With a total of 3 patents to his name, Waydelis has developed innovative technologies that enhance engine performance and efficiency.

Latest Patents

One of his latest patents is for a variable cam phaser and method of assembly. This invention features a variable cam phaser with drive and driven members connected by helical splines of an annular phase control piston and a lash control piston. The axial motion of these components varies the angular phase relation between the drive and driven members. A single wave spring biases the pistons apart to take up lash in the splines, while a return spring biases the phase control piston to an initial phase setting. The design includes a driven member that comprises two components, allowing for pre-timing of the members during assembly.

Another significant patent by Waydelis is for a camshaft phasing drive with wedge actuators. This phase adjuster for engine camshafts includes a sprocket driving a camshaft attached hub through paired wedge packs. These wedge packs transfer torque and maintain a lash-free connection. The design utilizes a plunger actuated by engine oil pressure to axially move alternate active wedges, thereby changing the phase angle between the sprocket and camshaft. A three-way valve is incorporated to minimize oil flow requirements.
