Abstract

An oil container of a combustion engine. Oil collected in the oil container can be, conveyed to the combustion engine and back into the oil container, having a central oil chamber out of which oil can be suctioned and lateral oil chambers positioned either obliquely above or obliquely below the central oil chamber depending on an oblique position of the oil container. Oil is directed to the lateral oil chambers from the combustion engine, and, depending on the oblique position of the oil container, the central oil chamber can be coupled to a first lateral oil chamber that is adjacent to the central oil chamber on a first side of the central oil chamber, or to a second lateral oil chamber that is adjacent to the central oil chamber on a second side of the central oil chamber, via a respective passively controlled check valve.

First claim

The invention claimed is:

1. 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.

2. The oil reservoir according to claim 1 , wherein at least one of the first and second check valve is oil pressure-controlled.

3. The oil reservoir according to claim 1 , wherein at least one of the first and second check valve is gravity-controlled.

4. The oil reservoir according to claim 1 , wherein the central oil chamber is closed at a top.

5. The oil reservoir according to claim 1 , wherein each of the at least two lateral oil chambers is subdivided into multiple part oil chambers.

6. The oil reservoir according to claim 1 , wherein the respective inner lateral part oil chamber of the respective lateral oil chamber can be coupled to the central oil chamber via at least one of the respective check valves, which are each passively controlled.

7. The oil reservoir according to claim 6 , wherein the respective inner lateral part oil chamber of the respective lateral oil chamber is closed at the top.

8. The oil reservoir according to claim 1 , wherein at least the respective outer lateral part oil chamber of the respective lateral oil chamber, which is located the furthest away from the central oil chamber, is open at the top.

9. The oil reservoir according to claim 1 , wherein the internal combustion engine, is an internal combustion engine installed on a ship.

10. The oil reservoir according to claim 1 , wherein the first and second check valve are normally half open.
