Title
(DE) ÖLABSCHEIDER
(EN) OIL SEPARATOR
(FR) SÉPARATEUR D'HUILE
Abstract
(EN) An oil separator includes a cylindrical separator body (70) and an inflow pipe (50) that introduces a fluid including an oil into the separator body (70) and that includes a curved portion (60). The curved portion (60) includes at least one oil draining hole (90).
(FR) L'invention concerne un séparateur d'huile pourvu d'un corps principal de séparateur cylindrique (70) et d'un tuyau d'entrée (50) qui introduit un fluide contenant de l'huile dans le corps principal de séparateur (70) et qui présente une portion courbe (60). Au moins un trou de vidange d'huile (90) est formé dans la portion courbe (60).
