ABSTRACT:
A control sleeve is provided in an axial turbine device, an axial translation of which controls the stator vanes of the turbine device. In order to obtain as precise as possible a motion of the control sleeve in the axial direction without high friction forces and without the danger of jamming, a parallelogram linkage guide arrangement is provided. The parallelogram linkage guide arrangement is formed by a control yoke and control links arranged parallel thereto having pivot axes in the machine housing and further pivot axes in the control sleeve.
