| 20100258085 | COUPLING DEVICE - A coupling device for hydraulically and mechanically coupling an injection valve to a fuel rail of a combustion engine has a fuel injector cup with a central longitudinal axis and can be hydraulically coupled to the fuel rail and engages a fuel inlet tube of the injection valve, a first retaining element is fixedly coupled to the cup, a second retaining element is fixedly coupled to the valve, the second element being coupled to the first element to prevent a movement of the second element relative to the first element in a first direction of the central longitudinal axis to retain the valve in the cup, and a damper element which is arranged axially between the cup and the valve body. The damper element limits a movement of the valve relative to the cup in a second direction of the central longitudinal axis opposing the first direction. | 10-14-2010 |
| 20100313851 | COUPLING DEVICE AND FUEL INJECTION ARRANGEMENT - A coupling device for hydraulically and mechanically coupling an injection valve to a fuel rail of a combustion engine has a fuel injector cup with a central longitudinal axis, is hydraulically coupled to the fuel rail and in engagement with the injection valve. A first retaining element is fixedly coupled to the fuel injector cup, a second retaining element is fixedly coupled to the injection valve, the second retaining element being coupled to the first retaining element to prevent a movement of the second retaining element relative to the first retaining element in a first direction of the central longitudinal axis to retain the injection valve in the fuel injector cup, and an interface element which is operable to axially couple the injection valve with the second retaining element in a fixed way. Fuel injection arrangement with a coupling device and an injection valve which is coupled to the coupling device. | 12-16-2010 |

| 20100264231 | COUPLING DEVICE - A coupling device for hydraulically and mechanically coupling an injection valve to a fuel rail of a combustion engine, has a fuel injector cup with a central longitudinal axis which can be hydraulically coupled to the fuel rail and at least partially engaged with the fuel inlet tube. The cup has an inner bottom surface facing the valve, a first retaining element fixedly coupled to the cup, a second retaining element fixedly coupled to the valve, wherein the second retaining element is coupled to the first element to prevent a movement of the second element relative to the first element in a first axis direction, and a damper element which is arranged axially between the inner bottom surface of the cup and the inlet tube. The damper element limits a movement of the valve relative to the cup in a second direction of the longitudinal axis opposing the first direction. | 10-21-2010 |

| 20090184512 | COUPLING ARRANGEMENT AND CONNECTION ASSEMBLY - Coupling arrangement ( | 07-23-2009 |
| 20090235899 | Coupling Arrangement - A coupling arrangement has a fuel injector cup with a central longitudinal axis coupled to a fuel rail at a first axial end area and to a ring element at a second axial end area by a circlip. The cup has at least two slots arranged at the second end area and at least two grooves arranged at least partly circumferentially the cup and axially overlapping with the slots. The ring element is arranged at the central longitudinal axis facing the second end area and coupled to a housing. The ring element has at least two protrusions facing the cup having at least two grooves arranged at least partly circumferentially the ring element in a common plane with the grooves. The circlip is arranged at least partly circumferentially the cup at least partly in the grooves and arranged at least partly circumferentially the ring element at least partly in the grooves. | 09-24-2009 |
| 20100170477 | Coupling Device - Coupling device for hydraulically and mechanically coupling a fuel injector to a fuel rail of a combustion engine. The fuel injector has a central longitudinal axis. The coupling device has a fuel injector cup being designed to be hydraulically coupled to the fuel rail and to engage a fuel inlet portion of the fuel injector, a first plate element being fixedly coupled to the fuel injector cup, the first plate element comprising a recess, and a second plate element being fixedly coupled to the fuel injector and being arranged in the recess and being fixedly coupled to the first plate element to retain the fuel injector in the fuel injector cup in direction of the central longitudinal axis. The fuel injector comprises a groove. A snap ring is arranged in the groove of the fuel injector and is designed to fixedly couple the second plate element to the fuel injector. | 07-08-2010 |
| 20100218743 | FASTENING ELEMENT AND FLUID INJECTOR ASSEMBLY - A Fastening element has a carrier. A first pair of prongs branches off a first side face of the carrier designed to be in a mechanical engagement with a protrusion of a injector cup. A second pair of prongs branches off a second side face of the carrier. The second pair of prongs is designed to retain a fluid injector and to couple mechanically to a first protrusion of the injector. A pair of pins branches off a respective prong from the second pair of prongs at a respective inner side face of the respective prong. The pins are arranged opposed to each other and in a given distance from each other and they are designed to be in a mechanical engagement with the fluid injector. A clamping device being designed to couple mechanically with the fluid injector cup and to exert a repelling force on the fluid injector cup. | 09-02-2010 |
