Beschreibung
Zusammenfassung:	The invention relates to a valve comprising a pressurized-fluid inlet and a fluid outlet, and having: - a fixed plate with first channels, - a shutter with second channels, the shutter being movable between: o an open position in which the shutter is spaced apart from the plate, the first channels and the second channels being in fluid communication and allowing the passage of the fluid, o a closed position in which the shutter is in contact with the plate, the first channels and the second channels not being in fluid communication and blocking the passage of the fluid, - a piezoelectric actuator acting on the shutter to move it between the closed position and the open position, - the inlet is formed in such a way that, in use, the pressurized fluid exerts a force on an active face of the shutter so as to force it towards the closed position. The invention also relates to an electricity-generating system having such a valve.
