Accusump Selection Help
2qt (4 pint) Accusump, part code 24-026. The Accusump, the original automotive oil accumulator, is designed to provide the engine with oil pressure before the starter is even engaged. An Accusump is a cylinder shaped aluminum storage container that acts as a reservoir of pressurised oil, to be released when there is a drop in the oil pressure. The Accusump is connected to the pressure side of an engine's oiling system and is charged by the engines own oil pump. Its simple, efficient design revolves around a hydraulic piston separating an air pre-charge side and the oil reservoir side.
On the oil side of the Accusump it has an outlet that goes into the engine's oiling system, controlled by a valve. On the air side it's equipped with a pressure gauge and a Schrader air pre-load valve.
How does an Accusump work?
On initial start-up when the valve on the oil side is opened the pressurized oil is released into the engine and therefore pre-lubricating the engine prior to start-up. The Accusump holds whatever oil pressure the engine has at the time that it is shut off. After the engine is started and the oil pump has taken over, oil is pumped back into the Accusump. This moves the piston back and pressurises the Accusump until it equalises with engine's oil pressure.
While driving, if the engine's oil pressure is interrupted for any reason, the Accusump releases its oil reserve again, keeping the engine lubricated until the engine's oil pressure comes back to normal. This release of oil could last from 15 to 60 seconds, depending on the size and speed of the engine.
In racing or hard driving conditions, the Accusump will automatically fill and discharge when needed as you corner, accelerate and brake.
Measures 4.25" (108mm) diameter by 12" (305mm) long excluding pressure gauge and relief valve. This is 4 US Pints capacity (2 US Fl.Quart) which is approximately 1.9 litres.
Selecting the proper valve for the Accusump is essential to proper oil control. There are 3 types of valves that we recommend. The first and most basic is our manual ball valve, which is recommended for pre-oiling applications that have easy access to the Accusump. Second would be our electric valve without the EPC switch, which is typically recommended for pre-oiling applications where the Accusump is not in an easy to reach location or where ease of use is a priority. For track use we almost always recommend using an electric valve with an EPC Switch. This valve type will guarantee that the Accusump is as full as it can be when you hit the part of the track that causes oil pressure problems.
