Abstract

UN DISPOSITIVO DISPENSADOR DE LIQUIDO (2) Y UN METODO PARA DISPENSAR LIQUIDO. EL DISPOSITIVO (2) INCLUYE UN CONTENEDOR HUECO HERMETICO AL LIQUIDO Y AL GAS (4), UNA MEMBRANA HERMETICA AL GAS Y LIQUIDO FLEXIBLE (18, 130) CON AL MENOS UNA CONVOLUCION (132) Y DISPUESTA A TRAVES DEL INTERIOR DEL CONTENEDOR Y QUE DIVIDE EL MISMO EN UNA CAMARA DE PROPULSION (36) Y UNA CAMARA DE LIQUIDO (24) , UN PUERTO DE SALIDA (28) DESDE LA CAMARA DE LIQUIDO (24), DOS SUSTANCIAS QUIMICAS MUTUAMENTE REACTIVAS (38, 40) EN LA CAMARA DE PROPULSION, PERO QUE REACCIONAN AL CONTACTO PARA FORMAR UN GAS PROPULSOR. AL GENERARSE EL GAS, ESTE SE EXPANDE CONTRA LA MEMBRANA (18, 130), PRESURIZANDO LA CAMARA DE LIQUIDO (24) PARA EXPULSAR EL LIQUIDO CONTENIDO A TRAVES DEL PUERTO DE SALIDA. UN VALVULA DE ESCAPE DE PRESION (45), ADECUADA PARA SU USO CON EL DISPOSITIVO, PERMITE QUE EL GAS SE ESCAPE DESDE EL MISMO CUANDO LA PRESION EXCEDA UN NIVEL PREDETERMICNADO.
