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.

摘要： A compressor adapted for capacity control includes a rotor mounting thereon vanes slidably, a cylinder receiving therein the rotor and the vanes, side plates secured to the opposite sides of the cylinder, a vane chamber defined by the vane, rotor and the cylinder and closed at its sides by the side plates, suction ports and a discharge port. Suction loss produced when the pressure within the vane chamber becomes below the pressure of the refrigerant supply source during a suction stroke is utilized for suppressing the refrigerating capacity of the compressor at high speed operation. With the arrangement of the compressor, the effective area of the flow passage leading to the vane chamber from the suction ports varies in at least two stages such that it becomes smaller in the latter half of the suction stroke than in the former half thereof. Thus, in the compressor, driving torque can be reduced at low speed operation and adequate effects of capacity control can be obtained at high speed operation.
摘要翻译：适用于容量控制的压缩机包括：转子，其上可滑动地安装有叶片，其中容纳转子和叶片的气缸，固定到气缸相对侧的侧板，由叶片，转子和气缸限定的叶片室，其侧面由侧板，吸入口和排出口组成。当在吸入行程期间使叶片室内的压力变得低于制冷剂供给源的压力时产生的吸入损失用于抑制高速运转时的压缩机的制冷能力。利用压缩机的布置，从吸入口导向叶片室的流动通道的有效面积至少在两个阶段变化，使得在吸入冲程的后半部分中比其前半部分变小。因此，在压缩机中，在低速运转时可以降低驱动转矩，能够在高速运转时获得充分的容量控制效果。
