Hydraulic Steering Racks
The main rack shaft in a Hydraulic powered steering rack has a piston attached, and the pinion of a hydraulic steering rack has a control valve built around it. When the pinion valve is turned, it controls the fluid that is supplied by the power steering pump and directs the fluid to a piston attached to the main rack shaft, at this point the fluid forces against the piston to give the steering assistance. A hydraulic steering rack requires feed from either a hydraulic or electric hydraulic power steering pump.
