Quantum Fuel Systems Technologies Worldwide Inc, a leader in natural gas, alternative fuel systems and clean propulsion vehicle technologies, announces that it has received official notification from the United States Patent and Trademark Office that the company has been issued a key patent covering pressure and flow management for on-board gaseous fuel storage systems.
This newly granted patent, US 8,322,357, claims, among other things, a bi-directional fuel system comprising a fuel storage tank, a regulator, a check valve between the storage tank and the fill line and configured to allow flow into the storage tank, and a distal pressure delayer having an inlet connected to the fill line and an outlet connected to the tank valve. The innovative pressure delayer provides important safety features to protect the various components during rapid natural gas refueling and consumption conditions.
"We continue to innovate and enhance our fully-integrated advanced natural gas fuel systems that incorporate our industry-leading Q-Lite ultra-lightweight storage tanks," says Brian Olson, president and chief executive officer of Quantum. "We have a strong and innovative record in system engineering and integration as demonstrated by successful launches of advanced natural gas vehicle production platforms."
Over the past 12 months Quantum has been granted a number of patents pertaining to pressurized fuel system and storage technology, adding to Quantum's portfolio of proprietary and protected technologies. Quantum's intellectual property portfolio includes in excess of 60 patents (issued and pending) related to natural gas and hydrogen storage and metering systems and refueling and hybrid electric drivetrain systems.
