Patent

CA 2217448

A quick disconnect nozzle comprising a nozzle body, a spray tip, and an annular sealing member interposed therebetween. The tip is adapted to be inserted axially into the body and then rotated. When the tip is rotated, camming lugs on the tip and body coact to draw the tip axially toward the body and compress the sealing member. Detents in the form of flexible curved ribs are carried by the tip and resiliently pop into curved pockets in the body to releasably hold the tip in its installed position. The sealing member is an O- ring which is carried by the tip and which is removable from the body as a unit with the tip. An inner seal is provided between mutually converging tapered walls of the nozzle tip and nozzle body adjacent the inner end portion of the nozzle tip.

L'invention concerne une tuyère démontable rapidement comprenant un corps tuyère, un embout de pulvérisation et un joint annulaire placé entre ces derniers. L'embout est conçu pour être inséré axialement dans le corps, puis tourné. Lorsque l'embout a été tourné, des languettes à cames situées sur l'embout et sur le corps agissent ensuite pour tirer l'embout axialement en direction du corps et comprimer le joint. Des positionneurs sous forme de nervures courbes flexibles sont portés par l'embout et s'enfilent de manière élastique dans des poches incurvées du corps pour tenir de manière amovible l'embout dans sa position installée. Le joint est une bague en O qui est portée par l'embout et qui peut être séparée du corps en même temps que l'embout. Un joint intérieur est placé entre les parois coniques réciproquement convergentes de l'embout et du corps, adjacentes à la partie finale intérieure de l'embout de la tuyère.
