1. active hydraulic energy storage device loop, it contains hydraulic power supply (1), safety valve (2), position control valve I (4), hydraulic accumulator (6), pressure transducer (10) and bi-bit bi-pass electrically-controlled valve I, II, III (3,5,11), it is characterized in that having set up oil hydraulic pump (7), motor (8), motor speed controller (9), the hydraulic fluid port C of the hydraulic fluid port A of oil hydraulic pump (7) and bi-bit bi-pass electrically-controlled valve III (11) is by the filler opening x of hydraulic tubing L1 and hydraulic accumulator (6) InBe communicated with;

  • The hydraulic fluid port D of the hydraulic fluid port B of oil hydraulic pump (7) and bi-bit bi-pass electrically-controlled valve III (11) is communicated to the hydraulic fluid port E of position control valve I (4) and the hydraulic fluid port G of bi-bit bi-pass electrically-controlled valve I (3) by hydraulic tubing L2;

    The hydraulic fluid port F of position control valve I (4) is communicated to the oil outlet P of hydraulic power supply (1) by pipeline L3;

    The hydraulic fluid port H of bi-bit bi-pass electrically-controlled valve I (3) is communicated to the rodless cavity C1 of oil hydraulic cylinder I (16) by pipeline L4;

    Motor (8) drives oil hydraulic pump (7) through shaft joint (12) and rotates, and motor speed controller (9) connects control motor (8);

    Pressure transducer (10) is installed in the import x of hydraulic accumulator (6) InThe place, described oil hydraulic pump (7) is that twocouese or folk prescription are to the oil hydraulic pump that rotates.
