Abstract

Un compensador comprender un alojamiento y una rampa de deslizamiento que es desplazable a lo largo de un asiento de deslizamiento; la rampa de deslizamiento incluye una porcion de canal de flujo, la sigue hacia un codo, el cual, en el estado de operacion, es decir cuando está fluyendo un material derretido de polímero caliente a través del compensador, es congruente con una porcion de canal de flujo adicional; las dos porciones de canal de flujo tienen rebordes en sus caras extremas para la instalacion del compensador en un codo dentro de una línea derretida a través de la cual fluye un material de derretido de polímero que ocaciona las expansiones lineales de línea derretida debidas a la temperatura incrementada.
