Two oil cylinder oil inlets mouthful are equipped with, two switching valve oil-outs of hydraulic steering valve 3 pass through two of oil circuit and steering cylinder 4 respectively
Between oil cylinder oil inlet mouthful connection, and hydraulic steering valve 3 and each described switching valve oil-out and the oil cylinder oil inlet mouth of steering cylinder 4
A connection piece is mounted on, the switching valve oil-out of hydraulic steering valve 3 is entered by oil circuit and connector to the oil cylinder of steering cylinder 4
Hydraulic fluid port fuel feeding.On the one hand connector in such scheme serves the effect of connection oil circuit, has passage inside connector in addition, can
Oil transportation is carried out as oil circuit, do so can be convenient for changing part, meanwhile, oil circuit connection design is more reasonable.
It is furthermore preferred that being provided with least one tank drainback mouthful on hydraulic oil container 1, the switching valve on hydraulic steering valve 3 is returned
Hydraulic fluid port 13 is connected by oil circuit with the tank drainback mouthful on hydraulic oil container 1.The present invention devises tank drainback on hydraulic oil container 1
Mouth is to allow hydraulic oil to be partly refluxed to 1 two utilizations of hydraulic oil container, efficiently solving the energy, reduce cost.
Specifically, two tank drainbacks mouthful are provided with hydraulic oil container of the invention 1, respectively the first tank drainback mouthful 8
With the second tank drainback mouthful 9；
Wherein, the switching valve oil return opening 13 on hydraulic steering valve 3 is by the second tank drainback on oil circuit and hydraulic oil container 1
Mouth 9 is connected.
Meanwhile, the above-mentioned connector of the present invention uses three-way connection, two connectors to be respectively the He of the first three-way connection 22
Second three-way connection 5；
It is shown in Figure 2, wherein, it is respectively provided with oil inlet end 18, oil outlet end on the first three-way connection 22 and the second three-way connection 5
19 and oil revolving end 20, the oil inlet end 18, oil outlet end 19 be connected inside oil revolving end 20.External structure and common three joints
It is similar, all it is T-shaped structure, oil inlet end 18 is oppositely arranged to form a horizontal pipeline with oil outlet end 19, and oil revolving end 20 is perpendicular to entering
Oily end 18 and oil outlet end 19 are set, overall T-shaped structure.
But, the place that three-way connection of the invention is different from existing threeway is：Internal diameter, oil outlet end at oil inlet end 18
The internal diameter of position is 6mm between internal diameter and oil inlet end 18 and oil outlet end 19 at 19, and the internal diameter at the oil revolving end 20 is
