2. Or Proposed simplified hydraulic schematic (one generator)
2 Circulation pumps
1 Suction pump Or
2 Circulation pumps
Air compressor

3. Hydraulic system functionality Oil distribution RESERVOIR
Main switch
Dump switch
Oil exits the pump and goes the 3-way valve
Passes through the Oil filter and heat exchanger
Distributes to the generators
Returns from generators
Circulates

4. Hydraulic system functionality Oil distribution GENERATORS
Oil flows to the inlet valve
Passes through the valve to the switch
Heats up in the generator
Returns to the reservoir
Same for all switches
Main switch
Dump switch

5. Hydraulic system functionality Bypassing Main switchX
Open bypass valve and close inlet valve
Oil circulation in switch stopped X
Close switch outlet valve
