Abstract
Procedimiento para la activación de un accionador capacitivo (Pn) por medio de un circuito de control (ST), especialmente de al menos una válvula de inyección de combustible accionada de manera piezoeléctrica de un motor de combustión interna, donde el accionador (Pn) es cargado con una tensión teórica (Us = U1 + U2; Usn = U1 + U2n) aplicada en un circuito en serie de un condensador de carga (C1) y de un condensador de recarga (C2) y es descargado en el condensador de recarga (C2), que es cargado en este caso a un valor de la tensión (U2, U2n) predeterminado, caracterizado porque - la capacidad del condensador de carga (C1) es mucho mayor que la capacidad del condensador de recarga (C2) ( C1 >> C2), y - porque la carga restante remanente del accionador (Pn) es cargada en el condensador de carga (C1), cuando el condensador de recarga (C2) ha alcanzado el valor predeterminado de la tensión (U2, U2n).
