The lengths of the links comply with the condition: B͞C=C͞D=A͞C. The axes of the cylinders are perpendicular to each other. Crank 1 turns about fixed axis A and is connected by turning pair C to connecting rod 2 which, in turn, is connected by turning pairs to slides 3 and 4. The stroke s of the pistons is four times the length A͞C of crank 1. Sliders 3 and 4 move in parallel planes.
