Abstract

UN ACCIONADOR NEUMATICO LINEAL CON UN DISPOSITIVO DE BLOQUEO DE ACCION REVERSIBLE PARA PREAJUSTAR EL ACCIONADOR CON UN FRENO ACTIVO O PASIVO. EL ACCIONADOR CONSTA DE UN PISTON (13) QUE PUEDE OSCILAR DENTRO DE UN CILINDRO (10); EL MOVIMIENTO LINEAL DEL PISTON (13) PROVOCA LA ROTACION DE UN EJE ROSCADO (20) QUE HAY CONECTADO A UN GENERADOR DE SEÑALES (25) QUE CONTINUAMENTE PROVEE LA POSICION RELATIVA DEL PISTON (13). UN DISPOSITIVO DE BLOQUEO QUE CONSTA DE DOS MIEMBROS DE PISTON INTERCONECTADOS (34, 36) QUE SE PUEDEN ACCIONAR NEUMATICAMENTE EN DIRECCIONES OPUESTAS Y UNOS CONDUCTOS (46, 47) QUE SUMINISTRAN AIRE A PRESION Y SE PUEDEN SELECCIONAR DURANTE EL MONTAJE PARA QUE ACTIVEN EL DISPOSITIVO DE BLOQUEO COMO SI FUERA UN FRENO ACTIVO O UN FRENO PASIVO, RESPECTIVAMENTE, PARA BLOQUEAR EL PISTON DEL ACCIONADOR (13).
