Abstract

LA INVENCION SE REFIERE A UNA BOMBA DE RUEDA DENTADA CON DOS RUEDAS DENTADAS DE IMPULSION QUE ENGRANAN UNA CON OTRA, ACTUANDO CONJUNTAMENTE EN DIRECCION CIRCUNDANTE ANTES Y DETRAS DE UN PLANO QUE CONTIENE EL EJE DE LA RUEDA DENTADA CON UNA CONDUCCION DE PRESION Y UNA CONDUCCION DE ASPIRACION. DE ACUERDO CON LA INVENCION SE GUIA UN MEDIO DE BOMBEO TRANSPORTADO EN EXCESO A TRAVES DE UNA CONDUCCION ESPECIAL EN DIRECCION CIRCUNDANTE DE LAS RUEDAS DENTADAS DETRAS DE LA CONEXION DE LA CONDUCCION DE ASPIRACION EN EL ESPACIO DENTADO DE LAS RUEDAS DENTADAS DE IMPULSION, PARA EVITAR QUE APAREZCA EVENTUALMENTE CAVITACION.
