Abstract
Nell'ambito di un sistema di azionamento idraulico per la cappotta di un veicolo viene installata, nel condotto idraulico (8) che porta verso la camera (6) preposta all'apertura della cappotta medesima, una valvola di ritegno (23), la cui funzione viene soppressa in fase di chiusura della stessa. In tal modo si può assicurare con semplici mezzi che risulti impossibile una parziale apertura della cappotta per effetto della resistenza dell'aria o altro. (Figura 1).As part of a hydraulic actuation system for the hood of a vehicle, a check valve (23) is installed in the hydraulic conduit (8) which leads to the chamber (6) in charge of opening the hood. function is suppressed when it is closed. In this way it can be ensured by simple means that a partial opening of the canopy is impossible due to the resistance of the air or other. (Figure 1).
