Abstract

L’invention a pour objet un dispositif (1) de dépôt d’un revêtement sur une paroi fermée (21) d’une culasse (2) délimitant une ouverture (14) destinée à recevoir une soupape afin de fabriquer un siège (3) de soupape, ledit dispositif possédant une buse (7) de sortie allongée et apte à diffuser un matériau constitutif du revêtement au moyen d’au moins un gaz chaud à très haute vitesse. Selon l’invention, le dispositif comprend un moyen de mise en rotation de la buse (7) permettant à ladite buse (7) d’effectuer au moins une fois un déplacement rotatif sur 360° afin de déposer le revêtement sur la totalité de ladite paroi (11). Figure pour l’abrégé : Fig. 1The subject of the invention is a device (1) for depositing a coating on a closed wall (21) of a cylinder head (2) delimiting an opening (14) intended to receive a valve in order to manufacture a seat (3) valve, said device having an elongated outlet nozzle (7) capable of diffusing a material constituting the coating by means of at least one hot gas at very high speed. According to the invention, the device comprises means for rotating the nozzle (7) allowing said nozzle (7) to perform at least once a rotary movement over 360° in order to deposit the coating on the whole of said wall (11).
