10.1.3 Steering Hydraulic System Major Components
Engine driven rotary vane pump (belt driven 12 cylinder; direct drive from timing gear 6 cylinder) with falling
flow characteristic (as
pump speed increases fluid flow decreases) and integral pressure relief valve.
Remote fluid reservoir with integral 'return' side filter.
Steering rack (incorporating speed sensitive transducer).
Steering control module
(SCM).
Fluid cooler integral with engine coolant radiator and associated pipe-work.
10.1.4 Hydraulic System Features
The 'Servotronic' system reduces steering input loads during parking and low speed manoeuvres and progressively
increases input loads as vehicle speed rises. This feature enhances steering feel.
10.1.5
Rotary motion of the steering wheel is converted, via the steering gear pinion to lateral motion of the rack. Hydraulic
assistance is provided by pressurized fluid being directed against the rack bar piston in the rack cylinder. The pressure
applied to each side of the rack piston is controlled by the pinion valve which varies the restriction through which the
flow for each side of the rack piston must pass.
