Title: RING GATE FOR A HYDRAULIC MACHINE AND METHOD FOR CLOSING
Abstract:
The invention relates to a ring gate for interrupting the water flow through the water path of a hydraulic machine having a rotor and having a spiral, comprising a first hollow body (1), which extends around the rotor axis and which is designed in such a way that said first body can be moved from an open position to a closed position and back, wherein no water flow through the hydraulic machine can occur when the first body (1) is in the closed position, wherein the ring gate comprises a second hollow body, which extends around the rotor axis and which is designed in such a way that said second body can be moved from a first position outside of the water path to a second position within the water path and back in the axial direction, wherein the second body (2) has openings in the wall of the second body, through which openings water can flow when the second body (2) is in the second position and the first body (1) is not in the closed position.
