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.

An oil circulation system of an internal combustion engine comprises a first oil pan and second oil pan, first oil supplied parts supplied with oil stored in the first oil pan, second oil supplied parts supplied with oil stored in the second oil pan, and a heating part. The heating part has oil paths through which oil flows and heats the oil flowing through the oil paths. The oil circulation system comprises a first circulation path circulating oil through the first oil pan, heating part, and first oil supplied parts, and a second circulation path circulating oil between the second oil pan and the second oil supplied parts.

There is provided an internal combustion engine in which oil can be kept in an oil passageway when oil is supplied, so that the time required to supply oil can be reduced. In an internal combustion engine in which an oil supply inlet for replenishing, with oil, an oil pan reservoir chamber disposed in a lower portion of a crankcase extends obliquely downwardly from an oil supply port at an upper end thereof, the oil pan reservoir chamber has an oil pan inlet port disposed in a position offset from a vertical plane, including the oblique oil supply inlet, and a horizontal oil supply passageway bent and extending substantially horizontally from a lower end of the oil supply inlet is connected to the oil pan inlet port.

An oil pan may include a pan body forming a dual chamber including a primary chamber and a secondary chamber, and a mesh. The primary chamber and the secondary chamber each contains a different amount of oil, and the mesh allows a different amount of oil permeation discharged from the secondary chamber to the primary chamber based on temperature of the oil.

An internal combustion engine includes: a crankshaft; a crankcase that supports the crankshaft; an oil tank that is at least partially partitioned by the crankcase; a scavenge pump including a first intake port and a first discharge port; a feed pump including a pump shaft, a second intake port and a second discharge port, oil that has been sucked in through the second intake port as the pump shaft rotates being discharged through the second discharge port; a scavenge discharge passageway connecting the first discharge port of the scavenge pump to the oil tank; and a feed intake passageway connecting the oil tank to the second intake port of the feed pump. As viewed from the axial direction of the pump shaft, at least a portion of the feed pump and the oil tank overlap each other.

The oil pan assembly includes an oil pan and a slideable cover. The oil pan includes a base and a sidewall which surrounds the base wherein the base and the sidewall are configured to retain a pool of oil. The oil pan further includes a peripheral flange operatively configured to be coupled to an engine block. The slideable cover is affixed to the oil pan and is configured to maintain the pool of oil proximate to the base of the oil pan.

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.

An oil tank (100) for a gas turbine engine is provided. The oil tank (100) comprises an oil inlet (102), an oil outlet (104), and a body including a coiled portion (106) interposed between the oil inlet (102) and the oil outlet (104). Oil is received by the coiled portion (106). The coiled portion (106) acts to at least partially de-aerate oil received from the oil inlet (104).

An oil tank system (100) for a gas turbine engine is provided. The oil tank system (100) includes an oil tank (102) having an upper tank portion (112) and a lower tank portion (114), a waisted section (118) being provided between the upper tank portion (112) and the lower tank portion (114). Oil is received by a de-aerator (104) of the system (100) which supplies de-aerated oil to the upper tank portion (112). The waisted section (118) includes an upper face (119) configured to catch oil drips from above the waisted section (118) and to guide oil to a lower face (121) of the waisted section (118).
