Abstract

Il dispositivo spruzzatore comprende una leva a grilletto (44) che aziona un pistone (40) mobile in un cilindro (20). Il pistone (40) comprende un ribassamento o scanalatura intermedia (42) che, cooperando con una valvola di compensazione (18), le permetta di chiudersi quando esso pistone (40) è sostanzialmente alla fine della corsa di aspirazione cioè in posizione di riposo.Nel corso del suo moto, il pistone (40) determina l'apertura della valvola di compensazione (18) (fig. 1).
