ROBINET MELANGEUR A POIGNEE UNIQUE

IL COMPORTE UN CORPS COMPORTANT DES ENTREES ET UNE SORTIE D'EVACUATION, ET DES DISQUES CERAMIQUES DONT LA POSITION MUTUELLE DETERMINE LA PROPORTION DE MELANGE DE L'EAU CHAUDE ET DE L'EAU FROIDE. UN DISQUE CERAMIQUE EST DEPLACE PAR UN LEVIER 7 QUI EST FIXE PAR DES PALIERS A UNE PIECE ROTATIVE 8 MONTEE DE FACON A TOURNER A L'INTERIEUR DU CORPS. POUR LIMITER LE MOUVEMENT DE ROTATION DE CETTE PIECE 8, EN MEME TEMPS QUE LE LEVIER 7, LA PIECE ROTATIVE 8 COMPORTE DES SAILLIES AXIALES 11, TANDIS QUE LA PARTIE 1A COMPORTE RESPECTIVEMENT AU MOINS UNE SAILLIE AXIALE 12. CEPENDANT, LES SAILLIES 11, 12 DE CES DIFFERENTS COMPOSANTS NE SE CHEVAUCHENT PAS EN DIRECTION RADIALE, MAIS UNE PIECE DE LIMITATION 13 AU MOINS EST INTERPOSEE ENTRE LES COMPOSANTS 8, 1A; ELLE PEUT S'INSERER ENTRE LES SAILLIES 11 DE L'ELEMENT 8 ET CHEVAUCHER RADIALEMENT LES SAILLIES 12 DE L'AUTRE ELEMENT 1A. The invention relates to a single-grip valve having a valve body with water inlets and a water discharge outlet and ceramic discs fitted in the body, the mutual position of the discs determining the mixing ratio of cold and hot water. One ceramic disc is moved by a lever which is attached with bearings to a turning piece fitted to turn inside the body. In order to limit the turning movement of this turning piece and, together with it, that of the lever, one of the members, the turning part and the body part surrounding it, is equipped with axial protrusions spaced around it and the other has respectively at least one axial protrusion. However, the protrusions of the different members do not overlap each other in the radial direction, but between the said members there is fitted at least one detachable limiting piece which can engage between the protrusions of one member and radially overlaps the protrusions of the other member.
