Abstract

a. Tête avec des groupes de nervures perpendiculaires et parallèles à l'axe du cylindre et des surfaces déflectrices d'air, un groupe de nervures perpendiculaires à l'axe au-dessus des canaux d'admission et d'échappement et un groupe de nervures parallèles à l'axe dans le domaine supérieur de la tête et des guides de soupapes. b. Tête caractérisée en ce que la surface déflectrice 25 au-dessus de la tête forme dans la partie antérieure de la tête, avec les nervures supérieures perpendiculaires à l'axe, un canal d'air 25 qui passe entre les guides de soupape 12, 13 et sur les canaux d'admission et d'échappement se prolongeant par plusieurs canaux d'air 38 entre les nervures parallèles à l'axe et la surface déflectrice 23, avec derrière la tête un orifice de sortie de l'air à l'air libre. c. Tête de soupape assurant un refroidissement optimal par l'air d'un moteur monocylindrique.
