Abstract

Un pistolet qui sert à exprimer synchroniquement et séparément dans l'espace deux ou plusieurs composants liquides et/ou pâteux, notamment des colles et des masses d'étanchéité, comprend un embout (1) qui se caractérise en ce qu'il contient une cavité façonnée de sorte qu'elle puisse recevoir au moins deux canaux concentriques et/ou symétriques et indépendamment échangeables d'amenée de matériau (2) et un support amovible (3) desdits canaux d'amenée de matériau (2) situé entre les canaux d'amenée de matériaux (2), ou un seul système amovible et échangeable (4) de canaux d'amenée de matériau qui comprend au moins deux canaux d'amenée de matériau (2) concentriques et/ou symétriques. Cette cavité a une ouverture plus grande du côté d'admission (5) que du côté de sortie (6) et les parois extérieures des canaux d'amenée de matériau (2) sont étroitement adaptées au support (3) et aux parois de ladite cavité.
