If the oil in your engine sloshes away from the sump pickup under cornering, acceleration, or braking, the pump will stop feeding pressurized oil to the bearings. Even momentary losses of oil pressure can quickly damage an engine.
An Accusump is a hydraulic pressure accumulator that protects your engine from temporary oil pressure loss. The precision-machined cylinder is divided into an oil chamber and a pressurized air chamber, with a free-sliding piston between. When the oil system builds pressure, oil is pushed into the cylinder, moving the piston and compressing the air. The air acts as a spring, pushing back against the piston and keeping the oil under pressure. Whenever the pressure in the oil system drops below the pressure stored in the cylinder, oil is forced out of the cylinder and back into the system to feed the bearings until the oil pump starts pumping again.
This 3-quart Accusump cylinder measures 4 1/4" OD x 16" Long (less gauge and valves). The oil chamber end has a 1/2" NPT female port for the oil control valve (sold separately) and an oil pressure relief valve installed in a 1/8" NPT female port. The air chamber end has an air pressure fill valve installed in a 1/8" NPT female port and an air pressure gauge installed in a 1/4" NPT female port (the gauge can be removed and remote-mounted if desired). Cylinder only -- control valve and mounting clamps are not included.
