High pressure fluid jet cutting and drilling apparatus |
摘要 |
A high pressure fluid jet drilling system operable to produce the same drilling effect as a rotating nozzle, but without utilizing a high pressure rotary seal or coupling. The drilling effect is obtained by mounting a non-rotating drilling nozzle within a rotatable case eccentrically with respect to the axis of rotation of the case.
