ACCUSUMPT OIL ACCUMULATORS

An Accusump is an oil reservoir that is connected to the engine's oiling system. It is designed to deliver pressurized oil to an engine before starting to eliminate dry star scuffing (pre-oiling) and to discharge its reservoir of oil during low oil pressure surges to protect against engine damage during demanding racing conditions.

It installs simply with only one oil line connecting it. Through this line the Accusump fills and discharges. This oil line may be plumbed into the return line of an oil cooler or remote filter using a "T" fitting, into an oil input sandwich adapter, or directly into one of the engines oil galleys.

The Accusump's design includes a piston. On one side of this piston is pressurized air and on the other side of the piston is the reserve of oil. To hold this reserve of oil in the Accusump when the engine is not running and there is no oil pressure to hold it, a valve must be installed on the oil line. The three different valve options for the Accusump are the manual ball valve for pre-oiling and surge control, electric valve for pre-oiling operation , and the EPC (electric pressure control) valve for pre-oiling and surge control. Before the engine is started the operator should open the manual valve or turn on the toggle switch or ignition switch to activate the electric valve or the EPC valve. The opened or activated valve releases the reserve of oil that is under pressure in the Accusump. This released oil will go tot the engine's bearings to pre-oil the engine for a non-scuff start. After the engine is running and the oil pump builds pressure, oil is pumped back into the Accusump for the next restart or whenever the engine's normal oil pressure is interrupted. The Accusump will automatically charge and discharge as needed to maintain oil pressure during hard cornering , acceleration and braking.
