A crankshaft with a crank arm is connected to a reciprocatable piston or sshead by a connecting rod. By having the connecting rod length equal to the crank arm length, a motion whose equation is y=2a sin .alpha. is imparted to the piston or crosshead. In the equation y is the linear position of the piston or crosshead, a is either the crank arm or connecting rod length, and .alpha. is constant angular rotation of the crankshaft.
