Afin de pouvoir alimenter automatiquement le gazogene en charges de combustible, tel que le bois, en quantite suffisante, lorsque de grandes quantites de gaz sont exigees, le transporteur (2) comprend un piston de charge (8) qui est dispose dans un cylindre (7) et qui execute un mouvement de va-et-vient devant l'ouverture de sortie de la tremie (1). Le bord du piston qui passe devant cette ouverture de sortie est coupant.
