Abstract

PROCEDIMIENTO Y DISPOSITIVO ASOCIADO PARA CONTROL DE ELEMENTO RECUPERADOR PROPULSADO NEUMATICAMENTE EN INSTALACION DE LAMINACION DE PASO DE PEREGRINO. COMPRENDE UN RECINTO DE COMPRENSION (1) PARA ALOJAMIENTO DEL PISTON (5) DE BOMBA, UN RECINTO DE COMPRESION (4) PARA ALOJAMIENTO DEL PISTON (6) DEL ELEMENTO RECUPERADOR Y UNA CONDUCCION (3) DE UNION DE AMBOS RECINTOS (1,4). VARIANDO LA POSICION DEL PISTON (5), PROPULSADO A TRAVES DE MANIVELA, SE CONSIGUE, DURANTE EL MOVIMIENTO DEL PISTON NEUMATICO (5), UNA VARIACION ADICIONAL DE VOLUMEN Y DE PRESION.
