Patent ID: 11904435

Abstract:
A water-abrasive suspension cutting facility includes a high-pressure source (3) for providing (301) water at a high pressure, a high-pressure conduit (5) which is connected to the high-pressure source (3), a pressure tank for providing (303) a water-abrasive agent suspension (13) which is at a high pressure, a lock chamber (21) which is designed to temporarily be at a high pressure and temporarily at a low pressure, and a filling valve (23) for filling (311) the lock chamber when this is at a low pressure. A pump (31) at the suction side is fluid-connected to the lock chamber in a manner capable of being shut off, in a manner such that given high pressure in the lock chamber (21) the pump is shut off from this and given low pressure in the lock chamber (21) the pump is in the position of sucking an abrasive agent suspension through the filling valve (23) into the lock chamber (21).
