In a cylindre head (1) of a water cooled internal combustion engine, which may be provided by pressure casting, all the water volumes (2 to@5) in the form of recesses extend up to the interface cylindre-head cylindre block and surround substantially the combustion chambers (6). These water volumes (2 to 5) are connected to the water jacket of the cylindre block (13) by means of passageways (16 to 19) provided in the cylindre head gasket (14) and are interconnected by means of transverse conduits (7, 7') and of a longitudinal, lateral conduit (8). The top of the longitudinal conduit (8) is the highest point of the water volumes (2 to 5) and of the conduits (7, 7' and 8) and the longitudinal conduit (8) is provided with a water outlet (9). The cooling of the cylindre head (1) is effectively controlled by means of the particular arrangement of the water volumes (2 to 5), the transverse conduits (7, 7') and the passageways (16 to 19) of the cylindre head gasket with respect to the main elements of the cylindre head (1). |
