An oil deflector for an internal combustion engine has first and second oil-deflecting plates between a crankshaft and an oil pan. In order to configure the overall space, and in particular the overall height, of an oil-deflecting device so that it is as small as possible, it is proposed to arrange the oil-deflecting plates such that they overlap at a distance apart over the length of the crankcase. The longitudinal edge of the second oil-deflecting plate forms a main oil scraper edge. Strip-shaped ribs are arranged between the oil-deflecting plates, in their overlapping region, for the purpose of guiding oil in the direction of a suction point of the oil pan. The first oil-deflecting plate has apertures in the region of the width of a respective crank assembly assigned thereto. These apertures serve as secondary oil scraper edges.
Oil deflector for an oil pan of an internal combustion engine, comprising a first oil deflecting plate and a second oil-deflecting plate between a crankshaft and an oil pan, the oil-deflecting plates overlapping and forming a channel in a region, wherein at least one longitudinal edge of the second oil-deflecting plate forms a main oil scraper edge, wherein, in the region, the oil-deflecting plates overlap and an arrangement is provided between the oil-deflecting plates to guide oil in a direction of a suction point formed in the oil pan, wherein the arrangement provided to guide oil is formed by strip-shaped ribs which extend essentially vertically between the first oil-deflecting plate and the second oil-deflecting plate, wherein the oil-deflecting plates are connected to the ribs and therefore form an oil-deflecting device which can be handled as a combined component, and wherein the ribs are aligned at an angle of approximately 35° with respect to the axial direction of the crankshaft and a longitudinal central axis of the oil-deflecting device, and the oil is directed by the ribs to the suction point.
