Power Steering Flush in Santa Clara
What is Power Steering?
Power steering enables easier turning operation in recirculating-ball steering
systems. One system attributes about 80% of the steering force to the
hydraulic power assist and only 20% to the driver. This is accomplished
through a variety of pumps and valves. If contaminants develop and build
up in the system, proper operation of components such as the rotary valve,
spool valve, inner and outer valves in the torsion bar, and the pressure
relief valve can be affected.
The rotary vane pump is the component containing the reservoir for
the power steering fluid. The engine’s belt drives the pump, which
pulls fluid from the return line at low pressure and forces it into a
high pressure line. The high pressure outlet hose is connected to
spool valve assembly.
The spool valve assembly controls the direction of the hydraulic power
assist, whether it assists a left or right hand turn. When the tires are
oriented straight ahead, both hydraulic lines contain the same amount
of pressure to the steering gear. But high pressure fluid is applied
in one of the lines as soon as the spool valve is turned one way or the
other by the steering wheel. This high pressure assist provides the
80% of turning force we previously mentioned.
