A reciprocating machine includes a housing (12) and piston means (20) that are cyclically relatively displaceable along an axis (11) to define a variable volume working chamber (50). There is further provided air inlet means and fuel inlet means (100) admitting air and fuel to the working chamber for forming an ignitable mixture after compression of the air therein, and means to exhaust combustion products from the working chamber. The variable volume working chamber (50) includes at least two sub-chambers, a combustion chamber (54) and a main chamber (52) mutually displaced on the axis (11) and in communication at a cross section (53) at which gas in the combustion chamber (54) may expand at least partially laterally as it flows from the combustion chamber (54) into the main chamber (52). The air admission means, the exhaust means and the chambers (52, 54) are arranged so that a swirl of gas is generated and maintained about the axis (11) in both chambers (52, 54) during operation of the machine. The combustion chamber (54) is sealed and defined laterally and at one end by integral heat resistant and/or low thermal conductivity wall structure (40) having a surrounding heat insulation jacket (48) and associated heat dissipation means (47, 49) arranged so that, during operation of the machine, the surfaces (42a, 44) of the wall structure bounding the combustion chamber are maintained at a temperature which is substantially higher than wall surfaces (31) bounding the main chamber (52).

L'invention porte sur une machine alternative comportant un logement (12), des pistons (20) se déplaçant cycliquement le long d'un axe (11) de manière à délimiter une chambre (50) de compression de volume variable, des moyens (100) d'admission d'air et de carburant dans la chambre de compression de manière à former un mélange inflammable après compression de l'air s'y trouvant, et des moyens d'expulsion des produits de combustion de la chambre de compression. La chambre à volume variable (50) comporte au moins deux sous-chambres c.-à-d. une chambre de combustion (54) et une chambre principale (52) se déplaçant ensemble sur l'axe (11) et communiquant ensemble à une intersection (53) où les gaz de la chambre de combustion (54) peuvent s'expanser au moins partiellement latéralement en passant de la chambre de combustion (54) dans la chambre principale (52). Le moyen d'admission d'air, le moyen d'expulsion, et les chambres (52, 54) sont conçus pour créer et maintenir un tourbillon de gaz autour de l'axe (11) dans les deux chambres (52, 54) pendant la marche. La chambre de combustion (54) est étanche, et bornée latéralement et à l'une de ses extrémités par une paroi (40) monolithique thermorésistante et/ou de faible conductivité thermique munie d'une chemise isolante (48) et de moyens associés de dissipation de chaleur (47, 49) conçus pour que pendant la marche les surfaces (42a, 44) de ladite paroi ne soient portées à une température sensiblement plus élevée que celle (31) de la paroi entourant la chambre principale (52).
