Abstract

LA INVENCION SE REFIERE A UNA BOMBA ROTATIVA QUE COMPRENDE UN ESTATOR (1) PERFORADO POR UN ALOJAMIENTO (11) DELIMITADO POR UNA PARED LATERAL CILINDRICA (110), UN ROTOR (2) CILINDRICO, TANGENTE EN EL INTERIOR DEL ALOJAMIENTO (11), Y SUSCEPTIBLE DE SER ARRASTRADO EN ROTACION ALREDEDOR DE UN EJE (X) DESCENTRADO RESPECTO A ESTE ALOJAMIENTO, Y UNA ALETA (3) QUE ATRAVIESA DIAMETRALMENTE EL ROTOR Y QUE PRESENTA DOS BORDES OPUESTOS (31, 32) APOYADOS SOBRE LA PARED LATERAL (110) DEL ALOJAMIENTO Y SEPARADOS UNO DE OTRO POR UNA DISTANCIA SOMETIDA A VARIACIONES DURANTE LA ROTACION DEL ROTOR. SEGUN LA INVENCION, LA ALETA (3) ESTA REALIZADA EN UNA HOJA DE UN MATERIAL QUE OFRECE UNA RESISTENCIA ELASTICA A LA FLEXION, PRESENTANDO ESTA HOJA UNA PARTE ONDULADA (33, 34) QUE PERMITE ABSORBER LAS VARIACIONES DE LA DISTANCIA ENTRE LOS BORDES OPUESTOS (31, 32) DE LA ALETA.
