Link 1, turning about fixed axis 0, is connected by sliding pairs to sliders 2 and 3. Slider 4 moves along fixed guides t-t whose axis is perpendicular to axis Ox. Cross-piece CB of slider 4 is connected by turning pair C to link 5. Link 5 moves in cross- shaped slider 2 which has guides perpendicular to each other. Slider 3 is connected by turning pair B to slider 4. When link 1 turns about axis 0, point D of slider 2 describes curve s-s, accompanying a cissoid of Diocles, wi th the equation ρD=0͞D=2a/cos(ϕ)+a*cos(ϕ) or y²=x²(x-a)/(2a-x) where a = diameter of circle p-p ϕ = polar angle between vector ρD and polar axis 0x.
