Abstract: A method for manufacturing a hollow body, typically a tank, from a plastic material. The method includes molding a preform into shells in a molding tool; joining an insert to an inner surface of a shell of said shells, the insert defining a sub volume within the hollow body to be made; joining together the shells to form the hollow body by closing the molding tool and applying a main pressure to a main volume enclosed by the shells. It is proposed to apply a sub pressure to the sub volume while applying the main pressure to the main volume, such that a pressure difference between the main volume and the sub volume is bigger than 0.20 bar (P1??P2?>0.20 bar) and smaller than 3.00 bar (P1??P2?<3.00 bar).

Abstract: A filling nozzle of a fuel tank including a receiving pipe and a liquid-vapor separator, includes a hollow body communicating with an intake pipe for a stream of vapors from the fuel tank, an emptying pipe flowing into the receiving pipe, and a vapor outlet pipe. The hollow body includes a separation mechanism extracting droplets and including at least one wall movable between first and second configurations. In the first configuration the movable wall forms, together with walls of the hollow body, a maze in which stream of vapors passing from the intake pipe towards the outlet pipe is forced to circulate. In the second configuration the movable wall allows the stream of vapors to pass from the intake pipe to the outlet pipe following a path that avoids all or part of the path travelled by the vapors when the movable walls are in the first configuration.
