Engine pre-oiler

Claim 1

A pre-oiler system for pressurizing lubricant within machinery prior to normal operation of the machinery lubrication system, said pre-oiler system comprising, an oil vessel containing lubricant under pressure, said vessel including a base, means selectively communicating the oil vessel interior with a lubrication passageway of the machinery, said means remotely actuated upon closure of an electrical circuit preparatory to starting of the machinery, and a valve assembly regulating lubricant flow between said vessel and said selectively communicating means and including a spring biased movable valve body having a first position whereat a restricted return flow of lubricant may enter said vessel during normal operation of the machinery lubrication system to gradually charge said vessel while adequate machinery lubrication system pressure is maintained, said valve body having a second position permitting an oppositely directed outward flow of lubricant from said vessel for machinery lubrication at a greater rate than the first position flow rate of said valve body, said movable valve body having multiple ports therein some of which are closed in said first position while other of said ports at all times remaining open.
