Abstract

L'invention concerne un cylindre entièrement intégré apte à tourner en va-et-vient. Un bloc collecteur (5) est positionné au-dessus d'un carter de cylindre horizontal (2) et comprend un corps de cylindre (8). Un canal de carburant droit (5.1) du bloc collecteur présente une forme en L. Un canal de carburant de capuchon d'extrémité gauche (3.1) présente une forme qui s'apparente à un C et comprend un orifice de carburant supérieur positionné au niveau d'une surface latérale droite (3.5) d'un capuchon d'extrémité gauche (3). Un canal de carburant de capuchon d'extrémité droite est symétrique au canal de carburant de capuchon d'extrémité gauche (3.1). Un tube de carburant horizontal et rigide (9) est disposé entre un orifice de carburant supérieur d'un canal de carburant de capuchon d'extrémité et un orifice de carburant latéral d'un canal de carburant du bloc de collecteur du même côté que ce dernier. Le tube de carburant horizontal et rigide (9) est fixé au niveau d'une partie supérieure du carter de cylindre horizontal (2) du même côté que ce dernier.
