Abstract

Soudure avec languette d’étanchéité Un aspect de l’invention concerne un secteur de distributeur haute pression (1) comprenant deux monopales (10, 11) brasées entre elles par une brasure (12) placé sur un plan de joint (21) orienté d’amont en aval, il est caractérisé en ce que la brasure (12) est disposée sur une partie amont du plan de joint (2), qu’elle est plus courte axialement que le plan de joint (2) et qu’une partie aval du plan de joint (2) se poursuit par une échancrure (30) des deux monopales (10, 11) et dans laquelle est disposée une languette (4) d’étanchéité. Figure à publier avec l’abrégé : Figure 2Welding with sealing tab One aspect of the invention relates to a high-pressure distributor sector (1) comprising two single blades (10, 11) brazed together by a braze (12) placed on a joint plane (21) oriented opposite each other. upstream to downstream, it is characterized in that the solder (12) is arranged on an upstream part of the joint plane (2), that it is axially shorter than the joint plane (2) and that a part downstream of the joint plane (2) continues with a notch (30) of the two single blades (10, 11) and in which is arranged a tongue (4) for sealing. Figure to be published with abstract: Figure 2
