Title (DE) ZYLINDERKOPF FÜR EINE BRENNKRAFTMASCHINE
(EN) CYLINDER HEAD FOR AN INTERNAL COMBUSTION ENGINE
(FR) TÊTE DE CYLINDRE POUR UN MOTEUR A COMBUSTION INTERNE
Abstract:
(DE) Die Erfindung betrifft einen Zylinderkopf (1) und ein Verfahren zur Fertigung für eine Brennkraftmaschine mit zumindest einem Zylinder und zumindest zwei Ventilsitzen pro Zylinder für jeweils ein Gaswechselventil mit einer Kühlmantelanordnung, wobei zur Kühlung der Ventilsitze eine Ringkanalanordnung mit zumindest zwei Ringkanälen (17) vorgesehen ist. Aufgabe der vorliegenden Erfindung ist es einen Zylinderkopf (1) anzugeben, der einfach fertigbar ist. Das wird erfindungsgemäß dadurch gelöst, dass zumindest ein Ringkanal (17) an einen, einen Ventilsitz bildenden, Ventilsitzring (9) grenzt, wobei vorzugsweise jeder Ringkanal (17) von je einem Ventilsitzring (9) begrenzt ist.
(EN) The invention relates to a cylinder head (1) and a method for manufacturing for an internal combustion engine with at least one cylinder and at least two valve seats per cylinder for in each case one gas exchange valve with a cooling jacket arrangement, wherein a ring channel arrangement with at least two ring channels (17) is provided for cooling the valve seats. It is a problem of the present invention to indicate a cylinder head (1) which can be manufactured simply. According to the invention, this is achieved by virtue of the fact that at least one ring channel (17) adjoins a valve seat ring (9) which forms a valve seat, wherein each ring channel (17) is preferably delimited by in each case one valve seat ring (9).
(FR) L'invention concerne une tête de cylindre (1) et un procédé de production pour un moteur à combustion interne, comprenant au moins un cylindre et au moins deux sièges de soupape par cylindre pour respectivement une soupape d'échange de gaz pourvue d'un ensemble de gaines de refroidissement, un ensemble de canaux annulaires pourvu d'au moins deux canaux annulaires (17) étant prévu pour le refroidissement des sièges de soupape. L'invention vise à proposer une tête de cylindre (1) simple de fabrication. L'invention propose à cet effet qu'au moins un canal annulaire (17) jouxte une bague (9) de siège de soupape formant un siège de soupape, chaque canal annulaire (17) étant de préférence délimité par respectivement une bague (9) de siège de soupape.
