Latest Patents
Ivan J Bruns holds a patent for a frustoconical valve stem sealing element. This patent describes a valve stem seal assembly that includes a rigid cylindrical shell and an annular resilient seal body contained entirely within the shell. Integral to the seal body is a frustoconical sealing element that is designed to engage a valve guide of an internal combustion engine. The sealing element converges radially inwardly, and upon installation of the assembly on a valve guide, the outer surface of the sealing element bends further radially inwardly to effectively seal the top surface of the guide. The seal body also features a stem sealing aperture, which in one preferred embodiment is designed to engage the valve stem without a spring. Additionally, the shell contains a circumferential array of tangs for retention of the assembly on the guide.
