| description | The invention relates to the technical field of aloft working cars and particularly discloses a power switching valve. The power switching valve comprises two pump-connecting oil ports, four working oil ports and a pair of hydraulic-control reversing valves which are correspondingly connected with the two pump-connecting oil ports; an oil inlet (3), a first oil outlet (2), a second oil outlet (4), and a control oil port (1) which controls the oil inlet (3) to be connected with or disconnected from the first oil outlet (2) or the second oil outlet (4) are formed in each hydraulic-control reversing valve; the oil inlets (3) of the hydraulic-control reversing valves correspondingly communicate with the two pump-connecting oil ports, and the control oil ports (1) of the hydraulic-control reversing valves communicate with an external connecting port; a hydraulic system with the power switching valve comprises a hydraulic executing component, an engine and a closed type pump driven by the engine; and the closed typ |
