HYDRAULIC STARTING SYSTEM - ANCHOR WINCH COMPARTMENT (Cont)
a. The Hydraulic Starting System (Figure 1-70) consists of a reservoir, an engine-driven charging pump
mounted on the anchor winch engine, and a hand pump with pressure gauge. It also consists of two piston-type
accumulators with pressure gauges, a starting motor, high and low pressure filters, and connecting hoses and fittings.
b. Hydraulic fluid flows by gravity or slight vacuum from the reservoir to engine-driven pump inlets or the hand
pump inlet. The hand pump supplies the initial charge or recharges the system. The fluid is discharged from the pump
outlet at a high pressure and flows into the accumulator. There it is stored at 3250 psi (228497.8 gm sq cm) under the
pressure of compressed nitrogen gas. When the starter is engaged and the control valve is opened, the expanding
nitrogen gas forces the fluid out of the accumulator at a high pressure. It then flows into the starting motor which quickly
speeds up the engine to a high cranking speed. The fluid returns from the starter to the reservoir.
