Oil container of a combustion engine

An oil reservoir of an internal combustion engine, oil that is collected in the oil reservoir and can be removed from the oil reservoir for at least one of lubrication and cooling of the internal combustion engine and delivered in a direction of the internal combustion engine and subsequently returned from the internal combustion engine into the oil reservoir, the oil reservoir and comprising:

• a central oil chamber defined by at least a first wall and a second wall, from which the oil can be suctioned and delivered in the direction of the internal combustion engine;
• at least two lateral oil chambers, which dependent on an inclined position of the oil reservoir, are positioned either obliquely above or alternatively obliquely below the central oil chamber, wherein the oil, emanating from the internal combustion engine, is returned into the at least two lateral oil chambers,
• at least one first passively controlled check valve arranged in the first wall and configured to couple a first lateral oil chamber, which adjoins the central oil chamber on a first side of the central oil chamber, to the central oil chamber dependent on the inclined position of the oil reservoir;
• and
• at least one second passively controlled check valve arranged in the second wall and configured to couple a second lateral oil chamber, which adjoins the central oil chamber on a second side of the central oil chamber opposite the first side, to the central oil chamber dependent on the inclined position of the oil reservoir,
• wherein each of the first and second lateral oil chambers is subdivided into an inner lateral part oil chamber and at least one outer lateral part oil chamber, and
• wherein the part oil chambers adjoining one another are coupled via separating walls that are permanently open with oil-permeable recesses.
