The mechanism contains an inverted crank connected in series with a slider crank. The mechanism transforms the rotation movement of the crank into translation movement of the slider. The stroke of the slider depends on the geometric dimensions of the linkage.
The movie was generated for the geometrical dimensions: x = 15 mm, y = 60 mm, x1 = 20 mm, l1 = 25 mm, l3 = 55 mm, l´3 = 22 mm, l4 = 40 mm.
