Abstract
Dispositivo para preparar infusiones para la extracción de los constituyentes de una substancia con la ayuda de un líquido calentado contenido en un recipiente provisto con un elemento calefactor eléctrico, siendo expulsado dicho líquido por el calor, al menos parcialmente, fuera de dicho recipiente y puesto en contacto con la substancia de la cual deben ser extraídos constituyentes, caracterizado porque el elemento calefactor está eléctricamente conectado en serie con un resistor con un coeficiente de temperatura positivo elevado, siendo el valor de resistencia de dicho resistor inicialmente inferior, cuando es suministrada una tensión de alimentación eléctrica, que el del elemento calefactor, pero saltando a un valor tan alto, después que ha sido alcanzada la temperatura a la cual el líquido se pone en contacto con la substancia de la cual deben ser extraídos constituyentes, que la corriente eléctrica que pasa a través del elemento calefactor es justamente suficiente para mantener al líquido que retorna al recipiente a la temperatura elevada deseada.
