Abstract

Cryogenic tank for storing liquefied fluid, having an inner shell delimiting a storage volume for liquefied fluid and an outer shell arranged in a spaced manner around the inner shell, the space between said inner and outer shells having a thermal insulation, a first mechanical connection having a first support wall of truncated cone shape whose larger-diameter end is rigidly connected to the outer shell and whose smaller-diameter end is connected to the inner shell, wherein a second mechanical connection has a second support wall of truncated cone shape whose larger-diameter end is rigidly connected to the outer shell and whose smaller-diameter end is connected to the inner shell.

Abstract

Vehicle for delivering inflammable fluid comprising a tractor unit and a tank mounted on a support, the vehicle including a fluid circuit connected to the tank that includes a set of pneumatic valves. The vehicle includes an electrical circuit having at least one electrical component and an electricity source connected to the electrical circuit via at least one port for connecting to a connection interface. A cover moves between a first position blocking access to the connection port(s) to prevent the electrical connection between the electricity source and the electrical circuit and a second position not blocking access to the connection port(s) to enable the electrical connection between the electricity source and the electrical circuit. The vehicle includes a switch connected to the fluid circuit switchable between a first state enabling the operation of the set of pneumatic valves to allow filling or draining and a second state preventing the operation of the set of pneumatic valves to prevent filling or draining. In its first position, the movable cover switches the switch or allows it to is be switched to its first state. When the movable cover is in its second position, the switch is automatically switched to its second state.
