Abstract
Con l'invenzione, un apparecchio a fluido, ad esempio un gruppo a pistone e cilindro, viene rifornito di fluido tramite una valvola di commutazione a cadenza aperta o chiusa. Le punte di depressione che si manifestano durante la chiusura della valvola di commutazione sul suo lato di uscita nonché le forze di inerzia del fluido in arrivo vengono sfruttate per condurre fluido supplementare al dispositivo idraulico tramite una valvola di non ritorno che, da un raccordo a bassa pressione e rispettivamente da un serbatoio, porta all'apparecchio a fluido.
