Abstract
A safety device includes a ventilation channel to establish fluid communication between an Internal volume defined by a tank and the outside of the tank; a first safety member which is deformable and that keeps a safety piston in the closure position against an elastic force returning the safety piston to the safety position, structure for deforming the first safety member, and a second safety member intended, in a resting position, to hold the deformation structure in the resting position against an elastic force returning the deformation structure back to the deformation position when the second safety member experiences a temperature lower than a predetermined temperature and, in a working position, to release the elastic force for returning the deformation structure in the deformation position when the second safety member experiences a temperature higher than the predetermined temperature.
