Abstract
A tool for cutting up coke in containers. The tool includes a housing mounted on a drill stem in the operating condition. The tool also includes at least one cutting nozzle for cutting and a boring nozzle for boring coke by means of a water jet, and a switching apparatus for controlling the feeding of pressurized water flowing through the drill stem and the housing. The switching apparatus includes a linearly moveable switching element, a driving apparatus and a control apparatus, which is rotatable as a function of a change of the water pressure by the driving apparatus to switch a valve to distribute the water and to pass it on. The angular position of the control apparatus controls whether the flow path of the water to the boring nozzle or the flow path to the cutting nozzle is free or obstructed.
