ABSTRACT:
The described injection system includes: a pneumatic system operating with hydrogen or helium and formed of one or more two-stage or multi-stage propulsion systems provided with special control or cutoff valves, the relative feeding circuits, and one or more decompression chambers, a cryogenic device formed of a Dewar flask containing liquid helium, a circuit for transferring and recovering the cooling fluid, and one or more conventional (in situ) or alternative cryostats provided each with one or more launching barrels in which the cryogenic pellets are solidified; a vacuum system comprising electrovalves, electropneumatic valves, rotating and turbomolecular pumps, and an equipment set for the automatic remote control of the whole system and for collecting and supplying diagnostic data to the central processing unit.
