20080265054 | Injector With A Pressure Intensifier That Can Be Switched On - An injector in which it is possible to switch a pressure booster on or off so that it is possible to control not only the injection duration, but also the progression of the injection pressure within a broad range during the injection. | 10-30-2008 |
20100019068 | FUEL INJECTOR WITH AN INTEGRATED PRESSURE BOOSTER - Proposed is a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector has a housing in which are arranged an injection valve element with a nozzle needle, a pressure boosting device, and a first control valve, and a second control valve. The first control valve controls a control space of the nozzle needle and the second control valve controls a differential pressure space of the pressure boosting device. A first return flow connection is provided for discharging the control quantity of the control space of the nozzle needle, and a second return flow connection is provided for discharging the control quantity of the pressure boosting device. The two return flow connections are arranged on different housing parts of the housing. | 01-28-2010 |
20110168812 | FUEL INJECTOR WITH PISTON RESTORING OF A PRESSURE INTENSIFIER PISTON - The invention relates to a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine, which fuel injector comprises an injection valve element, for opening and closing at least one injection opening and a pressure booster, by way of which fuel which is at system pressure is compressed to injection pressure. The pressure booster is actuated via a first control valve and the injection valve element is actuated via a second control valve. The pressure booster comprises a pressure booster piston which is assigned a spring element which is supported by way of one side on the injector housing and by way of the other side on the pressure booster piston. The pressure booster piston delimits a compression chamber, a differential pressure chamber and a control chamber. The control chamber is arranged at that end of the pressure booster piston which lies opposite the compression chamber, the spring element is received in the control chamber, and the spring element is supported on one side on the injector housing and on the other side on the pressure booster piston. | 07-14-2011 |

20080314188 | Steering Column Arrangement For A Motor Vehicle - A steering column arrangement includes a steering spindle, which rotates about its longitudinal axis and serves to transfer a torque, generated by a steering wheel, to a steering gear, and a blocking device, which prevents the rotational motion of the steering spindle, especially in the event of a collision. The blocking device includes a stator, which is stationary in relation to the rotational motion of the steering spindle, and against which a blocking element is mounted in a relatively moveable manner. To prevent, in a reliable manner, an undesired twisting of the steering wheel, especially in the event of a collision, the blocking element is moveable into a locked position in a radial direction toward the steering spindle. | 12-25-2008 |
20090160153 | Wheel Suspension for a Front Axle of a Motor Vehicle - As a result of a configuration and position of an upper transverse link and of a lower transverse link, a wheel pivot axis is created which has a point of intersection with an area region of a vertical wheel central transverse plane and a wheel central longitudinal plane. An adjustment of the wheel in a toe-out sense takes place under the influence of braking forces and an adjustment of the wheel in a toe-in sense takes place under the influence of drive forces. Furthermore, as a result of different mount characteristics at the lower transverse link and at the track rod, it is ensured that, in the event of side forces, the wheel which is at the outside of the corner is adjusted in a toe-out sense. | 06-25-2009 |
20090160154 | WHEEL SUSPENSION FOR THE REAR WHEELS OF A MOTOR VEHICLE - A wheel suspension for the rear wheels of a motor vehicle is created, with three links being provided in an upper link plane, and with a foremost link as viewed in the direction of travel being provided as a track rod and the two further links being provided as separate individual links at both sides of a vertical wheel central transverse plane. A triangular link is arranged in the lower link plane, which triangular link holds a spiral or air spring and a damper strut spaced apart from one another. By corresponding pole formations defined by the links, elastokinematic or imaginary pivot axes are formed, which permits an elastokinematic adjustment of the wheel in a toe-in sense under the influence of braking forces, side forces and load shift forces. The wheel suspension is also configured such that an elastokinematic adjustment of the wheel in a toe-out sense is obtained in the event of wheel loads and drive forces. | 06-25-2009 |
20090212548 | Subframe for a Rear Axle of a Motor Vehicle - The subframe contains a framework which is cast as a single part and has profiled hollow members for the longitudinal and cross members. The cross members are connected to each other via supporting pillars at the corners, or are integrally formed on the supporting pillars. Arms which protrude outward are integrally formed on the supporting pillars or on the longitudinal and cross members, the end sides of which arms have connecting bearings toward the vehicle body. A differential is held on the two cross members, the differential having one mounting on the front cross member and two mountings on the rear cross member. The longitudinal members have a curved passage opening for the drive shafts of the differential. Mountings for wheel guiding links are arranged on the outside of the longitudinal member. | 08-27-2009 |
