Abstract

Une pompe à vide selon l'inventin est formée de l'assemblage de deux demi-coquilles (101, 102) de stator et de deux pièces rapportées d'extrémité (31, 32) avec interposition d'un joint d'étanchéité (33) monobloc continu. Le joint d'étanchéité (33) comprend deux parties annulaires d'extrémité (34, 35) généralement parallèles l'une à l'autre et raccordées par deux longerons (36, 37) qui leur sont généralement perpendiculaires. On diminue ainsi le nombre de pièces à assembler pour réaliser une pompe à vide séche multi-étagée, tout en assurant une étanchéité satisfaisante vis à vis de l'atmosphère extérieure.
