る可変容量形ポンプの回転速度制御装置。 a variable displacement pump driven by a drive source whose driving speed increases or decreases depending on the weight and weight of the load; an input means for setting and inputting a target rotational speed of the variable displacement pump by mechanical displacement; and the variable displacement pump. a hydraulic signal line for converting the actual rotation speed of the pump into a hydraulic pressure signal; and a direction for internally converting the hydraulic pressure signal into mechanical displacement and comparing this with the mechanical displacement given by the input means to cancel the difference. and a servo mechanism for changing the operating displacement of the variable displacement pump, the variable displacement pump being always rotated at the set input value. Speed control device.
