In the full hydrostatic power steering, the steering controller is connected to the steering cylinder with only the
hydraulic piping. Accordingly, it does not have mechanical transmitting parts such as steering gear, pitman arm, drag
link, etc
.. Therefore, it is simple in construction. This steering system consists of the oil strainer (6), hydraulic pump
(5), flow priority valve (3), steering controller (1), steering cylinder (2), etc
..
Flow priority valve (3) which located in the hydraulic control valve assembly (4) divides the oil into two direction.
One is the control flow to power steering (constantly 8.0 Llmin.,
2.1 U.S.gals.lmin., 1.8 Imp.gals.lmin.), and the other
is excessive flow to control valve
of implement lift control.
By operating the power steering body, the required amount
of oil is fed to the steering cylinder (2).
