in the sorting chamber (34) and is adapted to adjust the introduction of gasoline
vapours into the sorting chamber (34) itself; a first pipe (39), which is obtained
in the wall (33) of the tubular body (30), puts the sorting chamber (34) into communication
with the plenum (25), and defines a first branch (28) of a recovery pipe (24); a second
pipe (40), which is obtained in the wall (33) of the tubular body (30) and defines
an initial portion of a second branch (29) of the recovery pipe (24); a first one-way
valve (27a) which is arranged in the sorting chamber (34) in correspondence of the
first pipe (39) and allows, through the first pipe (39), only a flow towards the plenum
(25); a second one-way valve (27b) which is arranged in the sorting chamber (34) in
