Title (EN) TWIN VANE ROTARY VACUUM PUMP
(FR) POMPE À VIDE ROTATIVE À DEUX PALETTES
Abstract:
(EN) Vacuum pump (1), comprising a housing (2) having an inlet (4) and an outlet (6) and defining a chamber (8) within the housing (2), a rotor (10) for rotational movement about a rotational axis (AR) within the chamber (8), and at least a first and a second vane (22, 24) received in respective first and seconds slots (16, 18) formed in the rotor (10). The first and second slots (16, 18) are substantially parallel to each other, and a length (Lv) of each vane (22, 24) is larger than a length (Ls) of the respective slot. Production method of such a vacuum pump.
(FR) L'invention concerne une pompe à vide (1), comprenant un boîtier (2) ayant une entrée (4) et une sortie (6) et définissant une chambre (8) au sein du boîtier (2), un rotor (10) pour un mouvement rotatif autour d'un axe de rotation (AR) au sein de la chambre (8) et au moins une première et une seconde palette (22, 24) reçues dans des première et seconde fentes respectives (16, 18) formées dans le rotor (10). Les première et seconde fentes (16, 18) sont sensiblement parallèles l'une à l'autre, et une longueur (Lv) de chaque palette (22, 24) est supérieure à une longueur (Ls) de la fente respective. L'invention concerne également un procédé de production d'une telle pompe à vide.
