Square pump for cab lifting belongs to the field of auto parts. The purpose of the utility model is to adopt one-way oil feeding square pump for cab lifting through the improvement of the
oil feeding system, no matter rising or falling. The valve body of the oil storage device is inserted with an oil circuit reversing valve. On the hydraulic directional valve to open one inlet, the
no. 2 oil inlet, oil outlet no. 1 and no. 2 oil outlet, one of the inlet, the no. 2 oil inlet can respectively with that of the oil inside the seat, and one inlet and one oil outlet in the hydraulic directional
valve are interlinked, no.1 oil outlet corresponding rose oil, no. 2 oil inlet with the no. 2 oil outlet in the hydraulic directional valve are interlinked, no. 2 oil outlet corresponding falling oil; The front
end of the oil circuit directional valve is open with a finite slot, and the limiting screw is inserted in the limiting slot; The oil inlet is communicated with the oil circuit through the oil reservoir, and the
lower end of the oil circuit is provided with a pressure regulating valve body. The utility model has the advantages of reasonable structure, convenient installation, and reduced volume.
The upward and downward oil routes are adopted for one-way oil feeding, and the pressure of the system is reduced, so that the oil leakage phenomenon is not easy to occur.
