ABSTRACT:
A nozzle for accelerating filling a container with gas up to a required gas pressure including a barrel having venturi openings in a side of said barrel and a sleeve that, in one position uncovers the tunnels and in another position, closes off the openings. In another version the nozzle further includes a pressure chamber, having a wall coupled to the sleeve. In a contracted position the sleeve is moved by the wall of the chamber to close off the tunnels. In another position of the wall where the chamber is in an expanded position the tunnels are so as to increase the rate of flow.
