Title: CYLINDER OF PRESSURISED FLUID
Abstract:
The invention relates to a cylinder of pressurised fluid, in particular of pressurised gas, which includes a valve (7) containing a fluid circuit (17) comprising at least one isolation valve (47), the cylinder (6) being provided with a cap (1) for protecting the valve (7) including a rigid structure defining a protective space around the valve (7), the cylinder (6) including a pressure-indicating device including at least one pressure-sensitive piston (26) which is inside the cylinder (6) and is movable, relative to the body of the valve (7) and according to the pressure level inside the cylinder (6), between at least one first retracted position and a second deployed position, the pressure-indicating device including at least one movable storage medium (28) intended for mechanically engaging with the piston (26), the storage medium (28) being movable between at least two separate positions or states in order to symbolise at least two pressure levels, respectively, according to the position of the piston (26), characterised in that the cap (1) includes at least one opening (31) forming a window for viewing the position or the state of the storage medium (28).
