Covers Gaseous Fuel System, Innovative Pressure Delayer
Quantum Fuel Systems Technologies is talking up a “key” patent covering pressure and flow management for onboard gaseous fuel storage systems. Quantum (NASDAQ:QTWW) has been emphasizing not just lightweight Type fuel cylinders but the systems for putting them to work in vehicles.
The newly granted patent, U.S. 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,” Quantum says.
“The innovative pressure delayer provides important safety features to protect the various components during rapid natural gas refueling and consumption conditions,” the company adds.
Quantum says that its intellectual property portfolio now includes more than 60 issued and pending patents related to natural gas and hydrogen storage and metering systems and fueling, and to hybrid electric drivetrains.
“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,” Quantum president and CEO Brian Olson said in a release. “We have a strong and innovative record in system engineering and integration as demonstrated by successful launches of advanced natural gas vehicle production platforms.”
Quantum says that its natural gas storage systems “provide dramatic weight reduction, increased fuel storage capacity, and the capability to quickly integrate.”
Quantum last month reported a $2.5 million order for its CNG systems from Greenkraft (F&F, January 8), as well as purchase orders from new and existing customers worth some $600,000 for its Q-Lite brand CNG fuel cylinders for light-duty vehicles.
