Abstract: A method for opening tank shut-off valves in a fuel cell system that includes multiple pressurized tanks. A flow control device is positioned in a supply line downstream of the tank shut-off valves. When the system is started up, only one of the tank shut-off valves is opened to allow the pressure in the supply line to increase between the tank shut-off valves and the flow control device before the other tank shut-off valves are opened. Therefore, only one of the tank shut-off valves is subjected to the high pressure difference that induces significant valve wear and tear. The valve opening sequence is controlled so each of the tank shut-off valves is selected as the one to be opened at system start-up by a cycling process.

Abstract: A gas line (120) for supplying hydrogen gas and a harness (110) for supplying power to an electromagnetic valve are connected to an electromagnetic valve mechanism (200). The length of the harness (110) from a connecting member (111) to a fastener (160) is denoted by the letter “n” and the length of the gas line (120) from a connecting member (121) to a fastener (170) is denoted by the letter “m” (n<m). During a vehicle collision, a hydrogen gas tank (100) moves, placing tension on the harness (110) and the gas line (120). The tension causes both the harness (110) and the gas line (120) to stretch. The limit value of the stretch amount of the harness (110), which is shorter between the connecting member and the fastener, is low such that the harness (110) will break before the gas line (120) is damaged. As a result, power to the electromagnetic valve mechanism (200) is cut off and the electromagnetic valve closes before the gas line (120) is damaged, thus preventing a gas leak.

Abstract: A flow setting assembly is provided to permit field adjustment of an electronically actuated flow control valve, particularly a pressure independent characterized control valve (PICCV). In a preferred form, flow can be field adjusted by using a hex tool. Therefore, the maximum flow can be increased or decreased within the valve's adjustable flow range. As with all high close-off valves that employ a ball in their design, the ball passes well into the seat when rotated to the actuator's zero-degree position. Therefore, there is an amount of travel within the first degrees of ball rotation that passes back over this seat. The flow setting assembly eliminates this excess rotation (12°) resulting in a closed position that is offset to improve control resolution and system accuracy. This offset continues to allow the high close-off rating of 200 PSI. MFT actuators electronically adjust to and maintain the 2-10 Volt control signal at the reduced angle, as well as the 100 second running time and feedback signal.
