Abstract
PURPOSE: To provide an energy-saving electrohydraulic servo tester by inserting into an end portion of an oil tank a shielding plate having a row of small bores so as to form an auxiliary tank for use in accumulating therein return oil from a relief valve, and controlling a swash plate of a variable oil pump in accordance with the oil level in the auxiliary oil tank.
CONSTITUTION: A shielding plate 11 is inserted in an end portion of an oil tank 6 to form an auxiliary tank 12 for accumulating return oil Q2 from a relief valve 5. The shielding plate 11 is provided with a row of small bores or slits to average the dynamic fluctuations of the flow rate Q2 occuring due to the vibrations of the oil Q1 flowing to an oil pump. The oil level in the auxiliary oil tank 12 is measured by an oil gauge 16. A motor for setting the angle of a swash plate of a variable oil pump 2 is controlled in accordance with a measured oil level in the tank 12 so that the flow rate Q2 can be regulated to an optimum level.
