Patent number: 11441512Abstract: A cooling system for a cylinder head of an internal combustion engine includes a cylindrical seat configured to engage an exhaust valve, a first coolant jacket, and a first conduit. The exhaust valve seat defines an annular cooling passage extending along a circumference of the cylindrical seat. A wall of the cylindrical seat defines a first opening into the annular cooling passage and a second opening into the annular cooling passage, where the first opening is positioned diametrically opposite to the second opening. The first coolant jacket is positioned adjacent to a fire-deck of the internal combustion engine. The first conduit fluidly couples the first coolant jacket to the at least one of the first opening and the second opening to the annular cooling passage in the exhaust valve seat.Type: GrantFiled: May 4, 2021Date of Patent: September 13, 2022Assignee: Cummins Inc.Inventors: Andrew P. Perr, Robin J. Bremmer, Philipe F. Saad, Akintomide K. Akinola, Rick Vaughan Lewis, Jr., Dennis King Chan
