1. A kind of 1. multi-way valve system, it is characterised in that including banked direction control valves and the first oil pump, the second oil pump and fuel tank,The banked direction control valves includes valve core of multiway valve, the first one-way throttle valve and the second one-way throttle valve;

  • First one-way throttleValve, valve core of multiway valve and the second one-way throttle valve are sequentially communicated by oil circuit;

    First one-way throttle valve and the second unidirectional sectionOil circuit between stream valve can drive the valve core of multiway valve to move, so that the valve core of multiway valve controls the conjunction of the banked direction control valvesStream and shunting;

    Point to the valve core of multiway valve, second one-way throttle in the direction of the check valve of first one-way throttle valvePoint to the valve core of multiway valve in the direction of the individual event valve of valve;

    The banked direction control valves also includes the first reversal valve, first reversal valveThere are two opposite directions by oil communication, first reversal valve with second one-way throttle valve;

    Described first is singleConnected to choke valve, valve core of multiway valve, the second one-way throttle valve and the first reversal valve by circulating oil path;

    First oil pump and the second oil pump oil suction from the fuel tank, first oil pump and the second oil pump with it is described moreBy oil communication, the valve core of multiway valve can control in the banked direction control valves between first oil pump and the second oil pump road valveThe interflow of oil circuit and shunting;

    The multi-way valve system also includes the second reversal valve and the 3rd reversal valve;

    Second reversal valve pointIt can not sent out with first oil pump and the first reversal valve by oil communication, second reversal valve to first reversal valveDynamic signal oil sources, so that first reversal valve commutates;

    3rd reversal valve commutates with second oil pump and first respectivelyValve is by oil communication, and the 3rd reversal valve can start signal oil sources to first reversal valve, so that the banked direction control valvesValve element moves.
