À cet effet, la chambre de cylindre est divisée en n chambres partielles dans chacune desquelles un piston peut osciller, chaque chambre partielle est divisée en deux chambres de combustion (22, 24) par le piston pouvant osciller à l'intérieur de celle-ci et chaque chambre de combustion est reliée de préférence à un raccord par lequel est amené un gaz précomprimé.
