STORAGE OF PRESSURISED FLUIDS

摘要

A storage apparatus for storing a pressurised fluid comprises an outer vessel (2) and a plurality of separately sealed inner vessels (4). Means are provided for communication with the interiors of the inner vessels and of the outer vessel respectively (6,18,12). Also disclosed is a valve (12) for selectively allowing the passage of a fluid. The valve comprises a membrane (14) which is impermeable, within a predetermined temperature range, to the fluid to be stored. It also comprises heating means (16) for raising the temperature of the membrane above said temperature range, thereby allowing the fluid to diffuse through the membrane.
