Abstract

Moteur à combustion interne à piston alternatif. Dans le piston alternatif 3 d'un moteur à combustion interne sont aménagées deux chambres de combustion superposées 4 et 5 qui communiquent par un passage 6 dont la section d'écoulement peut être modifiée automatiquement, sous l'action de la pression régnant dans la chambre d'injection 4, par déplacement, en antagonisme à un ressort 21, d'un manchon 18 porté par le corps 19 de la buse d'injection 9. Le dispositif permet l'adaptation automatique aux conditions du moment du déroulement de la combustion.
