The mechanism contains a slider crank kinematic chain connected in parallel with a slider crank. The kinematic chain RRT´s joints are connected with the coupler and piston of the slider crank. By means of changing the geometrical lengths of the mechanism´s links, the coupler point M describe a range of coupler curves.
