Abstract

Patente de Invenção:<B>"PROCESSO E DISPOSITIVO PARA COMANDO DE UM ELEMENTO DE REGULAGEM CAPACITIVO"<D>. Para obter um curso (ds) constante de um elemento de regulagem capacitivo, por exemplo, para uma válvula injetora de combustível de um motor de combustão, em uma ampla faixa de temperatura, o elemento de regulagem é carregado, pelo fato de lhe ser alimentada uma energia pre-determinada, isto é, um condensador é descarregado de modo definido. Alternativamente, a corrente alimentada ao elemento de regulagem e a tensão decrescente no mesmo são multiplicadas, o produto integrado, e o valor integral comparado com um valor teórico predeterminado. O processo de carga é interrompido, quando o valor integral atingir ou ultrapassar o valor teórico.
