Abstract
Moteur à combustion interne à quatre temps et à pistons à mouvement alternatif. Il comporte des pistons épaulés dont une partie élargie travaille dans un alésage afin d'assumer la fonction d'un compresseur qui réalise une suralimentation de la chambre de combustion du moteur ou un mélange de carburant et d'air. Ce compresseur exécute deux courses de compression par cycle de fonctionnement du moteur. Domaine d'application : moteurs à combustion interne.
