Latest Patents

One of Egan's latest patents is the "Friction index modifier for damper," which improves upon U.S. Pat. No. 3,440,899 by McGavern. This invention features a first plurality of shear liquid filled cavities defined by through apertures in the elastomer member. The improvement lies in the addition of a second plurality of shear liquid filled cavities located in the inertia member at a surface interfaced with the elastomer member. This construction increases the total volume of shear liquid, thereby enhancing the damping action of the torsional vibration damper. Another significant patent is the "Constant belt tension device," which is a constant-tension spring device for the accessory belt of an automobile engine. This device includes a cylinder with elastomer rings mounted within each end. A rod passes through each elastomer ring, with spaced shoulders bearing against the elastomer rings. The device maintains desired tension within the accessory belt, compensating for changes in temperature, humidity, and aging that would otherwise affect belt length and tension.
