Cryogenic Fuel Tank And Use Thereof In A Motor Vehicle

Abstract

A cryogenic fluid tank comprising an outer envelope ( 2 ) and an inner envelope ( 1 ), wherein the space between said envelopes is occupied by a multilayered insulation structure ( 3 ) wherein the inner envelope ( 1 ) is supported on a point of articulation (A) formed by a support structure ( 6 ) coupled to the outer envelope ( 2 ) and extending into the latter, wherein the point of articulation is located above the center of gravity (G) of the inner envelope. Applications: cryogenic fuel tanks in motor vehicles.

1 - 8 . (canceled)  
   
   
       9 . A cryogenic fluid tank, comprising an outer envelope and an inner envelope, the interspace between the envelopes being occupied by a multilayer insulating structure, wherein the inner envelope is supported on a pivot point (A) formed by a support structure secured to the outer envelope and extending inside the latter, the pivot point being situated above the center of gravity (G) of the inner envelope.  
   
   
       10 . The tank of  claim 9 , wherein the support structure extends inside a hollow volume of the inner envelope.  
   
   
       11 . The tank of  claim 10 , wherein it has lines for the transfer of fluids and/or electrical signals communicating with the inside of the inner envelope and extending outwards into the support structure.  
   
   
       12 . The tank of  claim 9 , wherein the inner envelope has a generally cylindrical configuration with a longitudinal axis.  
   
   
       13 . The tank of  claim 12 , wherein the support structure is orthogonal to the longitudinal axis.  
   
   
       14 . The tank of  claim 10 , wherein the hollow volume is formed by a bell-shaped structure extending transversely centrally inside the inner envelope.  
   
   
       15 . The tank of  claim 9 , wherein the pivot point is formed by a ball joint positioned between the walls of the hollow volume and the support structure.  
   
   
       16 . A use of the tank of  claim 9  in a motor vehicle.
