In a not shell its an air over oil accumulator..
the cyl has a small adjustable air charge in the unit and it is plumed to the oil supply side on the other.
As oil is pumped to the engine it will also pump three qts to the accusump, which in turn will stay in reserve and supply the engine with oil if the oil pressure drops.
The oil pump pushes oil and so does the accusump on the other end with you engine in the middle if oil pressure drops from the oil pump the accusump will discharge oil in to the oil system to keep up oil pressure until the oil pump can catch up.
While the key is on the accusump has an open valve, so when you turn the key off the electric solinoid closes the valve trapping pressurised oil in the accusump so the next time you turn the key on... oil rushes back in to the engine and you no longer have a dry start...
i use them on my road race cars for high g turn when the oil runs away from the pick up, they also work great for 4x4's.
