| 20110017844 | FUEL INJECTOR WITH AN IMPROVED VALVE CONTROL ARRANGEMENT - A fuel injector for a compression ignition internal combustion engine which comprises a fuel injection valve having an injection valve member which is moveable in use, under the influence of fuel pressure within an injection valve member control chamber acting upon it, between a closed position and an open position. The fuel injector further comprises a high pressure fuel supply passage to the injection valve member control chamber, and an actuator operable to open and close a discharge valve connected between the injection valve member control chamber and a fuel outlet passage to a low pressure reservoir or drain. A shut-off valve is provided in the high pressure fuel supply passage and the shut-off valve has a shut-off valve member which is moveable in use, under the influence of fuel pressure within a shut-off valve member control chamber acting upon it, between a closed position and an open position. The shut-off valve member control chamber is connectable to the low pressure reservoir or drain via the discharge valve, and a fuel transfer passage is provided between the injection valve member control chamber and the low pressure reservoir or drain. | 01-27-2011 |

| 20090186547 | REINFORCING FIBER TEXTURE WITH MULTIPLE-SATIN WEAVING FOR A COMPOSITE MATERIAL PART - A reinforcing fiber texture for a composite material part is made by multi-layer three-dimensional weaving with a satin type weave or a multiple satin type weave. The texture comprises at least three layers of weft yarns T interlaced by warp yarns C, each warp yarn taking hold in alternation of one weft yarn in n from a first layer of weft yarns and of one weft yarn in n of a second layer of weft yarns adjacent to the first, the number n being an integer not less than 3. The paths of the warp yarns are similar and they are offset in the warp direction. | 07-23-2009 |

| 20100144227 | REINFORCING FIBROUS STRUCTURE FOR A COMPOSITE MATERIAL AND A PART CONTAINING SAID STRUCTURE - A woven fibrous structure embodied in one piece, used for producing a composite material part and comprising an internal part or a core ( | 06-10-2010 |
| 20110121109 | METHOD OF PRODUCING A NOZZLE OR A DIVERGENT NOZZLE ELEMENT MADE OF A COMPOSITE - A fiber preform obtained by conforming panels of fiber texture on a former having a surface that reproduces the shape desired for a surface of the nozzle or the nozzle divergent section that is to be made, and by bonding the panels together via their mutually contacting edges, and consolidated fiber reinforcement is formed by shaping the fiber preform impregnated with a consolidation composition comprising a resin, shaping being performed between the former and a jacket applied against the impregnated fiber preform so as to obtain consolidated fiber reinforcement having a fiber volume percentage of at least 35%, and having a thickness of no more than 5 mm over at least a major fraction of its axial dimension. The densification of the fiber reinforcement is continued by chemical vapor infiltration after pyrolyzing the resin so that once densified a part is obtained that has practically the shape and the wall thickness of the nozzle or the nozzle divergent section that is to be made. | 05-26-2011 |
