Abstract

Ensemble comprenant un pointeau indémontable en position fermé, pistolet pulvérisateur et procédé d’installation associés L’invention concerne un ensemble comprenant un pointeau (12) s’étendant selon une direction longitudinale et une pièce de raccordement (14) entourant le pointeau (12). Le pointeau (12) est déplaçable selon la direction longitudinale par rapport à la pièce de raccordement (14) entre au moins une position ouverte et une position fermée. La pièce de raccordement (14) comprend une portion de connexion (40) et une portion de serrage (42) apte à être entraînée par un outil de manière à appliquer au pointeau (12) une force de serrage ou desserrage. L’ensemble (10) comprend un capot (16) inséparable du pointeau (12) et solidaire du pointeau (12) pour tout mouvement, le capot (16) recouvrant la portion de serrage (42) dans la position fermée, le capot (16) laissant la portion de serrage (42) accessible dans la position ouverte. Figure pour l'abrégé : figure 1Assembly comprising a needle that cannot be dismantled in the closed position, associated spray gun and method of installation The invention relates to an assembly comprising a needle (12) extending in a longitudinal direction and a connecting piece (14) surrounding the needle (12) . The needle (12) is movable in the longitudinal direction relative to the connecting piece (14) between at least one open position and one closed position. The connecting piece (14) comprises a connection portion (40) and a clamping portion (42) capable of being driven by a tool so as to apply a clamping or loosening force to the needle (12). The assembly (10) comprises a cover (16) inseparable from the needle (12) and secured to the needle (12) for any movement, the cover (16) covering the clamping portion (42) in the closed position, the cover ( 16) leaving the clamping portion (42) accessible in the open position.
