Abstract:
A mode shifting apparatus for a decoking tool is described herein. A diversion plate can be used to provide selective delivery of a pressurized decoking fluid to one or the other of nozzles in the tool. The mode shifting apparatus can be used to switch between a cutting mode of operation and a drilling mode of operation by rotation of the diversion plate, where a biasing force causes the diversion plate to unseat itself from an adjacent surface of the tool in order to reduce friction forces between them.
