Abstract

a. Machine à deux cylindres en opposition l'un par rapport à l'autre ayant leurs pistons reliés à une partie médiane de pompage. b. Les pistons 14, 15 des cylindres 11, 12 et le piston de pompage 17 sont disposés excentriquement les uns par rapport aux autres et le cylindre de pompage interne à la partie médiane 10 a son diamètre plus petit que les diamètres internes des pistons 14, 15 et se deplace dans la zone de poussée des deux pistons. La chambre d'aspiration 28 et la chambre de compression 29 de la partie de pompage sont formées d'espaces vastes dans une partie 30 de la partie médiane de la machine, dont l'étendue radiale est supérieure au diamètre des cylindres 11, 12. La chambre de compression est à l'extérieur de la chambre d'aspiration et a son volume plus grand que celui de la chambre d'aspiration. c. Machine à deux temps utilisant comme carburant de l'huile pour moteurs Diesel.
