Abstract

L'invention concerne un pistolet de pulvérisation comportant un corps de pistolet (1), un manche (2) formé sur le corps (1), une admission d'alimentation (3) et une admission d'air (4) toutes les deux se trouvant sur le corps (1), une gâchette (5) se trouvant de manière correspondante sur le manche (2), et une aiguille (6) déclenchée par la gâchette. Le corps de pistolet (1) comporte un dispositif de réglage de débit (7) pour contrôler le déplacement de l'aiguille (6). Et le dispositif de réglage du débit (7) est arrangé au-dessus du manche (2) et à proximité de la gâchette (5). Par comparaison avec ces pistolets de pulvérisation qui ont le dispositif de réglage du débit sur leur extrémité arrière, le pistolet de la présente invention peut être plus facile à faire fonctionner, et la quantité de pulvérisation peut être réglée d'une seule main.
