Latest Patents

Among his latest patents, Hughes developed a crashworthy solenoid actuated valve for CNG powered vehicles. This bidirectional solenoid operated valve is designed to control the flow of compressed gas to and from a pressurized vessel. It features an automatic mechanism that blocks gas flow in the event of an electrical failure or crash, ensuring safety by preventing catastrophic failures. The valve includes a manual lockdown feature, an integral electrical pass-through assembly, and a thermally activatable pressure relief device.

Another significant patent is the refueling check valve for compressed natural gas powered vehicles. This assembly allows for rapid, efficient, and safe refueling. It consists of a receptacle that mates with a fuel supply nozzle and a valve body with two gas flow passages. The check valve within the first gas flow passage is normally closed to prevent gas flow but opens when fuel under pressure is applied, allowing gas to flow into the fuel storage vessel. Additionally, a by-pass valve is included for depressurizing the fuel system prior to servicing.
