翼流体機械。[Claims for Utility Model Registration] (1) A blade angle operating shaft is provided within the rotating shaft so as to be movable in the axial direction, and movement of the blade angle operating shaft allows the movable blade provided at the tip of the rotating shaft to be moved. In a movable blade fluid machine that adjusts an angle, an annular interlocking member that moves in the axial direction in conjunction with the blade angle operating shaft is disposed outside the rotating shaft, and an output signal is generated by the axial movement of the annular interlocking member. A plurality of non-contact type position detectors that change are arranged at positions equally divided on a concentric circle, and the output signals of the plurality of non-contact type position detectors are given to an arithmetic unit to calculate the sum of the output signals. The blade angle control shaft is configured to generate a corresponding calculation output signal, apply this calculation output signal to a low-pass filter, and control the movement of the blade angle operation axis based on the output signal of the low-pass filter and the setting signal output from the blade angle setting device. A movable wing fluid machine characterized by: (2) The low-pass filter is an integrator, and a comparison amplifier compares the signal smoothed and output by this integrator with the setting signal output from the blade angle setting device. The four-way switching valve is switched and controlled by the comparison output signal, and the four-way switching valve controls pressure oil introduced into a servo cylinder that moves the blade angle operating shaft in the axial direction, thereby servo controlling the blade angle operating shaft. A movable blade fluid machine according to claim 1, characterized in that the movable blade fluid machine is configured to do so.
