section 15 Fittings & Valves Moroso Accumulators, Fittings & Valves These provide an instantaneous supply of oil when pressure falls below a safe level. Our professional series are available in 1.5 or 3.0 quart versions. The 1.5 quart version is perfect for Sport Compacts and other vehicles with 4 and 6 cylinder engines. Ideal for street performance and mild off-road applications. All Accumulators store oil under pressure and automatically release that oil to the main galleries when oil pressure drops. Moroso Accumulators can also be used to manually pre-lube engines before starting to prevent cold-start scuffi ng and premature bearing wear. • Accumulators Protect Against Oil Pressure Loss! • Automatic Operation! HOW AN ACCUMULATOR WORKS The Accumulator is tapped to the pressure side of the engine’s oiling system. When the engine is running, oil pressure forces oil into the accumulator and compresses air ahead of it. Figure 1: Under normal conditions, oil pressure keeps a reserve of oil in the Accumulator under constant pressure. If oil pressure should suddenly drop because of hard acceleration, severe cornering or hard braking, air pressure immediately sends oil back into the engine. When the danger is over and the pump is once again supplied with oil, pressure in the engine forces oil back into the Accumulator where it is ready for the next emergency. Figure 2: When oil pressure drops, air pressure sends the stored oil into the engine at the main oil galleries to prevent damage. Three quarts of oil under pressure provide emergency supply instantaneously when needed. Air Pressure gauge verifi es that Accumulator is ready for use. Cold start valve releases oil into cold engine for reduced wear. Tapped for 1/2" NPT fi tting. Can be mounted in any position using Moroso Accumulator Mount. OIL ACCUMULATORS PART NO.

DESCRIPTION MOR23900-210 Replacement Gauge MOR97530 O Ring Kit 12 VOLT SOLENOID VALVE ACCUMULATOR FITTINGS Allows remote control of fl uid fl ow via 12v switch. Each side of the solenoid valve contains a 1/2” NPT female port. Solenoid Valve is open when toggle switch is on, when switched off remains closed regardless of ignition switch position. Use the toggle switch and 16 gauge wire included in the kit to wire the valve. A 20-amp fuse must be used between the power source and the switch. Use a power source that is active (i.e., “hot”) only when the ignition switch is in the “on” position. CAUTION!: Do not use with any fuels. We have a full range of fi ttings available, these are the most commonly used for an accumulator set-up. PART NO. DESCRIPTION MOR23905 Solenoid Valve, 1/2” NPT Ports SYDNEY 02 9838 7272 PART NO.

Once engine is running you will notice a pressure increase on the gauge. The system is now primed and ready to go. 155
