  • Valve seat insert with soft landing insert design with contoured radii
    Patent number: 11480075
    Abstract: A valve seat insert includes a top convex arcuate blend for improving fluid flow, and a valve seating surface for slowing down valve recession. The valve seating surface includes a radially outer convex arcuate segment defining an outer radius of curvature forming a first wear crown for contacting the valve at an early wear state, a radially inner convex arcuate segment defining an inner radius of curvature forming a second wear crown for contacting the valve at a later wear state, and a linear segment extending between the radially outer convex arcuate segment and the radially inner convex arcuate segment.
    Type: Grant
    Filed: June 10, 2021
    Date of Patent: October 25, 2022
    Assignee: Caterpillar Inc.
