Abstract
Ce moteur, comportant pour chacun de ses cylindres un piston auxiliaire muni d'une tige de piston, mobile dans un logement ménagé dans la culasse et débouchant dans la chambre de combustion, est caractérisé en ce que le logement 8 du piston auxiliaire 9 délimite avec ce dernier, autour de sa tige 10, une chambre annulaire 12 alimentée en liquide sous pression à travers un clapet anti-retour 14, la tige du piston auxiliaire comportant un alésage axial 15 dans lequel coulisse un tiroir 17 dont la position est asservie à un paramètre représentatif des conditions de fonctionnement du moteur, ledit tiroir coopérant avec au moins un trou de fuite 16 ménagé à travers ladite tige creuse 10 du piston auxiliaire 9 pour constituer un trajet de décharge de ladite chambre 12.
