title = "Estimation of the hydraulic conditions in piezo-pilot-valves",
abstract = "Usually in servo valves a low electrical power is converted into a differential pressure, which controls by a furthermore piston the effective power in the form of a hydraulic power flow. Due to the short reaction time, piezo valves are particularly suitable as pilot stage. A direct connection to the control spool has been avoided due to the small stroke of piezo actor. By a direct connection of the piezo actor and the control piston the tolerances in which the pilot valve must be produced are very small and this results in very expensive prototypes. To advance in the estimates of the yield pressure and the flow rate the possibility of simulation should be investigated on an existing prototype of a direct piezo pilot stage.",
