CONSTITUTION: A hydraulic device(100) comprises a motor(120), a rotary shaft(130), a pumping cam(140), a pump(150), a first flow path, a second flow path, a first switch valve(160), a first switch valve cam(170), a third flow path, a fourth flow path, a second switch valve(180), and a second switch valve cam(190). The pumping cam is coupled to the rotary shaft and rotates with the rotary shaft. The pump is operated by the pumping cam and pumps oil from an oil tank. The first flow path connects the first space of a hydraulic cylinder to the pump. |
