Abstract
PURPOSE: To maintain pressure of an operating medium fed to a load at a constant, and to enable a plurality of compressors to run under equal load and equal ratio, by using a microcomputer to perform pressure control and load allotment control.
CONSTITUTION: A pressure value of medium discharged from compressors 1a, 1b, which is detected by a discharge pressure detector 5, and open-degrees of vanes 101a, 101b, which are detected by vane open-degree detectors 9a, 9b, are applied to an operation circuit 113 through an input circuit 111 of a microcomputer 11. By performing comparing operation, at each sampling time set on a data setting unit 12, to these applied value and a set value stored on a memory circuit 112 through the data setting unit 12, medium pressure fed to a load 3 is always maintained at a constant. Further, by controlling vane driving devices 8a, 8b through an output circuit 114, equal load running and equal ratio running of the compressors 1a, 1b can be carried out.
