an angle to the longitudinal axis a of the turbine device or machine when the control links 14 perform the pivoting motion about the pivot point 15 and the control yoke arms 12 perform the pivoting motion about the pivot point 10 the other pivot points 16 and 13 of the control cylinder or sleeve 8 each describe a segment of a circular arc only the axial component of which serves for controlling the guide vanes or stator vanes 5 the component vertical to the axis a which in the usual control displacements is relatively small can be readily accommodated by a sufficient radial play or clearance of the slide blocks 6a fig2 of the control levers 6 in the annular grooves or channels 7 since a considerable temperature gradient between the control sleeve 8 and the machine housing 1 can arise during operation of the turbine device or machine described it is advantageous to provide a certain radial play or clearance 21 of the control sleeve 8 in the pivot axis 13 and 16 transverse to the longitudinal axis a to compensate for the differential thermal expansion supplementary longitudinal stops can be provided to avoid a swimming motion of the control sleeve 8 the drive means for the control yoke 11 or equivalent structure can be manual or can be powered and can operate through a control or regulating mechanism to engage the control yoke 11 at a suitable position in the example shown in fig3 a hand wheel 17.
