Moroso Heavy Duty Accumulator, 3 quart capacity, 23" x 4-3/4" cylinder

The Accumulator is tapped to the pressure side of the engines oiling system. When the engine is running, oil pressure forces reserve oil into the accumulator and compresses the air ahead of it.

If oil pressure should suddenly drop because of hard acceleration, severe cornering or hard braking, the air pressure immediately sends oil to the main galleries. When the danger is over and the pump is once again primed with oil, the oil pressure forces oil back into the Accumulator where it is ready for the next emergency.

Oil accumulators are oil storage tanks, connected into the engine s oiling system that have pressurized air on one side, and engine oil on the other side of a movable piston.
When engine pressure fluctuates due to oil surging away from the pickup during hard acceleration, severe cornering or hard braking, a Moroso Accumulator equipped engine  provides an instantaneous supply of oil to the engine.

When the fluctuation is over and the oil pump is once again primed with oil, the engine s oil pressure forces this reserve of oil back into the Accumulator. When the engine returns to normal pressure, the Accumulator refills automatically, ready for the next possible occurrence.

Which Accumulator is best for my Application?

3-Quart capacity Moroso Accumulators are for V-8 and larger, high performance 6 cylinder applications

1.5-Quart capacity Accumulators are for 4 & 6 cylinders, applications where a 3-quart capacity with not fit and when the Accumulator s main function is to pre-oil the engine before start up

Moroso Accumulators require only one line which can be:

• "T-ed" into the return line of an oil cooler and/or remote oil filter
• Run through an Accumulator Adapter (page 152) that mounts between the engine s spin on oil filter and the engine, OR
• Run directly into a oil galley in the engine block that is on the pressure side of the engine s oiling system

Drag Racers have successfully used Moroso Accumulators to free up horsepower by running less oil in the oil pan

• For extreme applications €” specially designed caps withstand high pressure
• Smaller size allows installation in vehicles with limited space
• 3 quarts of oil under pressure provide emergency supply instantaneously when needed
• Air pressure gauge verifies that accumulator is ready for use
• Cold start valve releases oil into cold engine for reduced wear
• Tapped 1/2" NPT fitting
• Can be mounted in any position using Moroso Accumulator Mount No. 23921
• Includes a manual ball valve
