The oil tank is sucked through the filter screen and be inhaled pump oil ,through the petroleum pipeline of oil pump transport to oil valve,When the hand wheel to send off the oil, due to the role of oil will push the piston, the oil from the return pipe to tank, when the hand wheel to open get the oil, then the working fluid into the fuel tank through the tubing, pressure tubing through and through oil return valve to tank.
Spatial Adjustment Method:
Through the hand wheel rotation, the adjustment of space to achieve compression.
Hydraulic System:
