Abstract

LA INVENCION SE REFIERE A UN GENERADOR (1) QUE CONSTA DE UNA CARCASA CILINDRICA (2) CUYA PARED LATERAL (3) VA CERRADA POR AMBOS EXTREMOS. UNA PLACA TRANSVERSAL (6) DIVIDE LA CARCASA (2) EN UNA PARTE SUPERIOR (9) Y UNA PARTE INFERIOR (10). LA PARTE SUPERIOR (9) CONTIENE UN TUBO (16) QUE SEPARA DE FORMA ESTANCA DOS CAMARAS DE COMBUSTION (17, 18) PROVISTAS CADA UNA DE UNA CARGA PIROTECNICA (19, 20). EL DISPOSITIVO ELECTRICO DE ENCENDIDO (5) ESTA CONSTITUIDO POR UN INICIADOR DE DOBLE CABEZA (21, 22) CON UNA SOLA ALIMENTACION ELECTRICA. LAS DOS CABEZAS (21, 22) PUEDEN IR INCORPORADAS A UN PUENTE DE COMUNICACION PROVISTO DE CUATRO INTERRUPTORES COMBINADOS A UN CIRCUITO DE DIODOS. ASI, SE PUEDE O BIEN INICIAR UNA SOLA CABEZA (21, 22) A ELEGIR, O BIEN INICIAR LAS DOS CON UN DESFASE PROGRAMADO EN EL TIEMPO. EL GENERADOR DE LA INVENCION PERMITE CONSTITUIR UN GENERADOR PROGRESIVO PARA EL INFLADO DE UN COJIN DE PROTECCION.
