Filed:

Jul 30, 2009

Appl. No.:

12/512874

Inventors:

Casparus Jan Hendrik Seyffert - Solvang CA, US
Andrey D. Atanassov - Sarasota FL, US

Assignee:

Cobra North America, LLC - Centennial CO

International Classification:

B24C 5/02

US Classification:

451 90, 451 40

Abstract:

A fluid jet assembly includes a non-pressurized lance barrel through which a high pressure hose (“a lance hose”) is threaded and anchored at the distal end of the lance barrel relative to an operator's position. The other end of the lance hose is coupled to a high pressure fluid source. The fluid is fed into the lance hose and transported to the output of the lance barrel, where it is discharged as a fluid jet stream. A nozzle is mounted at the output of the lance barrel to control the characteristics of the fluid jet flowing out of the lance hose. When infused with an abrasive material, the fluid jet stream exits the nozzle in a focused jet capable of cutting through most structural surfaces.

Appl. No.:

12/512910

Inventors:

Casparus Jan Hendrik Seyffert - Solvang CA, US
Andrey D. Atanassov - Sarasota FL, US

International Classification:

B24C 5/00

US Classification:

451 38, 451 90, 451 91, 451101, 451 40

Abstract:

A fluid jet system providing a hydraulic induction manifold for at least two valves. The manifold is positioned “upstream” of an abrasives holding tank, so that no abrasive material flows through the valves and the manifold. The valves and the manifold provide pressurized fluid for at least two different flows: (1) a primary fluid flow and (2) an abrasive material flow through the abrasives holding tank. The two flows are merged again at a junction to provide a fluid flow having a predetermined abrasive-to-fluid mixture ratio. The manifold balances the pressure of the two different flows using a preset geometric relationship between the two different output flow paths associated with the valves.
