Claims

[Scope of utility model registration request]

The drive-side main shaft and the pump-side hollow shaft are connected by a coupling having a space inside, and a transmission gear is rotatably supported on the outer periphery of one of the two shafts with its center axis coincident. , this transmission gear is rotationally driven by an external power mechanism,
an idler having gears at both ends and rotatably supported through the coupling so that the gear at one end meshes with the transmission gear and the gear at the other end is introduced into the coupling;
In the blade angle control device for a movable blade-shaped fluid machine, the drive mechanism for driving the blade angle control shaft inserted into the hollow shaft by the rotation of the idler is accommodated in the coupling. A differential gear device is interposed between either the drive side main shaft or the pump side hollow shaft,
The rotation shaft of the power mechanism is connected to the input shaft of the differential gear, and the transmission gear and either the drive side main shaft or the pump side aerial shaft are connected to both output shafts of the differential gear device.
A blade angle operating device for a movable blade type fluid machine characterized by the following.
