<p>This hydraulic injector (2) of a Pelton turbine comprises a nozzle (4), centered on a central injection axis (Y2), a sleeve (8), which is arranged coaxially in the interior of the nozzle, and a needle (10), which is movably mounted in relation to the sleeve along the central injection axis. The needle (10) is pivotable in relation to the sleeve (8) about the central axis (Y2) between a first position, in which it is axially secured to the sleeve, and a second position, in which it may be disengaged axially from the sleeve.</p> |
