Abstract

The drive is actuated by an element under pressure, in which the rod is actuated by a control piston provided with locking elements and is displaced in a guide tube with stop notches, the system being characterised by the connection of the first or upper control piston to a second or lower control piston also having locking elements, devices being provided for alternate disengagement of the locking elements so as to permit alternate axial movement of the two control pistons from a stop notch on each occasion. The control piston when in the rest position is locked in the stop notches.
