Abstract

The invention discloses a system and a method for delivering cryogenic fluid. The cryogenic fluid delivery system includes a vessel containing a cryogenic fluid at a first pressure and a first temperature, a first heat exchanger coupled to the vessel for receiving the cryogenic fluid and cooling the cryogenic fluid to a second temperature, a first pump coupled to the first heat exchanger for pressurizing the cryogenic fluid to a second pressure, a second pump for pressurizing the cryogenic fluid to a third pressure, a second heat exchanger coupled to the second pump for cooling the cryogenic fluid to a third temperature, and a nozzle coupled to the second heat exchanger for delivering a jet of the cryogenic fluid toward a target.

Description

[0001] This application is a divisional application of a patent application with an application date of July 8, 2005, an application number of 200580029752.X, and an invention title of "System and Method for Transporting Cryogenic Fluid". technical field [0002] The present invention relates generally to fluid power machining and, more particularly, to systems and methods for conveying cryogenic fluids. Background technique [0003] In hydrodynamic machining, forces due to changes in momentum of a fluid stream are used to cut, grind or otherwise process material. For example, water is often used as a fluid to cut or grind certain materials, and various abrasive materials can be used to enhance material removal. However, water jet machining may suffer from problems related to the accumulation of water during the machining operation or to potential contamination of the surrounding environment or water by material removed from the workpiece. [0004] In order to solve the afo...
