Abstract
Se proporcionan dispositivos 300 de activación que se pueden usar para cambiar la orientación de una o más aletas, y métodos relacionados que separan un primer extremo de una barra 310 de activación y un segundo fluido en un extremo opuesto de la barra de activación. Un dispositivo de activación incluye una barra de activación y un cuerpo 320 del dispositivo de activación configurado para permitir que la barra de activación se mueva a lo largo del eje dentro del cuerpo del dispositivo de activación, y tiene un reborde 322 de entrada configurado para permitir que un tercer fluido entre en el espacio entre el cuerpo 320 del dispositivo de activación y la barra 310 de activación, y un reborde 324 de salida configurado para permitir que el tercer fluido salga del cuerpo del dispositivo de activación. Además de proporcionar un sello de fluido entre el primer fluido y el segundo fluido, el tercer fluido también puede calentar la barra de activación, lo cual evita la formación de hielo.
