摘要： A pressure-reducing valve is disclosed which is capable of preventing leakage of a fluid from a passage aperture in a state in which the passage aperture is closed by a valve body. The pressure-reducing valve is structured such that a plunger is moved upward due to a biasing force of a shut spring when a magnetic field generated around and inside a solenoid body is released. Thus, the valve body is pushed up from below by a pressing portion of the plunger with a pressing force based on the biasing force of a shut spring. Due to the valve body being pushed up, the upper end of the valve body is placed in close contact with the inner peripheral portion of the passage aperture so that the passage aperture is closed. In this manner, leakage of hydrogen gas from a primary pressure chamber to a secondary pressure chamber (leakage of the gas pressure) can be prevented with certainty, and thus an unintentional increase of the pressure at the secondary pressure chamber side can be prevented with certainty.

摘要： A tank system of the invention with multiple tanks makes a joint flow of a fluid released from the multiple tanks and supplies the joint flow to a downstream device, which is located downstream of the multiple tanks. The tank system includes: primary pressure measurement modules that individually measure internal pressures of the multiple tanks as primary pressures; a secondary pressure measurement module that measures a pressure of the joint flow of the fluid as a secondary pressure; flow rate regulation modules that individually regulate release flow rates of the fluid to be released from the multiple tanks; and a pressure control module that estimates a supply flow rate to be supplied to the downstream device from the measured secondary pressure, and then sets an allocation of the supply flow rate of the fluid to be released from each of the multiple tanks corresponding to the measured primary pressure with regard to the tank. This arrangement ensures adequate regulation of the release flow rates from the multiple tanks.

摘要： There is disclosed a valve assembly for a gas container capable of appropriately discharging a gas from the gas container, even if a valve of a discharge passage has a failure or the like. The valve assembly for the gas container disposed at the gas container has, as passages which allow the inside of the gas container to communicate with the outside, a filling passage which fills the gas container with the gas and a discharge passage which discharges the gas. Furthermore, the valve assembly has a filling-side valve disposed at the filling passage and configured to close this passage, a discharge-side valve disposed at the discharge passage and configured to close this passage, a communication path which connects a downstream side of the discharge-side valve to a downstream side of the filling-side valve, and a shut-off valve disposed at the communication path. When the discharge-side valve does not open due to the failure or the like, the shut-off valve is opened to allow the gas to flow through the filling passage, the communication path and the discharge passage in this order.

摘要： Disclosed is a seal structure of a high-pressure tank capable of properly securing seal efficiency. The seal structure of the high-pressure tank includes a plurality of seal members that have mutually different seal properties and that are installed between a ferrule of the high-pressure tank and a valve body attached to the ferrule. One of the plurality of seal members has low temperature resistance, and the other has high temperature resistance. A first seal member is an O-ring formed of butyl rubber or silicone. A second seal member is an O-ring formed of EPDM. Furthermore, the two O-rings are different in gas permeability from each other. This seal structure can be applied between the ferrule and the valve body, in addition, between the ferrule and a liner, between the ferrule and a shell, and between the valve body and the shell.

摘要： A check valve (fluid on-off valve device) capable of attaining high sealability in either case where a differential pressure is high or low, comprises a valve body assembly (valve body) contacting and separating from a valve seat portion for communicating and blocking a fluid passage. The valve body assembly comprises a valve body, a low-pressure seal portion constituted out of soft material and a high-pressure seal portion constituted out of harder material than the low-pressure seal portion. In blocking a fluid passage, when a differential pressure between an upstream path and a downstream path in the fluid passage is relatively low, the low-pressure seal portion comes into close contact with a protrusion to block the fluid passage, while when the differential pressure is relatively high, the low-pressure seal portion is compressively deformed by the differential pressure and the high-pressure seal portion comes into close contact with the valve seat body, thus blocking the fluid passage.
