Abstract
The invention relates to a cylinder head () for an internal combustion engine having at least one cylinder, having at least one valve seat ring () for a lifting valve, wherein the valve seat ring () is surrounded by an annular cooling duct () for a coolant that is at least partly molded into the cylinder head (), wherein the cooling duct () at least partly surrounds the valve seat ring and extends between an inlet () and at least one outlet (). In order to reduce the valve wear, provision is made for a plurality of inlets () to open into the cooling duct (), wherein the inlets () are preferably arranged asymmetrically in relation to a meridian plane (δ) of the valve seat ring () through the outlet ().
