Centrifugal governor 7 moves its sleeve 8 up or down along axis O-O, turning lever 9 about fixed axis A. Four-bar linkage ABCD converts turning motion of lever 9 into turning motion of bent lever 5. Eccentric 1 rotates about fixed axis E, actuating lever 3 which is connected by turning pair F to slider 4. Slider 4 moves along fixed guide a. Spring 10 holds lever 3 in contact with lever 5 and eccentric 1. When eccentric 1 rotates about axis E, lever 3 oscillates about the tip b of bent lever 5 whose position is determined by centrifugal governor 7. As a result, slider 4 reciprocates with strokes whose length depends on the angular velocity of the governor.
