Abstract
A fluid reservoir for providing a supply of a lubricating fluid for an internal combustion engine, specifically for use in marine environments. The reservoir includes a housing for containing and protecting, a ventless flexible liner for housing a supply of fluid, where the flexible liner is located within the housing, and an orifice and conduit that extends through the ventless flexible liner and the housing for permitting the introduction of fluid into the ventless flexible liner and for permitting the removal of fluid therefrom. The fluid reservoir is constructed and arranged such that the ventless flexible liner is in a generally collapsed state until a fluid is introduced therein through the orifice. The introduction of fluid into the ventless flexible liner through the orifice expands the ventless flexible liner, while the removal of fluid from the ventless flexible liner collapses the ventless flexible liner proportionally as the 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.
