Abstract

Una disposizione compatta di testata (11) per motori a combustione interna, in particolare a due cilindri, comprendente almeno una coppia di cilindri dotati di apertura di valvola (53) con relativa valvola (56), associata a ciascun cilindro essendo prevista una camera (14, 15) che da un lato è collegata alla valvola (56) e dall'altro è collegata a mezzi per l'alimentazione di miscele carburante, entro ciascuna camera (14, 15) essendo previsto un pistone (17, 18) per iniettare entro il rispettivo cilindro una miscela generata nella camera (14, 15), i pistoni (17, 18) essendo movimentati da una biella (23) comandata da una trasmissione positiva (44, 47) azionata da un albero motore, ove ciascuna biella (23) dei pistoni è imperniata ruotabile su un elemento ad albero (24, 25, 26), che è rotante in una bussola (31) vincolata nella testata (11) e che è rigidamente collegato alla trasmissione positiva, l'elemento ad albero e la bussola essendo dotati di condotti (33, 34, 35) di alimentazione della miscela carburante che sono allineabili in fase di rotazione dell'elemento ad albero (24, 25, 26).
