Engine pre-lubricating system

A pre-starting lubrication system to be used on an engine having an oil reserve, wherein engine lubricating oil is contained, and an engine internal oil pressure system structured to distribute lubricating oil to wearing parts of the engine from the oil reserve, said pre-starting lubrication system comprising;

• an oil reservoir structured to contain a quantity of engine oil therein,
• said oil reservoir including an air flow corridor wherethrough air enters and exits said oil reservoir, and an oil flow corridor, wherethrough oil enters and exits said oil reservoir,
• said oil flow corridor being connected in fluid flow communication with the engine internal oil pressure system by an oil conduit,
• said air flow corridor being connected in fluid flow communication with air supply means by an air conduit, said air supply means being structured to selectively supply a quantity of air under pressure,
• air venting means structured and disposed to selectively permit air from venting out of said oil reservoir,
• oil supply means structured to supply said quantity of engine oil into said oil reservoir,
• switching means structured to initiate and maintain air flow from said air supply means through said air flow corridor and into said oil reservoir so as to push oil out of said oil reservoir, through said oil flow corridor, and into the engine internal oil pressure system, through said oil conduit, for pre-starting lubrication distribution of the oil to the wearing parts of the engine,
• level maintenance means structured to prevent overfilling or total emptying of said oil reservoir, and accordingly preventing the oil from exiting said reservoir through said air flow corridor and the air from exiting, said reservoir through said oil flow corridor,
• said air flow corridor being disposed in a top surface of said reservoir and said oil flow corridor being disposed in a bottom surface of said reservoir,
• said level maintenance means including a stopper float disposed in said reservoir so as to float on the oil contained therein,
• said stopper float being structured to seal off said air flow corridor upon an oil level in said reservoir rising to a reservoir full level, and to seal off said oil flow corridor upon said oil level in said reservoir dropping to a reservoir empty level,
• said reservoir further including a tapered upper surface which tapers inwardly to said air flow corridor so as to guide said stopper float into its flow sealing orientation over said air flow corridor, and
• said reservoir including a tapered lower surface which tapers inwardly to said oil flow corridor so as to guide said stopper float into its flow sealing orientation over said oil flow corridor.
