20090151797 | PRESSURE REGULATOR - The present invention discloses a pressure regulator comprising: a housing having an inlet opening for the supply of pressurized fluid under primary pressure from a pressurized fluid source and an outlet opening for discharging the pressurized fluid under a secondary reduced pressure, a channel between the aforementioned inlet opening and outlet opening; and a pressure-regulating mechanism for reducing the aforementioned primary pressure to the aforementioned secondary pressure. The pressure regulator's pressure-regulating mechanism has a movable body that comprises a diaphragm which is displaceable in response to pressure fluctuations, the inlet opening and the movable body being in line with each other in the direction substantially perpendicular to the direction of the diaphragm displacement. The present invention is reduces the dimensions while extending the service life of a pressure regulator intended for decrease of fluid pressure even when the pressure regulator operates with fluids such as high-pressure gas with corrosive properties. | 06-18-2009 |
20090155669 | FUEL-CELL CONNECTOR - To reduce leakage of fuel from a fuel cartridge during connection to and disconnection from a fuel-cell connector. A fuel-cell connector for releasable connection to a fuel cartridge has a cartridge-side connection element with a cartridge-side valve that opens or closes a fuel-supply opening. A fuel-cell connector has a connector-side valve that opens and closes a fuel-receiving opening and moves, during the first insertion stage, together with the cartridge-side valve, and a resilient element for resisting movement in the insertion direction of a connector body unit into which the cartridge-side connection element is telescopically inserted. The connector body unit has on its outer periphery engagement means for engagement with the cartridge-side connection element and a stationary mechanism part for attachment to the fuel-cell-using device. In the second insertion step, the aforementioned connector body unit is moved as a single unit with the cartridge-side connection element, while the fuel-receiving opening and the fuel-supply opening are maintained in close proximity and so that the aforementioned engagement means are engaged with the cartridge-side connection element, whereby the fuel cartridge is connected and fixed in the connected position. | 06-18-2009 |
20090169960 | Flow rate regulation filter, and fuel container for fuel cell - A flow rate regulation filter provided in a discharge flow path of a fuel container for a fuel cell. The fuel container receives liquid contents of a liquid fuel for a fuel cell such that the contents can be discharged as a liquid or a gas, and the flow rate regulation filter regulates the amount of discharge of the liquid contents. The flow rate regulation filter comprises an elastic body having continuous bubbles and a holder constructed from a formed body fusion-bonded to the elastic body and fixing the elastic body so that the elastic body closes the discharge flow path, and the elastic body and the holder are formed of a thermoplastic resin not corroded by the liquid contents. The discharge flow rate of the contents in the fuel container for a fuel cell can be regulated without requiring a major construction such as a liquid amount regulation mechanism. | 07-02-2009 |
20090208811 | Fuel Cell Cartridge Connector - The problem to solve is providing a fuel-cell cartridge connector that protects the fuel-cell-holding appliance from damage when a external force which exceeds the allowable range, is applied to the fuel cell cartridge. To solve the problem a fuel-cell connector ( | 08-20-2009 |
20090214287 | CONNECTOR STRUCTURE WITH LOCK MECHANISM - A connector structure securely connectable in a locked state and releasable by an easy operation, comprising a supplying connection part for supplying a fluid and receiving connection part for receiving the supply of fluid. The connector structure also comprises a securing mechanism having an operating member moving according to a connecting operation between the supplying connection part to the receiving connection part, holding the connected state of the supplying part to the receiving part in a securely locked state and releasing the locked state of the supplying part to the receiving part by movement of the operating member according to the next pressing-in operation of the supplying part and an energizing mechanism energizing the supplying part in the separating direction thereof from the receiving part. When in the locked state, the pressurized fluid can be supplied from the supplying connection part to the receiving connection part. | 08-27-2009 |
20110048553 | PRESSURE REGULATOR - A pressure regulator includes a housing having an inlet port through which pressurized fluid at a primary pressure is supplied, and a discharge port through which pressurized fluid at a secondary pressure lower than the primary pressure is discharged, and at the same time having a flow passage formed therein to extend from the inlet port to the discharge port, and a pressure control mechanism which is disposed on the flow passage to reduce the primary pressure to the secondary pressure. The pressure control mechanism includes a movable body including a diaphragm which is displaced in response to change in the pressure of the fluid and the movable body is provided with an abutment portion which is brought into abutment against a part of the housing to prevent the movable body from being excessively displaced when the primary pressure becomes excessively high. | 03-03-2011 |
20110123905 | FUEL CONTAINER FOR FUEL CELL - A fuel container for fuel cells is equipped with a container main body, containing liquid fuel therein to be supplied to a fuel cell, equipped with a connecting port, for connecting with the fuel cell or a pressure adjusting device, and extruding means, for extruding the liquid fuel. The fuel container is also equipped with a partitioning member, which is slidably provided within the container main body, for partitioning the interior of the container main body into a fuel storage chamber, in which the liquid fuel is contained, and an extruding means housing chamber, in which the extruding means is housed. The fuel container is further equipped with a valve provided in the connecting port, for enabling or preventing the flow of the liquid fuel. The frictional force generated at the surfaces of the connector main body and the partitioning member, which are in sliding contact, is 10N or less. | 05-26-2011 |
20120129081 | FUEL CARTRIDGE - The existing problem is supplying fuel at a fixed flow rate to a fuel cell, and moreover, miniaturization of the device in which the fuel cell is loaded, in a fuel cartridge for a fuel cell. The fuel cartridge for a fuel cell is equipped with a container main body that is equipped with a connection part that connects to the fuel cell, and houses the fuel that is supplied to the fuel cell in its interior, and a push out means for pushing out the fuel, and a valve that has a supply port for supplying fuel to the fuel cell, and that opens the supply port in response to the operation connecting the container main body to the fuel cell. On the connection part there is provided a pressure regulating mechanism, one end of which communicates with the valve, and the other end of which communicates with the inside of the container main body, and that causes the fuel that is housed in said interior to flow out to the valve, by regulating to a secondary pressure lower than the primary pressure inside the container main body. | 05-24-2012 |
