A nozzle (20) is used in a hand held dispenser of viscous fluid including caulking, sealant or adhesive. The nozzle (20) has an elongated body that extends along a longitudinal axis, defining a fluid path extending between a dispensing end (21) and a base (32). The base includes a coupling (30) to secure the nozzle (20) to a dispensing device or to a container (10) of the viscous fluid. The nozzle (20) includes a variable flow valve (26) that operates through a range of positions, between a fully closed position and a fully open position. The valve (26) operates within a housing (27) that extends across the longitudinal axis of the body. A second coupling (28) connects the valve (26) to a hand control on the dispenser. Preferably, the valve (26) rotates between the closed and open positions. The nozzle (20) is also included in a dispensing gun. The dispensing gun includes a hand activated control on the gun handle. The control operates the valve (26) between the closed and open positions and co-acts to urge the fluid contents of the dispensing gun to flow through the nozzle (20). A kit for a nozzle assembly in a hand held dispenser includes the nozzle (20) and a replaceable nozzle tip (23). The kit may also include one or more interchangeable nozzle tips (23), a replaceable end cap (305), and a cleaning tool (100) for the nozzle.

L'invention concerne une buse (20) de distributeur manuel de fluide visqueux, qui comprend du calfeutre, un agent d'étanchéité ou un adhésif. La buse (20) comporte un corps allongé qui s'étend le long d'un axe longitudinal, définissant un trajet de fluide entre une extrémité de distribution (21) et une base (32). La base comprend un couplage (30) visant à fixer la buse (20) à un dispositif de distribution ou un contenant (10) qui contient le fluide. La buse (20) comprend une soupape à débit variable (26) à plusieurs positions, entre une position fermée et une position ouverte. La soupape (26) se trouve dans un logement (27) qui s'étend en travers de l'axe longitudinal du corps. Un second couplage (28) relie la soupape (26) à un contrôle manuel sur le distributeur. De préférence, la soupape (26) tourne entre les positions fermée et ouverte. La buse (20) est également incorporée à un pistolet distributeur, lequel comporte un contrôle manuel sur la poignée, pour l'activation de la soupape .(26) entre lesdites positions, coagissant pour expulser le fluide à travers la buse (20). On décrit également un kit pour ensemble buse dans un distributeur manuel qui comprend la buse (20) et une extrémité de buse remplaçable (23). Le kit peut aussi comprendre une ou plusieurs extrémités de buse remplaçables (23), un capuchon d'extrémité remplaçable (305), et un instrument de nettoyage (100) pour la buse.
