Abstract
The invention relates to a device for holding a storage tank by tensile stress inside an object, especially a movable object, e.g., a satellite, aircraft or motor vehicle, in which the storage tank is used for the storage of liquid or gaseous fluids, whose temperature exhibits a difference of at least 10.degree. C., in particular 30.degree. C., preferably 50.degree. C., to the outside temperature of the object. Here, the holding device contains a molded part made of a shape memory alloy (memory metal), which in the case of comparatively high mechanical stresses, especially during the take-off or lift-off of an aircraft or satellite or the driving of a motor vehicle, results in an increase of tensile stress, and in the case of comparatively small mechanical stresses, especially during flying of an aircraft or satellite or the standing of a motor vehicle, results in a reduction of tensile stress.
