Abstract
A hydraulic system for feeding an action turbine comprising a rectilinear gate and an injector mounted in series on a conduit through which water is supplied to the turbine wherein the gate has a shut-off which is mounted in an outer body member for the injector, said shut-off having a seat member associated therewith, the injector including a needle valve which has a seat member associated therewith, said seats being located adjacent one another. The needle valve may have a support associated therewith and the shut-off for the gate may be located upstream thereof. The needle valve seat may be displaceable downstream to permit closing of the gate. In such position, the needle vale and its seat may be disassembled without emptying the water supply conduit.
