Abstract
Drive apparatus for linear displacement of a stem; especially for regulator rods of nuclear reactors, characterized in that a plurality of axially spaced flares are arranged on the stem, which is surrounded by an upper or respectively lower core, which are movable in an axial direction for a limited distance, the upper or respectively lower thereof being surrounded by an upper or respectively lower coupling core, of which each is also axially movable with respect to its corresponding main core, so that an upper or respectively lower ratchet element hinged to the Corresponding core is rotated inward and engages on the stem, when the main core and the coupling core move together, with control elements being provided that move the upper or respectively lower core and join and separate them and move the upper core or respectively lower simultaneously either for a certain distance together or the upper core up and the lower core down.
