ABSTRACT:
The invention described includes a detent arrangement which, subject to fluid pressure which is a function of road speed, engages and therefore varies the elastically effective length of the known torsion bar which controls the power-assistance valve of a power-assisted vehicle steering system, so as to vary the extent of power assistance from a maximum at no or low vehicle speed to a minimum at an increased speed.
