Abstract

Se describe una bomba formada por un alojamiento (10) que tiene una entrada (11) para la conexion a una fuente de fluido y una salida (12) para el fluido bombeado. Un rotor (15) es giratorio dentro de alojamiento y la entrada (11) y la salida (12) se separan alrededor de la trayectoria del rotor (15) en el alojamiento. El rotor (15) tiene superficies 16a, 16b, 16c, 16d) que forman, con el alojamiento (10), las camaras cerradas (18a, 18b, 18c, 18d) que viajan alrededor del alojamiento (10) para transportar el fluido desde la entrada (11) a la salida (12). El alojamiento (10) lleva un sello (14) que esta ubicado entre la entrada (11) y la salida (12) en la direccion de viaje del rotor (15). El sello (14) co-opera con las superficies del rotor (16a, 16b, 16c, 16d) mientras que las superficies (16a, 1616b, 16c, 16d) pasan entre la salida (12) y la entrada (11) para prevenir la formacion de una camara durante el paso y asi prevenir que el fluido fluya desde la salida (12) a la entrada (11). Tal bomba se produce facil y de forma economica y es particularmente util en aplicaciones medicas.
