Abstract
Perfeccionamientos en los interruptores de vacío, que comprenden una carcasa hermética que aloja en vacío contactos montados sobre barras de contacto que llevan corriente y que son capaces de movimiento una respecto de otra así como un dispositivo adsorbedor, que comprende elemento adsorbedor dotado de un material adsorbente que puede adsorber los gases facultativamente presentes al producirse su evaporación por aplicación de calor generado por una corriente inducida, caracterizados porque se ha dispuesto una pantalla metálica entre el dispositivo adsorbedor y las paredes aisladas del interruptor de vacío, funcionando dicha pantalla como la superficie sobre la que está depositado el material adsorbente y estando dotado de hendiduras que impiden la producción de corrientes parásitas en la pantalla y porque el elemento adsorbedor emite el material adsorbente por evaporación en una sola ubicación, estando situados esta ubicación y la ubicación de las hendiduras de la pantalla una respecto de otra de tal forma que la barra de contacto que lleva tanto el elemento adsorbedor como la pantalla impida que el material adsorbente emane un material más allá de dicha pantalla.
