Abstract
A device includes a fluid jetting tube, a cylinder and a disk valve. The cylinder is formed on an exterior of the fluid jetting tube and includes a port to receive a fluid supply line and an internal movable piston configured to control an internal volume of the cylinder. The disk valve rotates within the cylinder and extends from the internal volume of the cylinder through a slot in the fluid jetting tube into an interior of the fluid jetting tube.
Claims22
A device, comprising:
- a fluid jetting tube;
- a cylinder formed on an exterior of the fluid jetting tube, the cylinder including a port to receive a fluid supply line and a piston configured to control an internal volume of the cylinder;
- and
- a disk valve configured to rotate within at least a portion of the cylinder, wherein the disk valve extends from within the internal volume of the cylinder through a slot in the fluid jetting tube into an interior of the fluid jetting tube.

A method, comprising:
- adjusting a fluid supply rate and fluid pressure to a cylinder of a device, wherein a nozzle of a jetting tube of the device is connected to a duct having a cable inserted within;
- adjusting a position of a piston within the cylinder of the device to adjust a volume of the cylinder;
- adjusting a spinning rate of a disk valve contained within the device to set a fluid jetting impulse frequency;
- monitoring movement of the cable within the duct;
- and
- determining, based on the monitored movement of the cable, whether the fluid pressure, cylinder fluid volume and fluid jetting impulse frequency achieves a vibratory resonance condition within the duct.
3 more elements
A fluid jetting device, comprising:
- a tube;
- a cylinder formed on an exterior of the tube and having an internal volume;
- and
- a valve shaped as a disk and configured to rotate within the cylinder, wherein the disk extends from the internal volume of the cylinder through a slot in the tube into an interior of the tube.
