ABSTRACT:
One end of an operating rod is connected to a deflector arm which causes a jet deflector of a Pelton wheel to open or close while the other end of the operating rod carries a spring bearing plate which is disposed in the bore of a cylinder which is movable in the axial direction of the operating rod. A spring is accommodated in the bore of the cylinder on the side of the operating rod. One end of the cylinder is pin connected to the midpoint between the ends of a swinging lever whose one end is pivotally supported and whose other end is connected to an electric servomotor so that upon energization of the servomotor, the swinging lever is caused to undergo a reciprocal angular motion. The deflector is forced to move to its full closure position by the release of the energy stored in the spring.
