FILTER ELEMENT AS-AIR 1N4864 - Caterpillar

The BrakeSaver permits the operator to control the speed reduction of the vehicle on grades and curves. The BrakeSaver permits the operator to control the speed reduction at any time when speed reduction is necessary but long applications of the service brakes are not desired.The crankshaft is turned by the rear wheels through the differential, the drive shaft, the transmission, and the clutch. This is during a downhill operation. The speed of the vehicle can be reduced when a braking force is applied to the crankshaft. The braking force is attained when the BrakeSaver converts the energy of rotation into heat. The heat is removed by the engine cooling system.BrakeSaver Components

BrakeSaver Components (1) Flywheel housing. (2) Rotor. (3) BrakeSaver housing. (4) Flywheel. (5) Crankshaft flange. (6) Ring gear plate. (7) Stator.The BrakeSaver housing (3) is fastened directly to the rear face of the flywheel housing (1). The BrakeSaver adds approximately four inches to the length of the engine drive train. A rotor (2) and a ring gear plate (6) are installed between the rear flange of the crankshaft (5) and the flywheel (4). The engine can use a standard starter motor with the ring gear plate (6). The rotor turns in a space between the stator (7) and BrakeSaver housing (3).

BrakeSaver Components (8) The rear section of the oil pump. (9) BrakeSaver. (10) Tube. (11) Hole. (12) Bypass valve. (13) Baffle. (14) The front section of the oil pump. (15) Engine Oil pan. (16) BrakeSaver control valve. (17) Line. (18) Line.The engine oil pump has two sections. The front section (14) of the oil pump gives oil to the engine for lubrication. The rear section (8) of the oil pump sends engine oil through the BrakeSaver control valve (16) to the BrakeSaver (9). The rear section of the oil pump also sends oil through line (17) to the engine oil cooler (not shown). From the oil cooler, the cool oil goes through line (18), through baffle (13) and back into the engine oil pan (15) .The tube (10) allows the oil in the BrakeSaver to rapidly go out of the BrakeSaver when the BrakeSaver is turned off. This oil returns to the engine oil pan.The oil has a high viscosity when the engine is cold (starting conditions). The high viscosity causes a restriction to the oil flow through the oil cooler. A restriction in the oil cooler will result in an oil pressure difference in the bypass valve (12). The oil pressure difference will cause the valve to open. An open bypass valve will cause the oil from the rear section of the oil pump to go through hole (11) in the bypass valve (12). The oil drains back into the engine oil pan (15) .BrakeSaver Lubrication
