Abstract

LA INVENCION SE REFIERE A UNA BOMBA VOLUMETRICA. TIENE POR OBJETO UNA BOMBA VOLUMETRICA, COMPUESTA DE UN ROTOR QUE GIRA EN UN ESTATOR CON UN JUEGO DETERMINADO. SE UTILIZA PARA EL BOMBEO DE UN GAS O DE UNA MEZCLA DE GAS DE MASA MOLECULAR DETERMINADA. SE CARACTERIZA POR EL HECHO DE LLEVAR UNOS MEDIOS PARA INYECTAR, EN EL JUEGO CITADO, UN GAS DE MASA MOLECULAR MAS ELEVADA QUE LA DEL GAS O DE LA MEZCLA DE GAS BOMBEADO. APLICACION EN LAS BOMBAS DE PALETAS, EN LAS BOMBAS ROOTS, EN LAS BOMBAS DE DOBLE TORNILLOS CILINDRICOS O CONICOS, ETC.
