Abstract

Motore endotermico (1) avente una coppia di valvole di aspirazione (5,6) e/o una coppia di valvole di scarico (5',6') per ogni cilindro (3), in cui ciascuna coppia di valvole omologhe (5,6; 5',6') è comandata da un rispettivo organo (9,9') di azionamento costituito da un elemento trasversale (17) atto a cooperare con le valvole stesse e da uno stelo (19) cooperante con rispettivi mezzi di guida (45,45') fissi alla testa (4) del motore (1); l'elemento trasversale (17) è disposto ad un'estremità inferiore dello stelo (19) ed i suddetti mezzi di guida (45,45') sono disposti al di sopra delle valvole (5,6,5',6').(Fig. 2)Endothermic engine (1) having a pair of intake valves (5,6) and / or a pair of exhaust valves (5 ', 6') for each cylinder (3), in which each pair of homologated valves (5, 6; 5 ', 6') is controlled by a respective actuation member (9,9 ') consisting of a transverse element (17) adapted to cooperate with the valves themselves and by a stem (19) cooperating with respective guide means (45.45 ') fixed to the head (4) of the motor (1); the transverse element (17) is arranged at a lower end of the stem (19) and the aforesaid guiding means (45.45 ') are arranged above the valves (5.6.5', 6 '). (Fig. 2)
