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 .
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. Butterfly valve, for flow regulation in large pipe diameters. Clapper valve, Used in appliances like the Siamese fire appliance to allow only 1 hose … 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
