Abstract: Multiport valve with outlets transverse to the inlet useful as a coker switch valve. A sealed lower sleeve assembly provides semi-trunnion ball support. An upper part of the outlet seat recesses is formed in the bonnet, and a lower part in the valve body, which together bias a resilient member to load the seats, independently of end connections. Before bonnet assembly, when the ball is rotated to face a body outlet, there is sufficient space in the seat recesses to insert the seat, slide the seat onto the ball, and then insert the resilient member. When all the seats and resilient members are in place, engagement of the bonnet biases the upper part of the resilient members to load the seat. In valve operation, an enlarged ball outlet bore can straddle two outlet ports and maintain process media flow during switching. Also, methods of assembling, operating, and servicing the valve.

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.
