20090127356 | FUEL INJECTOR - The invention relates to a fuel injector for injecting fuel into a combustion chamber, having a solenoid valve for controlling a mini-servo valve. A movable armature can be placed in a sealing fashion on a valve seat in a lower armature chamber, wherein in addition the mini-servo valve is held in an injector body and seals a control line against a flat seat. By means of the flat seat, during an actuation of the solenoid valve, the control line can be relieved of pressure from a high fuel pressure to a return pressure into at least one return line. A mechanism for reducing pressure oscillations are provided in the at least one return line, which includes at least one diaphragm cell which is held in a recess and which is placed in fluidic connection with the at least one return bore. A fuel injector with the mechanism for reducing pressure oscillations is therefore created in the at least one return line which operates without a leakage flow and has a simple and effective function. | 05-21-2009 |
20090159727 | FUEL INJECTOR WITH A PRESSURE-COMPENSATED CONTROL VALVE - In a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine, an injection valve member for opening and closing at least one injection opening is triggered by a control valve embodied as a magnet valve. On the armature of the magnet valve, a sealing face is embodied that for closing the control valve is positionable into a valve seat. The armature of the magnet valve is movable, without armature guidance, between an upper and a lower stroke stop. Because the sealing face, which for closing the control valve is positionable into the valve seat, is embodied on the armature, an additional closing element of the kind provided in the prior art can be dispensed with. | 06-25-2009 |

20090260598 | ARRANGEMENT WITH A PIEZOELECTRIC ACTUATOR AROUND WHICH FLUID MEDIA FLOW - An arrangement with a piezoelectric actuator is disclosed, made up of a piezoelectric element with a multilayer construction of piezoelectric layers. The piezoelectric actuator is surrounded by an inner chamber at least surrounding the layers, which filled with a fluid insulation medium. The inner chamber is sealed from a fluid medium in an outer chamber an elastic sleeve which can change shape. The sleeve is sealed with sealing elements being provided at the axial ends thereof in the region of an actuator base and an actuator head. By a shape and/or positional change of the sealing elements, corresponding to the elasticity of the sleeve, a volume equalization in the inner chamber with the insulation medium is achieved. | 10-22-2009 |
20090266340 | FUEL INJECTOR - The invention relates to a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine. A fuel supply line enters an injector housing from a high pressure fuel source which can be hydraulically connected to a pressure chamber. A 3/2 directional control valve for injecting fuel into the combustion chamber has a valve piston which can be moved axially back and forth between a rest position and an injection position. The 3/2 directional control valve, by a first end face of the valve piston, which adjoins a hydraulic coupling chamber, is hydraulically coupled to and can be activated by a piezoelectric actuator. The 3/2 directional control has a ball element which is connected to a second end face of the valve piston and, in the rest position, can be moved against a first sealing edge and, in the injection position, can be moved against a second sealing edge. The diameter of the valve piston and the diameter of the first sealing edge have a ratio which permits the ball element to be pressed in the rest position with a small contact force against the first sealing edge. A fuel injector with a 3/2 directional control valve is therefore created which has a simple design, and complex production processes are dispensed with. | 10-29-2009 |
20090277421 | FUEL INJECTOR - The invention relates to a fuel injector, in particular a common rail injector, for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector has an injection valve element which is adjustable between a closing position and an opening position and which is switchable by means of a control valve. The control valve has a sleevelike control valve element that is adjustable along an adjustment axis and in its closing position rests sealingly on a control valve seat element. According to the invention, it is provided that the control valve seat element is disposed movably relative to the adjustment axis of the control valve element. | 11-12-2009 |
20090308354 | FUEL INJECTOR COMPRISING A PRESSURE-COMPENSATED CONTROL VALVE - The invention relates to an injector for injecting fuel into a combustion chamber of an internal combustion engine. According to the invention, an injection valve member, which opens or closes at least one injection opening, is controlled by a control valve. The control valve opens or closes a connection from a control chamber into a fuel return line by the positioning of a closing element in a seat or by the opening of the seat. A bore is embodied in the closing element, and a pin is received in the bore. The diameter of the bore essentially corresponds to the diameter of the seat. The pin is supported on one side against a pressure rod, against a spring seat, or against the injector housing. | 12-17-2009 |
20100116251 | AREA OF INTERSECTION BETWEEN A HIGH-PRESSURE CHAMBER AND A HIGH-PRESSURE DUCT - The invention relates to an area of intersection between a high-pressure chamber and a high-pressure duct. To increase the strength in the area of intersection, it is possible to round the area of intersection. The area of intersection includes at least one planar area or an area that is curved markedly less than the remaining area of intersection. The planar area may also be embodied as only nearly planar. The high-pressure chamber and the high-pressure duct are also called functional chambers. By means of the planar or nearly planar area, an intersection geometry is created, in which tensile stresses of the functional chambers that occur upon subjection to pressure are not superimposed directly and add up as they do in conventional intersection geometries. By means of the planar area in the area of intersection, it is attained that in the intersection geometry of the invention, under pressure, local pressure stresses or markedly reduced tensile stresses occur in an inner wall of the high-pressure chamber and are then superimposed with the tensile stresses in an inner wall of the high-pressure duct. Since with the intersection geometry of the invention, a tensile stress has only a reduced tensile stress or in the best case a pressure stress superimposed on it, the total is less and hence the maximum stress that occurs is reduced markedly. | 05-13-2010 |
20100294241 | FUEL INJECTOR THE CONTROL VALVE ELEMENT OF WHICH HAS A SUPPORT REGION - The invention relates to an injector, in particular, a common-rail injector for injection of fuel into a combustion chamber of an internal combustion engine. An injection valve element, adjustable between a closed position and an open position, is controllable by means of a control valve. The control valve has a control valve element, adjustable between a closed position and an open position by means of an actuator, which in the closed position is an at least almost pressure-equalized and has a sealing line which cooperates in a sealing manner with a control valve seat. The sealing line of the control valve element is lifted off the control valve seat in the open position and hence opens fuel flow from a high pressure region to a low pressure region of the injector. According to the invention, the control valve element has a support region extending over the sealing line in a radial direction to the high pressure region. | 11-25-2010 |
