Abstract

L'invention concerne un moteur à combustion interne et un système de lubrification à carter sec comportant une pompe de pression (11) pour alimenter en liquide de lubrification sous pression un circuit de lubrification à haute pression du moteur, à partir d'un réservoir (30) de liquide de lubrification, et une pompe d'assèchement (12) destinée à aspirer le liquide de lubrification tombé dans le carter inférieur (40) du moteur, appelé carter d'huile, et à le refouler dans ledit réservoir.
Selon l'invention, la pompe de pression et la pompe d'assèchement possèdent un axe commun de rotation.
