Cam 1 rotates about fixed axis A and its contour a slides along the contour of cam 2 which turns about fixed axis B. Contour c of cam 2 slides along tip d of follower 3, reciprocating the follower in fixed guides D. The other end, e, of follower 3 slides along flat surface f of link 4 which turns about fixed axis E so that its flat surface k slides along tip n of valve rod 5. Rod 5 reciprocates in fixed cylinder 6. Follower 3 is held in contact with cam 2, and cam 2 with cam 1 by spring 7.
