Slotted link 2, rotating about fixed axis A, is connected by a sliding pair to slider 3 which rotates about the axis of pin B of link 1. Link 1 is designed as a gear rotating freely on fixed ring a. Gear 1 is driven by pinion 6 which rotates about fixed axis D. Connecting rod 7 is connected by turning pairs E and F to slotted link 2 and slider 4. Slotted link 2 has a slot along which slider 8 can be adjusted by means of screw device 5. This changes the length A͞E of link 2 and thereby varies the stroke of slider 4 in fixed guides d-d. When pinion 6 rotates, slider 4 reciprocates.
