1. a kind of hydraulic system, which is characterized in that including:

  • Fuel tank accommodates hydraulic oil;

    First oil cylinder and the second oil cylinder;

    Control valve group, the outlet of entrance and unidirectional oil pump, outlet are connected to first oil cylinder and the second oil cylinder;

    Intermediate, the outlet of the entrance of the intermediate and the control valve group, the outlet of the intermediate and first oilCylinder and the connection of the second oil cylinder;

    The intermediate includes main body, and it is logical that first passage, second channel and third are formed in the main bodyRoad;

    The entrance of the first passage, the second channel and third channel outlet with the control valve group respectively;

    Described firstThe outlet in channel is connected to the first oil pocket A '"'"' of the first oil pocket A of first oil cylinder and second oil cylinder respectively;

    It is describedThe outlet of second channel is connected to the second oil pocket B of first oil cylinder;

    The outlet of the third channel and the of the second oil cylinderTwo oil pocket B '"'"' connections;

    Unidirectional oil pump is connected to by entrance with the fuel tank, is connected to first oil cylinder and the second oil cylinder by exporting;

    InstituteIt states unidirectional oil pump and hydraulic oil is transferred to the first oil cylinder and/or second from the fuel tank through the control valve group and the intermediateOil cylinder, so that first oil cylinder and/or the second oil cylinder can relatively move;

    When the unidirectional oil pump is to the first oil pocket A fuel feeding, first oil cylinder is moved to first direction, when to described theWhen two oil pocket B fuel feeding, first oil cylinder is moved to the second direction opposite with the first direction;

    When the unidirectional oil pump is to when to the first oil pocket A '"'"' fuel feeding, second oil cylinder is moved to first direction, when toWhen the second oil pocket B '"'"' fuel feeding, second oil cylinder is moved to the second direction opposite with the first direction;

    And the first direction of first oil cylinder is opposite with the first direction of the second oil cylinder.
