Electro-fluidic systems are devices managing fluids (air, gas, liquids…) such as servovalves, pumps, electro-hydraulic jacks (EHA), injectors, ink jet printers, thrusters, dampers … A class of new electro-fluidic systems is emerging benefiting from the advantages provided by new smart actuators :
CEDRAT TECHNOLOGIES has developed or helped customers to develop new active valves and various electro-fluidic systems, using its broad experience in all these actuation techniques. Some examples are given hereafter or in our related publications on valves.
The VIPER (Valve hIgh PERformances for flow control separation in aircraft) Cleansky project aims at developing, manufacturing and testing piezoelectric valves to accurately control the air flow (Active Flow Control Actuators) on transport and business aircraft.
