Abstract
A valve train for an internal combustion engine includes a camshaft and a variable cam phaser connected to the camshaft for driving the camshaft. The variable cam phaser includes an input shaft rotationally coupled to a crankshaft drive member; and an output shaft rotationally coupled to the camshaft and coaxial with the input shaft. Electrically operated adjusting means drivingly connect the input and output shafts enabling the input and output shafts to be selectively, angularly adjusted while maintaining driving engagement therebetween. The input and output shafts are coupled to the drive member and camshaft via respective, rotationally stiff, flexible couplings.
