Abstract

La présente invention concerne une pompe à vide (1). À l'intérieur de ladite pompe qui possède une aube unique (3), certains espaces (9) entre l'aube unique (3) et un corps (2) ou un couvercle de la pompe (1) peuvent entraîner une réduction des performances de la pompe à vide (1). Afin d'améliorer les performances de la pompe à vide (1) qui possède une aube unique (3), l'invention propose de réduire lesdits espaces (9) au moyen d'un élément flexible (22) qui comprend deux bras (28 et 29). Cet élément flexible (22) est agencé sur au moins une des faces (13 et 14) de l'aube unique (3). Les bras (28 et 29) peuvent être aplatis ou redressés selon l'espace devant être rempli entre l'aube unique (3) et le corps (2) ou le couvercle de la pompe (1).
