Abstract
Disclosed is a fail-safe fluidic actuation system () having a safety position, comprising a control element () having at least one first and one second chamber (); having a working circuit () with a motor/pump device (), wherein the control element can be actuated by means of the working circuit at least in the operational state. Furthermore, the actuating system comprises a discharge valve () which, in a failure state, is placed into a pass-through position in order to discharge fluid from the second chamber, and the safety circuit is designed such that, in the operational state, an inflow decoupled from the store can be generated into the control element by means of the working circuit with the motor/pump device, wherein by means of the safety circuit, in a failure state, an inflow fully decoupled from the working circuit with the motor/pump device is provided into the first chamber by means of the store, wherein the control element has three chambers, and wherein the safety circuit is designed such that, in the operational state, an inflow decoupled from the store can be generated into the third chamber () by means of the working circuit with the motor/pump device.
