水車。 In a Pelton water turbine equipped with a needle that is driven by an electric servo motor through a coupling mechanism and that opens and closes the opening of the jet pipe to adjust the flow rate of pressurized water to the runner, a piston that is directly connected to this needle through a needle stem. A needle shock absorber is provided, which consists of a cylinder that slidably accommodates this piston and is filled with an incompressible fluid, and a throttle valve that connects the chambers on both sides partitioned by the piston of this cylinder. The Pelton water wheel is characterized by its
