Cam 1 reciprocates along fixed guides a-a and has symmetrical triangular contour b. Follower 2 reciprocates in fixed guide B. The displacements of cam 1 and follower 2 are related by the equation s₂=s₁*tan(β), where β is the angle between contour b and the axis of guides a-a. The rates of rise and return of follower 2 are constant and equal. Impacts occur upon reversal of cam 1 and follower 2. Follower 2 is held in contact with cam 1 by spring 3.
