Abstract

Culasse de moteur thermique comportant un arbre à came, des soupapes présentant chacune un linguet allongé (10) comprenant à une extrémité un pivot, à l’autre extrémité une face d’appui sur une tige de soupape (6), et un rouleau (16) présentant un axe parallèle à celui de l’arbre à cames, et comportant un bras de retenu fixe (20) présentant une extrémité de butée du linguet (26) limitant sa course lors d’une fermeture de la soupape, ce bras de retenu (20) comprenant un passage intérieur de fluide de lubrification présentant un orifice de sortie (28) tourné vers le contact entre le rouleau (16) et la came en appui sur ce rouleau. Figure 1Heat engine cylinder head comprising a camshaft, valves each having an elongated latch (10) comprising at one end a pivot, at the other end a bearing face on a valve stem (6), and a roller ( 16) having an axis parallel to that of the camshaft, and comprising a fixed retaining arm (20) having a stop end of the latch (26) limiting its stroke when the valve closes, this arm of retained (20) comprising an internal passage of lubricating fluid having an outlet orifice (28) facing the contact between the roller (16) and the cam resting on this roller.
