Abstract
A fluid reservoir assembly for providing a supply of a lubricating fluid for an internal combustion engine, specifically for use in marine environments. The assembly includes an outer shell for containing and protecting the assembly, a ventless flexible liner for housing a supply of lubricating fluid, where the flexible liner is located within the outer shell, and an orifice and conduit that extends through the ventless flexible liner and the shell for permitting the introduction of lubricating fluid into the ventless flexible liner and for permitting the removal of lubricating fluid therefrom. The fluid reservoir assembly is constructed and arranged such that the ventless flexible liner is in a generally collapsed state until a lubricating fluid is introduced therein through the orifice. The introduction of lubricating fluid into the ventless flexible liner through the orifice expands the ventless flexible liner, while the removal of lubricating fluid from the ventless flexible liner collapses the ventless flexible liner proportionally as the lubricating fluid is removed and delivered to the engine. The present invention eliminates the need for a vent, thus eliminating the problems associated with the prior art vented fluid reservoirs.
