20080290196 | Deformation-Optimized Armature Guide For Solenoid Valves - The invention relates to a fuel injector having a solenoid valve for actuating an armature assembly which is configured in one piece or a plurality of pieces. A closing element is actuated via this in order to relieve the pressure in a control chamber. The armature assembly is guided in an armature guide which is fastened in the injector body by means of a valve-clamping screw. In a fixing region in the injector body, the armature guide has at least one circumferential recess which allows for deformation of the fixing region during fastening by the valve-clamping screw. | 11-27-2008 |

20100294240 | INJECTOR FOR INJECTING FUEL INTO COMBUSTION CHAMBERS OF INTERNAL COMBUSTION ENGINES - The invention relates to an injector for injecting fuel into combustion chambers of internal combustion engines. According to the invention, a valve seat of a control valve is designed as a flat seat that has a planar valve seat surface. A circumferential edge located on the face of a sleeve of the control valve rests on the planar valve seat surface when the control valve is closed. | 11-25-2010 |
20100319660 | Fuel Injector Having An Additional Outlet Restrictor Or Having An Improved Arrangement Of Same In The Control Valve - The present invention relates to a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine, having a valve piston that is displaceably guided in an injector body in terms of lifting motions, whereby the lifting motion of the valve piston can be controlled by a control valve. The control valve has a valve needle with a guide bore, so that the needle is displaceably guided in the direction of a lifting axis in terms of lifting motions. A guide section integrally formed on an end of a valve piece extends into the guide bore for the displaceable guidance of the valve needle in terms of lifting motions. Along the lifting axis a vertical bore extends through the valve piece into the guide section, such that fuel is able to flow through the bore from a control chamber into an annular chamber introduced between the guide bore and the guide section for controlling the lifting motion of the valve piston. The fuel volume conducted through the vertical bore furthermore flows through at least one outlet restrictor, which is disposed in the region of the transition from the vertical bore into the annular chamber. | 12-23-2010 |

20140352939 | EVAPORATOR TUBE HAVING AN OPTIMISED EXTERNAL STRUCTURE - The invention relates to a metal heat exchanger tube for the evaporation of liquids on the outside of the tube, comprising a tube axis, a tube wall, and integrally formed ribs that run circumferentially on the outside of the tube. The ribs have a rib foot, rib flanks, and a rib tip, wherein the rib foot projects substantially radially from the tube wall. A respective groove is located between every two ribs that are adjacent to one another in the axial direction. At least first, second, and third lateral material projections, which are formed from the material of the ribs, are arranged on a first, second, and third level on the rib flanks in such a way that the grooves are largely covered by all of the material projections. According to the invention, the first, second, and third lateral material projections are formed on levels that are in each case differently spaced apart from the tube wall in the radial direction. | 12-04-2014 |

20090157086 | Bone plate instrument and method - A drill guide for a bone plate which has holes therethrough for receiving bone screws. The drill guide includes a guide block having drill guide bores alignable with at least two bone screw receiving holes in the bone plate. A first locking element in inserted through a guide block drill guide bore. The locking element has a tip for engaging a bone screw receiving holes in the bone plate, the tip being selectively expandable to engage and disengage from the bone plate hole. A second locking element is mounted on the guide block and is engageable with a bone plate hole. The second locking element also has a tip for resiliently engaging walls of the bone plate hole wherein the tip of the first and second locking elements has a split portion. The first and second locking elements include an axially moveable rod for expanding the split tip portion to engage the plate | 06-18-2009 |
