摘要

The engine has a casing reservoir delimited by a casing wall and containing a lubricant, where the wall has an orifice sealed by a pressure regulator. The regulator has chambers (21, 22) separated by a separation wall and disposed respectively in the upper and lower parts of the regulator. The chamber (22) is conformed such that a blow-by gas circulates in the chamber (22) in a circular manner when air is passed into the chamber (22).
