the pilot valve rod operate. When the pilot
valve P opening is connected with CF opening,
the high-pressure oil flows to the steering
gear, passes through the valve element passage
in the steering gear, to the steering gear L
opening or R opening, and to the steering
cylinder. The big cavity of the left steering
cylinder is connected with the small cavity of
the right steering cylinder, and the small
cavity of the left steering cylinder is
connected with the large cavity of the right
steering cylinder. Both oil cylinders operate
jointly to drive the front wheels. When the
steering wheel moves slowly or does not operate,
most of the hydraulic oil from the steering

EF opening. The pilot valve T opening is
connected with the oil return opening of the
hydraulic oil tank. The steering gear has
following five oil openings: P, R, L, Ls and
T. P opening and Ls opening are connected with
corresponding openings of the pilot valve and
are not described again herein. When the
steering wheel rotates rightwards, R opening
