Abstract

L'invenzione riguarda una valvola a caratteristica proporzionale la cui grandezza d'uscita è proporzionale ad un segnale d'entrata elettrico, la valvola a caratteristica proporzionale essendo azionata preferibilmente da un elettromagnete di tipo proporzionale, che può venire comandato proporzionalmente alla tensione alla tensione o alla corrente mediante un segnale di comando, l'elettromagnete di tipo proporzionale venendo comandato direttamente con "l'alta tensione", vale a dire con la tensione di rete raddrizzata, mediante una disposizione circuitale di comando venendo assicurato che la bobina dell'elettromagnete non venga sovraccaricata, particolarmente non venga superato un valore di corrente massimo. Inoltre, si può rinunciare alla parte di rete necessaria nell'odierno stato della tecnica.
