Abstract:
A lubrication system includes a rotary pump, an eductor, and a solenoid valve and is configured to provide pressurized oil to an engine. The rotary pump is configured to generate oil flow. A supplemental supply line selectively provides pressurized oil into the eductor. The solenoid valve is movable between a first position and a second position. The solenoid valve supplies a fluid signal that allows pressurized oil to flow from the supplemental supply line and into the eductor when the solenoid valve is in the first position to increase the volume of oil flowing from a sump of the engine into the rotary pump. When the solenoid valve does not supply a fluid signal, pressurized oil is prevented from entering the eductor and the volume of oil flowing from the sump and through the eductor to the rotary pump is not increased.
