Abstract

L'invention concerne un moteur à deux temps à combustion interne, comportant un carter-pompe et un cylindre. Ledit carter-pompe est divisé en deux chambres par une membrane, chacune de ces chambre est reliée audit cylindre par au moins un canal de transfert, de l'air pur est admis dans une des chambres et de l'air carburé dans l'autre chambre, le canal de transfert correspondant à la chambre d'air pur est agencé pour être ouvert pendant le fonctionnement du moteur avant le canal de transfert correspondant à la chambre d'air carburé.
