BRAKE AND HYDRAULIC FAN SYSTEM - CONTINUED
When swashplate is at maximum angle, piston assemblies move in and out of cylinder barrel. Movement of piston
assemblies allows maximum amount of oil to be drawn into cylinder barrel. Pump produces maximum displace-
Swashplate angle is controlled by actuator piston. Actuator piston movement is regulated by oil pressure from
pressure and flow compensator valve.
