Abstract: Disclosed is a dual-purpose faucet comprising a faucet pipe, a ball valve for gradually blocking and unblocking the faucet pipe at the free end thereof, and a fountain check valve extending through the upper surface of the faucet pipe from within the faucet pipe. When a fluid is being discharged from the faucet pipe, and, at which point, as the control means is operated so as to block the faucet pipe, the backpressure created as a result thereof, upon reaching a threshold pressure, causes the fountain check valve to open allowing the fluid to pass therethrough resulting in the discharge of a fluid jet therefrom; the trajectory of the fluid jet adjustable by adjusting the control means as adjusting the control means regulates the backpressure.

Abstract: A mode shifting apparatus for a decoking tool. 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. The diversion plate may be temporarily unseated from an adjacent surface of the mode shifting apparatus prior to relative rotation between them such that both rotationally-induced forces and the need for relying upon a lubricating fluid to achieve damping between adjacent component surfaces may be reduced.
