High-pressure fluid apparatus used to disintegrate solid materials has drill head at least partially enclosed by shield when drill head is removed from container

摘要

The high-pressure apparatus comprises a drill stem (242) with a drill head (244) delivering a high-pressure fluid jet. A shield (246) is movably coupled to the device, wherein the drill head is at least partially enclosed by the shield when the drill head is removed from the container. The drill head delivers a second high-pressure fluid jet and is configured to bore a channel into a solid phase. An independent claim is also included for a method for shielding a high-pressure device.
