Energy -saving hydraulic pump

The utility model discloses an energy -saving hydraulic pump, including the pump case, press glossy way, the parallel key, the oil absorption oil circuit, the inlet port, the rotor, a stator, the hydraulic pressure pump shaft, the blade, the blade oil groove, press the hydraulic fluid port, a pump cover, the blade hydraulic fluid port, independent gear pump, check valve and flow control valve, through all installing flow control valve at inlet port and the oil feed end of pressing glossy way, the velocity of flow that can control the oil absorption oil circuit and press the oil in the glossy way, thereby reduce to change the pressure that the pipeline that leads to received because of the velocity of flow, and then reduced the pipeline and taken place by the condition that the extrusion leads to damaging, and the flow on the glossy way of regulating press as required, thereby the pressure on glossy way is pressed in control, can put forward the efficiency of voltol oil, and then the work efficiency of hydraul
