Abstract (en)
[origin: EP0933527A2] Engaged with the toothed rim (34) are two adjacently located drive pistons (12,12') which have toothed rod-type teeth (13,13'). The drive pistons through fluid operation are movable in parallel directions opposite to one another, in order to provoke a rotary movement (26) of the driven part between two end positions. A position indication device (3), by working in conjunction with the two drive pistons, makes possible the indication of an intermediate position between the end positions.
