A barrier of a vacuum pump prevents contamination from entering a vacuum pump air line. The barrier separates parts of the pump and is moveable between an initial state and a distended state. The barrier is assembled within the pump with a pre-load. When the vacuum source is applied to the barrier, the barrier achieves a distended state and when the vacuum source is released, the barrier incrementally self returns to an initial state. The geometry and material construction of the barrier, along with the pre-load, assists in returning the barrier on its own to the initial state from the distended state.

L'invention concerne une barrière de pompe à vide empêchant toute contamination de pénétrer dans un circuit d'air de pompe à vide. La barrière sépare des parties de la pompe et est mobile entre une position initiale et une position distendue. La barrière est assemblée dans la pompe avec une précharge. Lorsque la source de vide est appliquée à la barrière, la barrière adopte une position distendue et lorsque la source de vide est libérée, la barrière retourne automatiquement de manière incrémentale à une position initiale. La géométrie et la construction matérielle de la barrière, de même que la précharge, contribuent au retour automatique de la barrière à la position initiale à partir de la position distendue.
