One end of flexible link a, connecting a system of pulleys rotating about moving and fixed axes, is attached at point K to the base. The other end of link a is wound on drum 8 which is rigidly attached to pinion 1 and rotates about fixed axis H. Pinion 1 meshes with gear rack 7. Rules 2, 3, 4, 5 and 6, connected by turning pairs A, B, C, D and E to the movable pulleys, are held in definite positions by applied forces q. If the movable pulleys are displaced from their initial positions A₀, B₀, C₀, D₀ and E₀ to the positions A, B, C, D and E, the displacement z of rule 7 equals the sum of the displacements of rules 2, 3, 4, 5 and 6, i.e. z=∑z_i; with limits [2;6].
