Abstract

L'invention concerne un pot d'échappement avec bloc de catalyseur. Pot d'échappement caractérisé en ce que l'enveloppe se compose de deux coquilles 1a, 1b, munies de moulures circonférentielles 1c, et en ce que par assemblage, elle peut être serrée de telle sorte que le bloc de catalyseur 6, muni d'un revêtement adhérent de matière souple, par exemple sous forme de natte 7, est maintenu par précharge et par enfoncement du revêtement dans les moulures circonferentielles.
