Abstract

Perfeccionamientos en unidades reguladoras neumáticas para controlar una magnitud variable en un proceso operativo, particularmente en regulación programada, caracterizados porque comprende dos toberas (7,8) iguales, en comunicación neumática con dicho relé (2) de la misma unidad, dos láminas obturadoras (12a, 112a), una para cada tobera, mantenidas en posición de obturación de las correspondientes toberas por respectivos elementos deformables elásticamente (13, 113) y un elemento (16) soportando por dicha unidad (1) de mido oscilante alrededor de un eje paralelo a dichas toberas (7,8) y que actúa sobre una u otra de dichas láminas (12, 112a), siendo desplazado dicho elemento (16) angularmente en un sentido o en el sentido opuesto alrededor de dicho eje por un actuador (20) que funciona sobre la base de la diferencia entre el valor efectivo del proceso y el valor deseado y variable según un programa prefijado.
