Abstract (en)
[origin: EP3000998A1] A valve seat insert (10A, 10B, 10C) for a cylinder head (104) of an internal combustion engine (100) comprises a ring-shaped body (20) defining a passage (22) for enabling a fluid to pass through the body (20) along an axial direction (Z) from an entrance side (24) to an exit side (26) of the valve seat insert (10A, 10B, 10C), wherein the body (20) comprises an entrance side section (32) with a first contact surface section (42), and a valve sealing surface section (46), an exit side section (34) with a second contact surface section (48), and an arch section (36) axially extending from the entrance side section (32) to the exit side section (34) and decreasing in material thickness from the entrance side section (32) towards the exit side section (34) up to a minimum thickness axial position (P) that is located in the half of the arch section (36) being close to the exit side section (34). Thereby, a more load resistant structure of the valve seat insert (10A, 10B, 10C) can be provided.
