Abstract

Un mecanismo de maniobra de las agujas de vías férreas con mando eléctrico, esencialmente caracterizado por la combinación nueva de un motor eléctrico con dos sentidos de rotación, de una bomba volumétrica directamente acoplada a él, y de un gato hidráulico de doble efecto que ataca a la barra de maniobra de la aguja por mediación de una pieza de escuadra con eje en un cárter estanco que contiene el aceite que asegura a la vez la lubricación del mecanismo y el funcionamiento del gato, por un circuito cerrado "bomba-gato-depósito"
