5.3.2 Work principle
Valve bore, valve sleeve, valve body in the redirector makes up of along valve,
having an effect of controlling the direction of the oil flow. Rotor and stator makes up of
cycloid mesh, having an effect of measure element when turning, to make sure that
the oil quantity in oil crock and corner of steering wheel makes direct ratio; having an
effect of hand moving oil pump when turning by manpower; and linkage shaft having
an effect of transferring wrest rules.
Middle position (steering wheel isn’t running), in the opening ring system, the oil
from oil pump passes through the lumen of valve bore to oil box. (Fig.5.3 a)
When turning by power, oil from oil pump pass through the along valve to cycloid
pin wheel mesh, force rotor running following steering wheel, and press the ration oil
to the left or the right of crock, force turning wheel to turn by power, and oil in the other
cylinder flows back to oil box. (Fig.5.3 b, c)
When engine comes out flameout, the steering wheel will be operated by
manpower, with valve bore,
melt, interlock shaft, driving
rotor to press oil in one
cylinder to the other one,
then force turning wheel, to
carry out turning by
manpower (Fig.5.3 d). Filling
oil by oil box when passing
through filling unilateralism
valve.
