the rotary meter and is directed out the L port. Pressure retracts the steering
cylinder for a left turn. The rotary meter ensures that the oil flow to the cylinder is

the steering cylinder flows back through the spool valve, then out the T port of
the steering valve and returns to the hydraulic tank. When the steering wheel
reaches the end of its rotation, the relief valve in the steering valve opens and
directs the hydraulic flow out the steering valve T port to the oil cooler until the
steering wheel is released.
