20110247726 | GAS FILLING SYSTEM, GAS FUEL VEHICLE AND GAS STATION - A gas filling system, a gas fuel vehicle and a gas station capable of avoiding the joint of a receptacle and a nozzle freezing and filling a gas smoothly is provided. A gas filling system comprises: a gas fuel vehicle including a receptacle; and a gas station which sends and fills a cooled gas via a filling nozzle connected to the receptacle into a tank in the gas fuel vehicle, wherein the gas filling system comprises a waterproof cover which covers a joint of the receptacle and the filling nozzle. | 10-13-2011 |
20120132298 | VALVE SYSTEM OF HIGH PRESSURE TANK FOR VEHICLE - A valve system includes a fusible plug valve that functions as a fusible plug valve and as a manual valve. When functioning as a fusible plug valve, the fusible plug valve opens at a high temperature to release gas from a high pressure tank to outside. When functioning as a manual valve, the fusible plug valve is opened manually to release the gas from the high pressure tank to the outside. | 05-31-2012 |
20130014855 | FUEL LEAKAGE DETECTION SYSTEM AND DETECTION METHODAANM Yahashi; HirokiAACI Toyota-shiAACO JPAAGP Yahashi; Hiroki Toyota-shi JPAANM Okawachi; EijiAACI Toyota-shiAACO JPAAGP Okawachi; Eiji Toyota-shi JPAANM Ishitoya; TsukuoAACI Toyota-shiAACO JPAAGP Ishitoya; Tsukuo Toyota-shi JP - A fuel leakage detection system comprises: a communication part for acquiring data relating to fuel filling of an onboard fuel tank from the vehicle side when a fuel supply part is connected to a filler port; a fuel flow rate measurement part, provided on the upstream of the fuel supply part 18, for measuring the flow rate of fuel flowing to the fuel supply part; a fuel flow-out permission part for permitting/stopping the outflow of fuel to the fuel supply part; and a control unit for controlling the fuel flow-out permission part. The control unit further comprises a fuel leakage detection part for detecting fuel leakage when filling fuel to a vehicle based on the fuel flow rate acquired by the fuel flow rate measurement part and on data relating to fuel filling acquired from the vehicle side via the communication part, and the fuel flow out permission part stops outflow of fuel to the fuel supply part when occurrence of fuel leakage is detected by the fuel detection part. | 01-17-2013 |

20130206257 | FUEL SUPPLY SYSTEM - A fuel supply system includes a fuel gas tank; a temperature detecting portion; a fuel gas discharge flow path; a main stop valve that is provided in the fuel gas discharge flow path; and a control portion. The main stop valve includes an inlet portion and an outlet portion, a main valve that is arranged between the inlet portion and the outlet portion and that opens and closes the fuel gas discharge flow path, a pilot flow path that is provided so as to communicate the inlet portion with the outlet portion, a pilot valve that opens and closes the pilot flow path, and an actuator capable of opening and closing the main valve and the pilot valve at different timings. The control portion opens the pilot valve and closes the main valve when the detected temperature is equal to or lower than a first reference temperature. | 08-15-2013 |
20150137022 | VALVE MAIN UNIT AND METHOD OF MANUFACTURING THE SAME - A valve main unit, in which a high pressure valve is to be provided, includes a channel for hydrogen gas. An internal surface of the channel is constituted by an oxidation layer formed by performing anodizing on an aluminum-based alloy. The oxidation layer of the channel is formed by performing the anodizing under a condition in which the oxidation layer with a thickness of | 05-21-2015 |
