The lengths of the links comply with the condition: A͞C=B͞C=C͞D=B͞E=F͞E=E͞G. When crank 3 rotates about fixed axis K, points D and G travel in straight lines passing through points A and F. The axes of the cylinders coincide with straight lines FG and AD. The displacement s₅ of slider 5 is related to the displacement of piston 1 by the equation s₅=sqrt(s₁(2B͞G-s₁)).
