Link 1. rotating about fixed axis A, is connected by a sliding pair to cross-shaped slider 2 which has guides perpendicular to each other. Link 5 is connected by a sliding pair to slider 2 and by turning pairs B and C to slÍders 3 and 4. Slider 3 moves along fixed guides p-p whose axis coincides with axis Ay, and slider 4 along fixed guides t-t whose axis coincides with axis Ax. When link 1 rotates about axis A, point D of slider 2 describes four-leafed rose q-q with the equation ρD=A͞D=a*cos(2ϕ) where a = 0.5B͞C ϕ = polar angle between vector ρD and polar axis Ax.
