20130095398 | PRESSURE-REDUCING VALVE WITH INJECTOR AND FUEL CELL SYSTEM INCLUDING PRESSURE-REDUCING VALVE - A pressure-reducing valve with an injector of the present invention includes a shuttle valve body, a shuttle valve seat in which the shuttle valve body is capable of coming into contact with and be separated, a back-pressure chamber, a back-pressure channel that communicates with the back-pressure chamber and discharges the fluid of the back-pressure chamber, a biasing portion that biases the shuttle valve body in a direction of coming into contact with the shuttle valve seat, and an injector that adjusts an intermittent time interval of the fluid in the back-pressure chamber discharged through the back-pressure channel and discharges the adjusted fluid to a discharging port or a channel that communicates with the discharging port. | 04-18-2013 |
20130164648 | FUEL-USING SYSTEM - An electromagnetic main stop valve which is opened by an electromagnetic force of a solenoid with energization of a valve body in a valve-closing direction by energizing unit is provided in a hydrogen tank. A current sensor and the accelerator opening-degree sensor for detecting a use gas flow rate in a fuel cell stack are provided. A pressure sensor for detecting a pressure in the hydrogen tank is provided. The control device sequentially sets the electromagnetic force of the solenoid so that a valve-opening amount is such an amount as to supply a use gas flow rate to the fuel cell stack based on detection values of the current sensor or the accelerator opening-degree sensor, and the pressure sensor. When the flow rate of hydrogen gas flowing into a gas supply path increases due to a hydrogen gas leak, the main stop valve is automatically closed. | 06-27-2013 |
