Abstract

Mode d'assemblage des calottes permettant une réduction de diamètre extérieur du servofrein. Les deux calottes 2 et 3 sont accouplées pour former une enveloppe 1 et maintenir entre elles le pourtour d'un diaphragme 4. La calotte 2 a une forme de disque avec un pourtour présentant une double courbure formant une rainure 5 pour le bord du diaphragme 4. La calotte 3, en forme de coupe, a une partie légèrement évasée 6 qui comporte des cavités 7 dans lesquelles viennent s'enclencher les saillies 9 du bord de la calotte 2.
