  • Patent number: 11739856
    Abstract: A valve for a hydrogen tank of a fuel cell vehicle includes a first open hole for communicating with a tank-side flow passage, a blocking body for blocking the tank-side flow passage, and a second open hole that allows the tank-side flow passage to communicate with a pipe-side flow passage formed at a pilot plunger. As the pilot plunger ascends in the state in which the first open hole communicates with the tank-side flow passage, the tank-side flow passage is blocked by the blocking body and subsequently communicates with the pipe-side flow passage via the second open hole, thereby reducing the size of a section in which a pressure difference occurs between the flow passages and reducing the time taken to eliminate the pressure difference, thus securing stable supply of hydrogen from a hydrogen tank to a fuel cell.
