【発明の名称】圧縮天然ガスを燃料とする車両用の燃料補給用逆止弁組立体
Document Type and Number:
Japanese Patent JP2677541
Kind Code:
B2
Abstract:
A refueling check valve assembly which provides for rapid, efficient, and safe refueling of compressed natural gas powered vehicles is provided and includes a receptacle adapted to mate with a fuel supply nozzle and a valve body having first and second gas flow passages therethrough. The respective first ends of the first and second gas flow passages communicate with the receptacle, while the respective second ends of the first and second gas flow passages are adapted to communicate with a fuel storage vessel, typically through a fuel supply line. A check valve is positioned in the first gas flow passage of the valve body and is normally biased into a closed position to prevent the flow of gas through the first gas flow passage. The check valve opens in response to a flow of fuel under pressure, permitting the flow of gas to the fuel storage vessel. A by-pass valve is also provided in the second gas flow passage in the valve body for depressurizing the fuel system prior to servicing.
