(35) Main Hydraulic Oil TankIn the hold position, proportional relief valve (PRV) (19) and (PRV) (23) are de-energized. Ejector control spool (22) remains centered. Oil flow from steering and ejector pump (1) and fan, brake, and ejector pump (2) is blocked from flowing to ejector cylinder (26).Pilot oil supply to the PRV's is provided by fan, brake, and ejector pump (2) via pilot pressure reducing valve (13) installed in combination valve (8). The pilot pressure reducing valve reduces the high-pressure supply oil to pilot pressure. The valve is also designed to drain pilot pressure to the main hydraulic oil tank (28) when the engine is shutdown.Without signal from brake control (11) or ejector control valve (18) to flow compensator spool (7) of the fan, brake, and ejector pump, the pump remains in the standby condition. However, in the scenario above, there is a light signal from steering system (16) being transmitted through steering signal resolver (14) to flow compensator spool (5) of the steering and ejector pump. this signal causes the pump to upstroke and maintain margin pressure above the signal pressure. Backflow check valve (15) prevents the higher pressure from the steering and ejector pump from blending with the oil in the fan, brake, and ejector pump circuit. Relief valve (20) and relief valve (24) protect the ejector system components from excessive high pressures when the ejector is in the full extend or retract position.Ejector Control - Eject Position

(35) Main Hydraulic Oil TankIn the Eject condition, the transmission ECM sends a PWM signal to ENERGIZE eject proportional relief valve (PRV) (19). This action allows pilot pressure oil to move ejector control spool (22) to the ejector eject position. The combined oil supply from the steering and ejector pump (1) and fan, brake, and ejector pump (2) flows
