Cam 1 reciprocates along fixed guides a-a and has a triangular contour with inclined straight portions b and d. Follower 2 reciprocates in fixed guide B. The displacements of cam 1 and follower 2 during follower rise are related by the equation s₂=s₁*(sin(β)/sin(α-β)) where s₁ and s₂ are the displacements of cam 1 and follower 2, P is the angle between portion b of the cam contour and the axis of guides a-a, and α is the angle between the axis of follower motion and the axis of guides a-a. The corresponding equation for follower return is s₂=s₁*(sin(γ)/sin(α+γ)) where γ is the angle between portion d of the cam contour and the axis of guides a-a. The rise and return velocities of follower 2 are constant but different. An impact occurs upon follower reversal. Follower 2 is held in contact with cam 1 by spring 3.
