SYSTEM FOR FILLING A TANK

摘要

System for filling a tank comprising a head (12) and a fill pipe extending between the head and the tank, in which: the pipe head comprises a chamber (32) with an inlet opening (16) that connects to the atmosphere and an outlet opening (18) that connects to the fill pipe and a stopper (20) to close the access to the fill pipe, the stopper being movable between an open position, in which the access to the fill pipe is open, and a closed position, in which the access to the fill pipe is closed, the inlet and outlet openings of the head being sized and arranged so as to allow introduction of a filling nozzle into the fill pipe through the pipe head when the stopper is in its open position; the fill pipe comprises or is preceded by a local restriction (40) designed so that the cross section of the passage for the nozzle is substantially reduced to the outer diameter of the nozzle; and a degassing connection links the fill pipe and the fill head outside of the outlet opening of the latter head.
