Abstract
Perfeccionamientos en máquinas de cambio de agujas de ferrocarril, caracterizados porque se dispone en cada máquina un primer accionador de funcionamiento hidráulico neumático, para cambiar las partes móviles de los raíles entre posiciones extremas en las cuales se establecen vías respectivas, y un primer dispositivo de válvula acoplado al primer accionador para abrir o cerrar selectivamente o eliminar un paso o conducto que se acopla a lados opuestos de un pistón, de paleta o diafragma, o elemento móvil similar sensible a la diferencial de presión del primer accionador por lo que, cuando el primer dispositivo de válvula se cierra o elimina dicho paso o conducto, se puede establecer una diferencial de presión de fluido hidráulico o neumático a través del elemento móvil para hacer funcionar el primer accionador y cambiar por lo tanto las partes móviles de los raíles, y cuando el primer dispositivo de válvula abre el paso o conducto, se puede intercambiar directamente fluido hidráulico o neumático entre uno u otro lado del elemento móvil para permitir que las partes móviles de los raíles se muevan desde la primera posición extrema hasta la otra posición extrema por el paso de un vehículo de ferrocarril que toma las agujas por los talones.
