Jet Edge, Inc. has announced that the United States Patent and Trademark Office has issued the waterjet manufacturer a patent for a high pressure fluid sealing mechanism designed by Jet Edge R&D Engineer Michael Wheeler. Jet Edge’s proprietary high pressure fluid sealing mechanism (U.S. Patent 8,333,387) improves waterjet seal life by providing robust Metal-on-Metal sealing without the use of conventional plastic seals. This technology uses two convex curved surfaces in single line contact with one another to seal ultra-high pressure (UHP) fluid at static pressures up to 130,000 psi.
