Claim 9:
10. A method for water-abrasive suspension cutting, the method comprising the steps:
providing water at a high pressure in a high-pressure conduit by a high-pressure source;
providing an abrasive agent suspension, the abrasive agent suspension being at a high pressure in a pressure tank;
cutting a material by a high-pressure jet amid removal of the abrasive agent suspension from the pressure tank, the high-pressure jet at least partly comprising the abrasive agent suspension;
filling a lock chamber, which is at a low pressure, with abrasive agent amid at least temporal sucking of the abrasive agent suspension into the lock chamber by a pump, the pump being configured to be shut off from the lock chamber;
shutting off the pump from the lock chamber;
pressurizing the lock chamber to a high pressure; and
refilling the pressure tank with the abrasive agent from the lock chamber, which is at the high pressure, into the pressure tank.
