Abstract
Dispositivo para controlar el flujo de un material plástico calentado hasta el estado fluido a través de una carcasa (1), en particular un dispositivo de filtrado o un dispositivo de conmutación para el material plástico, con un conducto de paso (2) que atraviesa la carcasa (1) y un émbolo (8) de sección circular conducido con posibilidad de desplazamiento longitudinal en un orificio (7) de la carcasa (1), transversal a la dirección longitudinal del conducto de paso (2), cuyo émbolo (8) cruza el conducto de paso (2), donde en una parte del émbolo (19) que sobresale de la carcasa (1), fuera de la carcasa (1), está colocado un anillo rascador no cortado (23), para el cual está previsto un tope (25) unido a la carcasa (1), de manera que el émbolo (8) sea desplazable con relación al anillo rascador (23) caracterizado porque el diámetro interior (d2) del anillo rascador (23) es inferior al diámetro (d0) del orificio (7) de la carcasa (1) y también menor que el diámetro (d1) del extremo (21) de la parte de émbolo (19) alejado de la carcasa (1) y que sobresale de la carcasa (1), cuando éste está en sus condiciones más frías de trabajo, de manera que el anillo rascador (23) está siempre calado con tensión inicial sobre la parte de émbolo (19).
