friction between the tires and the road surface keeps the
ball nut (4) and sector shaft (6) in their positions. The
torsion bar (2) alone is twisted to produce a gap between
the input shaft (1) and sleeve (3) and to activate the
valve. By so doing, the cylinder's chamber "a" comes
under high pressure and the ball nut (4) is moved to the
right. Finally the sector shaft (6) gets turned to turn the
machine to the left.

input shaft (1) and sleeve (3) is in the direction opposite
to that of left turn. By so doing, the cylinder's chamber
"b" comes under high pressure and the ball nut (4) is
moved to the left. Finally the sector shaft (6) gets turned
to turn the machine to the right.
