With a total of 2 patents to his name, Strader's work has had a meaningful impact on automotive engineering.
Latest Patents
Strader's latest patents include innovative designs that enhance the efficiency of viscous fluid fan clutches. The first patent, titled "Electromagnetically actuated valve plate for a viscous fluid fan clutch," describes a fan clutch assembly that utilizes a flexible, ferromagnetic valve plate. This valve plate controls fluid flow through a pump plate into a shear zone. When the electromagnetic coil is energized, the resulting flux deflects the valve plate away from the pump plate, allowing fluid gates to open. Conversely, when the coil is de-energized, the valve plate returns to its original position, closing the fluid gates.
The second patent, "Electromagnetic control assembly and method for a viscous fluid fan," outlines a fan clutch assembly that features an electromagnetic control assembly for actuating a rotatable valve plate. This design includes a rotatable shaft connected to the valve plate and a ferromagnetic element that is slidably mounted on the shaft. When the electromagnetic coil is energized, the ferromagnetic element is attracted, causing it to slide and rotate the shaft, which in turn opens the valve plate.
