Beschreibung
Zusammenfassung:	The internal pressure P1 of the hollow body of a pneumatic structural element that comprises a hollow body ( 1 ), at least two traction elements ( 4 ) and at least one compression member ( 2 ) can be electrothermally varied by means of a fluid. The hollow body ( 1 ) houses a void ( 12 ) which is filled with a gas ( 15 ), and a container ( 9 ) which contains a volatile liquid ( 10 ). Said liquid ( 10 ) can be heated or cooled by means of a heat pump ( 13 ). Said heat pump ( 13 ) thermally contacts the liquid ( 10 ) via lamellas ( 24 ). A pressure sensor ( 14 ) measures the pressure inside the void ( 12 ). A cable ( 16 ) links the sensor ( 14 ) and the heat pump ( 13 ) with control and regulating electronics ( 23 ).
