<p>Apparatus for rotating a member (30,45) solid with and made to translate by the rod (27,41A) or body of the cylinder (29C,41C) of a cylinder-piston system (29,41), characterized in that the rod (27,41A) is connected to the piston (28,41P) so as to be able to rotate idly relative thereto and in that the outer surface either of the rod (27,41A) or the body of the cylinder (29C,41C) is of prismatic (or slotted that is splined) construction and slides guided within a suitable prismatic (or slotted) seat formed inside a bush (36,36') that can rotate, suitably supported, inside a stationary structure (42,42'), coaxial with said system (29,41), said structure (42,42') being solid with the frame to which the stationary part of the system is fixed, and said bush (36,36') being driven into rotation by a gear (44,44') solid therewith or by equivalent means.</p> |
