摘要:
A cooled valve seat ring for a cylinder head of an internal combustion engine, having a valve seat part, wherein the cooled valve seat ring comprises a sheet-metal cooling channel consisting of a thin sheet of steel and which is connected with a coolant circuit via bores which serve as inflow and outflow for a coolant, wherein the cooled valve seat ring is connected with the cylinder head material by casting technology. In one embodiment, there can be a cooled valve seat ring that is connected with a cylinder head material via a laminate casting process. There can also be a cooled valve seat ring that has an alfin layer for a connection with the cylinder head material. In addition, the cooling channel can be welded onto or soldered onto the valve seat part. Furthermore, the sheet-metal cooling channel can be connected with the valve seat part so as to form a gas-tight seal.
