Abstract
A preoiler and lubricating fluid reservoir for use primarily with an internal combustion engine is disclosed. A hollow cylindrical reservoir is provided with an internal slidable piston which divides the cylinder into a compressed air retaining section and a lubricating fluid retaining section. A solenoid controlled valve assembly, which is controlled by the vehicle's oil pressure sensor unit, regulates the flow of lubricating fluid either out of the reservoir either during start up of the engine or in instances of low oil pressure, and into the reservoir during periods of normal engine operation. The valve is structured to insure that oil flow out of the reservoir during preoiling is unrestricted but that refilling of the reservoir is accomplished only after the engine's oil pressure has come up to normal operating level. The system also serves to provide emergency oiling of the engine should the oil pump fail or a loss of oil pressure be encountered.
