Abstract

EL INVENTO TIENE POR OBJETO UNA BOMBA DE VACIO DE VARIOS ESCALONES EN LA QUE EN EL ULTIMO ESCALON ATMOSFERICO SE PREVE UNA BOMBA IMPELENTE LUBRICADA CON ACEITE O CON FUNCIONAMIENTO SECO A LA QUE SE ANTEPONE EN EL LADO DE VACIO AL MENOS OTRA BOMBA. SE OBTIENE UNA REDUCCION DEL CONSUMO DE ACEITE Y UN AUMENTO SIMULTANEO DEL RENDIMIENTO POR EL HECHO DE QUE LA BOMBA (2) ANTEPUESTA ES UNA BOMBA DE ANILLO DE GAS.
