57	Abstract	AB	Die Erfindung betrifft Zylinderkopf (1) für eine Brennkraftmaschine mit zumindest einem Zylinder, mit zumindest einem Ventilsitzring (3) für ein Hubventil, wobei der Ventilsitzring (3) von einem zumindest teilweise in den Zylinderkopf (1) eingeformten ringförmigen Kühlkanal (4) für ein Kühlmittel umgeben ist, wobei der Kühlkanal (4) den Ventilsitzring zumindest teilweise umgibt und sich zwischen zumindest einem Eintritt (5, 15, 25) und zumindest einem Austritt (6) erstreckt. Um den Ventilverschleiß zu vermindern, ist vorgesehen, dass mehrere Eintritte (5, 15, 25) in den Kühlkanal (4) einmünden, wobei vorzugsweise die Eintritte (5, 15, 25) asymmetrisch in Bezug zu einer Meridianebene (δ) des Ventilsitzrings (3) durch den Austritt (6) angeordnet sind.
