ABSTRACT:
The fuel tank as disclosed is provided particularly for storage of aggressive fuel as they are used for and in control jets, attitude positioning systems in satellite and space vehicles. The fuel tank is of a spherical configuration and partitioned by a conical insert to obtain two spaces of different volumes. The small end of the cone faces the fuel outlet, opposite the driving gas inlet, and is constructed as a narrow mesh sieve. The fuel outlet is surrounded by a collection chamber likewise closed off by a narrow mesh sieve. The smaller one of the two chambers includes fuel lines which end in the corner space where the conical partition is affixed to the spherical tank and are closed likewise by sieves. The invention uses the strong surface tension forces of the fuel wetting the mesh to create a barrier against the passage of driving gas into the fuel line and outlet of the tank.
