Beneficial effects of the present invention are：During present invention work, pressure oil enters to oil distribution casing through oil inlet, while motor drives
Dynamic transmission shaft rotates, and transmission shaft, which rotates, drives cylinder body to rotate, so as to which the in vivo plunger of cylinder be driven to be rotated simultaneously on the end face waved
It moves axially under the action of waving, so as to smoothly complete oil suction and oil extraction, is born when oil outlet pressure rise reaches motor
When carrying torque, the pressure oil of oil outlet has promoted Variable Control spool to move up between the second oil circuit and the 3rd oil circuit so that
First oil circuit is opened, and the second oil circuit and the 3rd oil circuit is separated, and pressure oil has entered Variable Control through the first oil circuit at this time
Valve chamber, the pressure oil for playing variable control valve intracavitary are installed again through the second oil circuit into the first mounting hole and the second mounting hole, first
Pressure oil in hole promotes adjusting apparatus to move forward, and the pressure oil in the second mounting hole promotes variable device to move forward, by
Forced area between adjusting apparatus and pressure oil is more than the forced area between variable device and pressure oil so that adjustment dress
It puts the power for acting on and waving and acts on the power waved more than variable device, and then promote swinging rotary, swinging rotary promotes
Flow mandril compresses the first spring and is moved to flow mandril direction, and gradient is waved in reduction, and then reduces plunger axial movement
Distance reduces the output displacement of oil outlet so that output power is always lower than the input torque of motor, when the pressure oil of oil outlet
Flow is close to minimum discharge, and when the pressure oil pressure of oil outlet is close to maximum pressure, pressure oil promotes cone blocking to move up at this time,
5th oil circuit is opened, and the pressure oil of oil outlet enters pressure-regulating valve chamber through the 5th oil circuit, and the hydraulic oil of pressure-regulating valve chamber is again
Enter oil inlet through the 4th oil circuit so that output power is always lower than the input torque of motor, when the present invention is stopped, rises
Variable Control spool resets under the action of Variable Control spring is played, and it is multiple under the action of pressure-adjusting spring that pressure adjusts cone blocking
Position, the pressure oil in the first mounting hole and the second mounting hole has flowed into variable control valve intracavitary through the second oil circuit at this time, plays variable
The pressure oil of control valve intracavitary is again through in the 3rd oil circuit feed pressure adjustment valve chamber, and the pressure oil of pressure-regulating valve intracavitary is again through the
Four oil circuits flow into oil inlet, and the first spring promotes flow mandril to reset at this time, so as to drive swing reset.The present invention makes output work
Rate is always lower than motor input torque, until output displacement is more than in oil pump until leakage 1%, so as to fulfill input small-power
The efficient purpose of large-displacement energy-saving is exported, it is more energy saving than ordinary high pressure oil pump to reach more than 40%；Small flow output during high pressure,
So as to reduce oil liquid temperature, ensure that fluid never degenerates, fluid usage time reaches 5 times of common oil pump or more；Oil pump is from pressure
