Abstract

L'invention concerne un moteur à deux temps à combustion interne comprenant un premier cylindre dans lequel se déplace un piston moteur et un deuxième cylindre dans lequel se déplace un équipage mobile d'équilibrage, les faces internes du piston moteur et de l'équipage mobile d'équilibrage délimitant la chambre d'un carter-pompe, la face externe du piston moteur délimitant une chambre de combustion et la face externe de l'équipage mobile d'équilibrage délimitant une chambre de compression auxiliaire. Il est prévu au moins un transfert, en lui-même connu, reliant la chambre du carter-pompe à la chambre de combustion pour l'admission de l'air carburé, et au moins une tubulure relie la chambre de compression auxiliaire à la chambre de combustion, des moyens étant prévus pour admettre de l'air pur dans la chambre de compression auxiliaire et le refouler par ladite tubulure, et les lumières d'admission d'air carburé et d'air pur étant disposées dans la paroi du premier cylindre de telle sorte que la (ou les) lumière(s) d'admission d'air pur soit ouverte au passage du piston moteur avant la (ou les lumière(s) d'admission d'air carburé.
