Hackworth's valve-gear

By

The Hackworth valve-gear differs from the Klug valve-gear in the way that the eccentric rod's suspension point, in stead of vacillate in a curve, moves to-and-fro in a straight line by means of a block sliding in a slotted guide. Changing the angle of the guide rails changes the engine's rotation.
