A pressure self-matching energy utilization system includes a synchronous motor (), a control valve (2), a working pump (3), an energy accumulator (4) and a pressure actuation element (5) and corresponding oil pipe connection. A main outlet (OUT) of the synchronous 5 motor is connected to a load keeping cavity of the pressure actuation element. A first inlet ONO of the synchronous motor is connected to an oil port of the energy accumulator via a first switch valve (K1) of the control valve. A second inlet (1N2) of the synchronous motor is connected to an output port of the working pump via a second switch valve (K2) of the control valve. The system can automatically match the output pressure of the working pump and the output 10 pressure of the energy accumulator based on the magnitude of external load, to achieve the purpose of fully using the pressure energy recycled in the energy accumulator. - 9 -
