Latest Patents

One of his latest patents is titled "Valve seat insert for engine head having venturi flow crowns and seating surface profiled for limiting valve recession." This invention features a valve seat insert designed for gas exchange valves, such as intake valves, which control the gas exchange of a cylinder. The insert body includes an inner and outer peripheral surface, along with a valve seating surface that is structured to contact the gas exchange valve at a closed position. The design is profiled to limit valve recession, incorporating an arrangement of linear and curved segments that form wear crowns to accommodate different wear states. Additionally, the inner peripheral surface is structured with an incoming flow crown and a venturi that accelerates incoming gas flow.

Another significant patent by Smallidge is the "Double-crowned valve seat insert having seating surface formed of hard-facing material." This invention also pertains to gas exchange valves and features a similar insert body structure. The valve seating surface is designed to contact the gas exchange valve at a closed position and is profiled to limit valve recession. It includes a base material and a hard-facing material that is metallurgically bonded to the base material, forming the valve seating surface.
