Abstract
UN GENERADOR DE IMPULSO SISMICO COMPRENDE UN CUERPO 1 QUE DISPONE DE UNA CAMARA INTERNA 2 PRESURIZABLE CON GAS, JUNTO A UNA SEGUNDA CAMARA 6 QUE CONTIENE UN FLUIDO. UN MIEMBRO 21 DE VALVULA DE MARIPOSA GIRA SOBRE UN EJE PIVOTE PARA CERRAR UN ORIFICIO 24 QUE COMUNICA CON LA PRIMERA CAMARA. UN PESTILLO 22 LIBERABLE RETIERE EL MIEMBRO DE VALVULA DE MARIPOSA EN LA POSICION CERRADA Y UN PISTON 13 QUE FUNCIONA POR GAS SE MUEVE EN DESLIZAMIENTO DENTRO DE UN CILINDRO 12 ASOCIADO. CUANDO LA PRIMERA CAMARA 2 SE PRESURIZA CON GAS Y EL MIEMBRO 21 DE VALVULA DE MARIPOSA SE DEJA LIBRE DE SU POSICION CERRADA PARA DESCUBRIR EL ORIFICIO 24, EL PISTON 13 SE MUEVE PARA QUE HAYA COMUNICACION ENTRE LAS CAMARAS 2,6 Y SE GENERE UNA ONDA DE CHOQUE EN LA SEGUNDA CAMARA. LA SEGUNDA CAMARA TIENE MEDIOS DE SALIDA 7 PARA PERMITIR QUE SE TRANSMITA UN IMPULSO DE ENERGIA DESDE LA SEGUNDA CAMARA EN RESPUESTA A LA ONCHA DE CHOQUE GENERADA EN LA SEGUNDA CAMARA. EL MIEMBRO DE LA VALVULA DE MARIPOSA SE PUEDE DISPONER PARA QUESE ABRA, DE MANERA QUE LA APERTURA COMPLETA DEL ORIFICIO 24, LA PERDIDA DE PRESION DE GAS DEL ORIFICIO 24, Y LA RESPUESTA DEL PISTON 13 DEN LUGAR A QUE SE CONSIGA MUY RAPIDAMENTE LA COMUNICACION ENTRE LAS CAMARAS.
