Abstract

L'invention est du domaine des articulations à rotule. Elle vise plus précisément un dispositif d'articulation à rotule à tête creuse, notamment destinée à être montée sur une tubulure d'échappement de moteur à combustion interne, caractérisé par le fait qu'est prévue sur la face intérieure de l'enveloppe externe de la rotule au moins une gouttière connectée, d'une part, par au moins un passage traversant ladite enveloppe à des moyens d'alimentation en fluide de refroidissement de la rotule, d'autre part, à au moins un passage traversant la paroi de la tête de rotule de façon à permettre l'évacuation dudit fluide Application aux raccordements des tubulures d'échappement de moteurs aux dispositifs anti-pollution de post-combustion à réacteur thermique.
