Slider 1 turns about fixed axis 0. Link 3 has the form of a bent lever. Link 3 is connected by a sliding pair to slider 1 and by turning pair A to slider 2 which moves along fixed guides p-p whose axis is parallel to axis 0x. When slider 1 turns about axis 0, point D of link 3 describes Pankappa curve q-q with the equation ρD=0͞D=((c-a*cos(ϕ))/sin(ϕ) or a²x²=(c-y)²(x²+y²) where a and c = constant dimensions of the mechanism, complying with the condition c>a; ϕ = polar angle between vector ρD and polar axis 0x.
