Abstract:
There is provided a hydraulic system, including an oil tank storing operating oil, a hydraulic actuator, and a hydraulic pump which draws the operating oil from the oil tank and supplies the operating oil to the hydraulic actuator. The hydraulic system is provided with an operating oil separating unit which is located at a midway point of a main tube sending the operating oil from the hydraulic pump to the hydraulic actuator and which separates a part of the operating oil supplied from the hydraulic pump to return the part of the operating oil to the oil tank. A universal testing machine including the hydraulic system is also provided.
