This invention is related to a mechanical torque generator (MTG) (11), the cost, the maintenance costs and the energy consumption of which have been minimized, as much as possible, since the reaction forces, the reaction moments and the frictional forces at the joints that connect the mechanism to the ground have been minimized as much as possible; which does not possess any actuators; and which can generate any desired torque variation. MTG (11) may be obtained by using 3 novel kinematic chains. By using these kinematic chains, it is also possible to obtain general purpose mechanisms, which have advantages similar to the MTG (11); which may include an actuator; which may generate relative rotational motion at a joint as any desired function of relative translational motion at another joint; which may be used in many different fields such as hydraulic and pneumatic machines, internal combustion engines and compressors.
