Abstract

EN UN ACCIONAMIENTO LINEAL EMBOLO/CILINDRO PIROTECNICO EN UN TENSADOR DE CINTURON SE SEGURIDAD EL CILINDRO (10) MUESTRA UN EXTREMO (12) LIBRE EN FORMA DE CONO TRUNCADO. EL EMBOLO (14) SE ENCUENTRA SUJETO EN EL EXTREMO DE UN CABLE (16) DE TRACCION Y MUESTRA EN SU OTRO EXTREMO (12) LIBRE DEL CILINDRO (10) UNA PIEZA (20), QUE SE REDUCE EN FORMA DE CONO TRUNCADO CON EL EXTREMO DIRIGIDO HACIA EL CILINDRO. UN EMBOLO (22) ANULAR SE DESPLAZA EN ARRASTRE DE ROZAMIENTO SOBRE LA PIEZA (20) REDUCIDA DEL EMBOLO (14). ESTA DISPOSICION FORMA UNA SEGURIDAD DE INTERCEPCION DE EMBOLO QUE SIN TENER UNA LONGITUD DE CILINDRO GRANDE, FRENA EL EMBOLO BAJO TRANSFORMACION DE ENERGIA.
