摘要： A fluid rotating apparatus of a positive displacement pump includes a plurality of rotors accommodated in a housing, a bearing for rotatably supporting the rotors, a suction port and a discharge port formed in the housing, a suction chamber and a discharge chamber in the housing respectively communicating with the suction port and the discharge port, a plurality of motors for individually rotating the rotors, and a detecting device for detecting rotating angles and rotating numbers of the motors. In the apparatus, a fluid is sucked and discharged due to capacity change of a space defined by the rotors and the housing through synchronous control of the rotation of the plurality of motors by a signal from the detecting device. The housing has a communicating path with a flow control device to make an upstream side communicate with a downstream side of the apparatus when the rotational numbers of the rotors are less than a predetermined value. A method of controlling the apparatus includes the steps of opening the communicating path by operating the flow control device to cause the upstream side to communicate with the downstream side of the apparatus when the rotational numbers of the rotors are less than a predetermined value, and closing the communicating path by operating the flow control device when the rotational numbers of the rotors are not less than a predetermined value.
