Abstract

Les chambres de combustion (41, 43) entrant respectivement en communication, en fonction du déplacement des pistons, avec les carters (21, 23) équipés de passages d'admission d'air (51, 53) avec soupapes à lames souples (55, 57), un conduit (71) s'étend entre les premier et second carters et un papillon (73) situé dans ce conduit est mobile entre des positions d'ouverture et de fermeture pour permettre et empêcher, respectivement, l'écoulement de fluide entre les premier et second carters.
