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 |
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 |

20090139595 | Connecting Head Stucture For High-Pressure Fuel Injection Pipes - A thick-wall small-diameter high-pressure fuel injection pipe has a spherical seat surface, an annular flange, and a conical surface continued from the seat surface at a connecting end of the pipe. If the pipe is configured so that t (thickness)/D (outer diameter)<0.3, then an axial distance from the connecting head end to the back face of the annular flange is 0.38D to 0.6D, a spherical radius of the seat surface is 0.45D to 0.65D, the annular flange outer diameter is 1.2D to 1.4D, and an inner peripheral surface of the head has a substantially flat cylindrical surface or a conical surface. If the pipe is configured so that t (thickness)/D (outer diameter)≧0.3, then the axial distance from the connecting head end to the back face of the annular flange is 0.38D to 0.7D. | 06-04-2009 |
20090151701 | Connection Head Structure of High Pressure Fuel Injection Tube - A connection head structure of a high pressure fuel injection tube is provided to avoid an interference between an annular flange and an opposing part by sufficiently maintaining an tube axial direction length of the connection head and to obtain a good sealability to prevent leaking during autofrettage processing with a high pressure of not less than 300 MPa. A connection head structure of a high pressure fuel injection tube includes, on a connection end portion of a thick walled fine steel tube, a spherical seat face, an annular flange, and a circular conic face that continuously extends from the seat face, wherein a washer and a fastening nut are assembled, characterized in that when a thick walled fine steel tube has t (wall thickness)/D (outer diameter)<0.3, an tube axial direction distance L | 06-18-2009 |
20110108005 | FUEL RAIL FOR HIGH-PRESSURE DIRECT-INJECTION INTERNAL COMBUSTION ENGINES AND METHOD FOR MANUFACTURING THEREOF - A fuel rail for high-pressure direct-injection internal combustion engines has an injector holder and a fastening bracket directly attached to a main body of the fuel rail. Thermal deformation may occur at the time of temporary fitting or brazing when assembling the rail. However, positional accuracy of the injector holder can be assured, which results in having an excellent sealing property. Components of the fuel rail for direct-injection internal combustion engines are made of steel or stainless steel, and the components are joined reciprocally by brazing. The components joined by brazing are finished by cutting work and/or burnishing processing after the brazing step. | 05-12-2011 |
