined with a user apparatus (4) and selectively connectable to a high-pressure gas supply (1) by coupling it to a filling unit (2) via a quick connection system (15, 16). The assembly is particularly useful in portable welding apparatuses.
Claims15
A gas supply device for supplying gas under pressure to a portable user apparatus, comprising, in a first portable casing, a gas container mounted in said first portable casing, a gas outlet circuit for fluidly connecting the gas container to the user apparatus, and a gas inlet circuit for connecting the gas container to a source of gas under pressure, the gas outlet circuit including a first pressure reducer and a first flow control valve, said first portable casing defining a support base on which said user apparatus is mounted when in use, and releasable connecting means independent of said gas outlet circuit for mechanically interconnecting together the first casing and the user apparatus to form a unitary transportable operating assembly.
A gas supply equipment for supplying gas under pressure to a portable user apparatus comprising:
- a filling station including an outlet head in fluid flow communication with a source of gas under pressure;
- a transportable gas reserve assembly including a gas container, a gas inlet circuit having a filling head for quick coupling to the outlet head of the filling station, a gas outlet circuit including an end fitting for fluid flow connection to the user apparatus and a flow control valve, said gas reserve assembly defining a support base on which said user apparatus is mounted when in use, and releasable mechanical connecting means independent of said gas outlet circuit for interconnecting together the gas reserve assembly and the user apparatus.
