装置。 A load limiting device that limits the turbine load of a geothermal power generation device having two gas extractors, and includes a cup valve having a compression spring and a motor that increases or decreases the amount of compression of the compression spring to adjust oil pressure. In this method, the diameter of the cup valve is reduced and the spring constant of the compression spring is increased to enable rapid changes in the steam regulating valve control oil pressure, and the motor is controlled in the decreasing direction by a trip signal of one of the gas extractors. 1. A load limiting device comprising an additional circuit for rotating the load to a desired value.
