Manual Extract: Pump oil amount and steering force

When there is plenty of oil flowing from the pump, the force needed to turn the steering wheel need only overcome the sliding resistance of the sleeve or rotor, so the steering wheel turns very smoothly.
* When the amount of oil from the pump is small, the displacement angle of the spool and sleeve reaches a maximum point; even if the hydraulic circuit is wide open, the flow of oil from the pump to the rotor is small, so the rotor turns slowly.
* For this reason, the spool rotates faster than the rotor, and the displacement angle reaches a maximum point, and the spool turns the rotor by means of the cross pin and drive shaft. At that time, the rotor works as.a hydraulic pump, and the steering wheel is harder to turn
