ENGINE ON, STEERING WHEEL NOT TURNED
The pressure oil produced by bile vane cells is led to the steering gear via the calibrated bore (9a) and also to the spring chamber behind the
volume control valve (30t) via the bore (9b).
The calibrated bores (9a, 9b) restrict the oil flow so that a lower oil pressure prevails in the spring chamber behind the volume control valve (30t)
than on the side of the high-pressure chamber. The volume control valve (30t) opens (Figure 1) and the surplus pressure oil flows back into the
reservoir.
