Abstract (en)
[origin: EP1033498A2] The setting cylinder control process involves subjecting the locked piston (4) to an external shock force. The piston is locked by a hydraulic pressure which is dependent on the current working position. This pressure acts against the direction of application of the external force via the setting path.
