Abstract

SUIVANT LE BREVET PRINCIPAL, UN BOITIER RENFERMANT DES RONDELLES ELASTIQUES EST MONTE OSCILLANT SUR LES DEUX FLASQUES D'UNE MOUFLE AUTOUR DE DEUX TOURILLONS. UN CARTER FIXE CONTRE LE BOITIER RENFERME L'ENSEMBLE DU DISPOSITIF MULTIPLICATEUR DONT LA CREMAILLERE EST RELIEE A L'INTERIEUR DU BOITIER PAR UN ELEMENT TRAVERSANT DES LUMIERES MENAGEES DANS LA PAROI DU BOITIER ET A L'ARRIERE DU CARTER. SELON L'ADDITION, CE CARTER AVEC L'ENSEMBLE DU DISPOSITIF MULTIPLICATEUR ET LE CADRAN DE LECTURE EST FIXE, EN AVANT DE L'UN DES FLASQUES DE LA MOUFLE, SUR L'UN DES TOURILLONS PERMETTANT L'OSCILLATION DU BOITIER. UNE LUMIERE EST MENAGEE DANS CE TOURILLON POUR PERMETTRE LE PASSAGE DE L'ELEMENT AUQUEL EST FIXEE LA CREMAILLERE. LE CARTER OSCILLE AINSI AVEC LE BOITIER, A L'INTERIEUR D'UN MANCHON DE PROTECTION FIXE AU FLASQUE.
