THEORY OF OPERATION - CONTINUED
BRAKE AND HYDRAULIC FAN SYSTEM - CONTINUED
Pressure and flow compensator valve is mounted to pump and contains two spools. Flow compensator spool regu-
lates pump output flow in response to load sensing port.
Pressure and flow compensator valve correct pressure and oil flow. Pump flow and pressure are maintained by
either sending pump oil to actuator piston or by draining pump oil from actuator piston.
Actuator piston and bias spring work together to adjust swashplate angle. Pressure and flow compensator valve
prevents pump overloading.
