Abstract

L'invention concerne une pompe à vis à excentrique ou un moteur à vis à excentrique (1), dont les faces frontales de l'enveloppe (19) comportent des joints ou des moyens de protection (33, 34) formant une seule pièce avec le revêtement (32) de l'enveloppe (19). Ceci permet d'améliorer l'étanchéité de la paroi intérieure (21) de l'enveloppe (19) vis-à-vis du fluide transporté et, en outre, d'empêcher efficacement que la liaison intime entre le matériau de l'enveloppe (19) et du revêtement (32) soit interrompue.
