Abstract
A tray for de-aeration of oil contained in an oil pan including an inner surface, an outer surface, and a side surface. The inner surface is adapted to face a bottom surface of the oil pan. The outer surface is adapted to face an oil-gas interface of the oil contained in the oil pan. The side surface extends from the inner surface. Moreover, the side surface encloses a submerged surface to collect aeration bubbles present in the oil.
Claims20
A tray for de-aeration of oil contained in an oil pan, the tray comprising:
- an inner surface adapted to face a bottom surface of the oil pan;
- an outer surface adapted to face an oil-gas interface of the oil contained in the oil pan;
- and
- a side surface extending from the inner surface, the side surface encloses a submerged surface to collect aeration bubbles present in the oil.
A lubrication system for an engine comprising:
- an oil pan having a bottom surface;
- oil contained in the oil pan, the oil having a oil-gaseous interface;
- and
- a tray in the oil pan, the tray including:
- an inner surface adapted to face a bottom surface of the oil pan;
- an outer surface adapted to face an oil-gas interface of the oil contained in the oil pan;
- and
- a side surface extending from the inner surface, the side surface encloses a submerged surface to collect aeration bubbles present in the oil.
A method for de-aeration of oil contained in an oil pan, the method comprising:
- providing a submerged surface to collect aeration bubbles present in the oil;
- merging of the collected aeration bubbles to form larger aeration bubbles on the submerged surface;
- moving of the larger aeration bubbles towards an oil-gaseous interface;
- and
- bursting of the larger aeration bubbles at the oil-gaseous interface.
The method of claim 20, wherein the bursted larger aeration bubbles are vented above the oil-gaseous interface.
