Abstract

A cylinder head for an internal combustion engine has at least one receptacle socket, penetrating a coolant chamber, for a spark plug and/or an injection valve. At one end, the socket rests tightly, with a frustoconical seating face, against a corresponding seating face of a seat embodied on a lower cylinder head wall, and at its other end the socket is retained in the associated cylinder head wall and is pressed axially against the seat. In order to attain particularly intensive cooling in the vicinity of the nozzle of the injection valve and/or the spark plug, the seating face on the respective socket is embodied as a female cone, and the associated seating face on the respective seat is embodied as a male cone, and the associated end faces of the respective socket are open toward the coolant chamber.
