Tank for storing/transporting two separate liquids has rigid outer structure with two flexible inner containers of variable volume

摘要

The tank consists of a rigid outer structure (2) with mesh or solid walls holding two inner containers (20, 25) with supple, mobile walls that give them a volume that can vary between 0 and 100 per cent of that of the outer structure. Each container has an inlet (31, 33) and an outlet (32, 34), and fastenings (21, 22, 23, 24) for holding it to the rigid structure.
