  • High-pressure gas cylinder valve for vehicle
    Patent number: 11953153
    Abstract: A high-pressure gas cylinder valve for vehicle includes a valve seat having a gas charging runner and a gas supplying runner. A check valve is connected in series onto the gas charging runner, and the check valve and a solenoid valve are connected in series sequentially onto the gas supplying runner in a gas flow direction. A portion of the gas supplying runner located downstream of the solenoid valve is jointly connected to a portion of the gas charging runner adjacent to a gas inlet end and supplies gas to outside through a gas inlet of the gas charging runner when the gas supplying runner supplies gas. The gas cylinder valve further includes a flow-blocking buffer structure connected in series onto the gas supplying runner and located downstream of the solenoid valve and upstream of an intersection of the gas supplying runner and the gas charging runner.
