Hydraulic power steering Is an auxiliary system that uses the #engine #power to change the angle of the wheel axis and thus change the direction of the #car by the hydraulic pressure provided by a hydraulic pump driven by the vehicle’s engine .
valves are used to control liquids and gases movements and to adjust its flow and pressure . It has many types due its function Ball #valve , for on/off control without pressure drop, and ideal for quick shut-off, since a 90° turn offers complete shut-off angle, compared to multiple turns required on most manual valves. … Read more
#Hydraulic #pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome #pressure induced by the load at the pump outlet.
There is a multiple designs for the hydraulic pump
the #gear hydraulic pump is a simple effective design and cheap
