摘要

The engine (1) has an upper cylindrical case (20) surrounding cylinder barrels (21), whose axes are oriented horizontally. A lower oil sump (30) defines a crank chamber (37) and a reserve chamber (43), and comprises a base wall (31) for receiving lubrication liquid e.g. oil, from a lubrication circuit. The reserve chamber has a lower cover (40), in the form of a plate, placed opposite to the base wall such that the base wall forms a part of an upper wall of the reserve chamber. A back stop device (38) is associated to orifices (34) of the base wall.
