Abstract

Tank with a double wall which is held permanently or intermittently under vacuum from a source (8) connected to a space between its outer wall (1) and the inner wall (2). The space is connected to the inside of the tank by a nonreturn valve and contains an insulating filling (4), in which are cavities connected together and exposed to the vacuum. The cavities are formed by pores of an insulating foam filling or a relocated between the insulating filling (4) and air extracting plates covering the outer surface of the inner wall (2). Alternatively, the cavities are located between corrugated plates covering the inner wall (2) of the tank and outer surface of the inner wall.
