A bleed valve, with a big recirculating low pressure line. Like the pressure regulator return for the fuel injection system.
I'll take a look in the diagram for the P/S system in my factory manual when I get home, I'm pretty sure that the rack only requires fluid flow when you are changing steer angle though, not just to hold at a steered angle. There are some valves, and passages, and bleeds, and....
Well mine has always worked, so I haven't had to mess with it, so I'm not 100% how it works! About the only thing on the C900 I don't know for sure how it works....
Best,
Drew
