摘要： A fuel supply device includes a fuel pump, a plurality of valves, and a controller. The fuel pump includes a plurality of pressure chambers each having a volume that is expanded and contracted by the engine. The plurality of valves open and close the pressure chambers. An expansion time and a contraction time of the pressure chambers are each different. The fuel pump is operable to sealingly store fuel in the pressure chambers by closing the valves. The controller sets closing times for the valves in accordance with a required quantity of fuel to be force fed. The controller switches between a normal control in which all of the pressure chambers sequentially force feed fuel and a thinned-out control in which the force fed fuel is thinned out by stopping closing at least one of the valves.

摘要： A fuel injection valve having a valve retaining body (1), which has a longitudinal axis (2) and in which a central spring chamber (5) is embodied. In this spring chamber (5), a closing spring (6) is disposed, which transmits a closing force to a valve member (30), which valve member (30) cooperates with a valve seat (32) for controlling at least one injection opening (36). In the wall of the spring chamber (5), an inlet conduit (3) extends parallel to the longitudinal axis (2) of the valve retaining body (1), and by way of this conduit, fuel at high pressure can be delivered to the at least one injection opening (36). The cross section of the inlet conduit (3) has a greater length in the circumferential direction than in the radial direction, so that the wall region between the inlet conduit (3) and the spring chamber (5), or the outer jacket face of the valve retaining body (1), is larger than in the case of an inlet conduit (3) with the same size of cross-sectional area and a circular cross-sectional contour (FIG. 1).

摘要： Fuel injector for an internal combustion engine which has a timing chamber bore in its body intersecting at an acute angle with an auxiliary bore. These bores are fuel-receiving passages exposed to the pressure of injection. A radiused intersection between the walls of the respective bores reduces the concentration of stress within the fuel injector, allowing the injector to withstand the high injection pressures of mechanical pressurization. An electrochemical machining method and fixture for machining the intersection between the bores of a fuel injector body or other workpiece is also disclosed.

摘要： The invention relates to an electromagnetically actuatable intake valve for a high-pressure pump of a fuel injection system, in particular a common rail injection system, comprising a magnet coil (1) for acting on an armature (2) which is received and guided such that it can be moved with a reciprocating movement in a central recess (3) of a valve body (4), wherein a pole core (6) which is connected via a sleeve (7) to the valve body (4) lies opposite the armature (2) at a working air gap (5). According to the invention, the valve body (4) has a circumferential cut-out (9) within an inner circumferential surface (8) which delimits the recess (3), which cut-out (9) divides the inner circumferential surface (8) into an upper and a lower guide region (10, 11). The invention also relates to a high-pressure pump for a fuel injection system, in particular a common rail injection system, comprising said type of intake valve.

摘要： A gas turbine fuel injector assembly including one or more dampers for damping vibration of one or more fuel conduits in the assembly. The dampers may at least partially surround the fuel conduits, and each damper has an intermediate portion that is bowed relative to axial end portions to form a pocket, which enables the damper to be free to flex radially for damping vibration experienced by the fuel conduit during operation. The damper may be a wire mesh damper formed with interwoven wires that are configured to move relative to each other in response to vibrational movement of the fuel conduit. The wire mesh damper also may enable fluids, such as gases or fuel, to flow through gaps in the wire mesh. The damper may support and damp individual fuel conduits, thereby enabling the fuel conduits to thermally expand independently of each other in the assembly.

摘要： A fuel injector assembly has a control valve body and a plurality of end caps. End cap locating holes are formed into a mating surface of each end cap, and control valve body locating holes are formed into each mating surface of the control valve body. Locating pins inserted into the end cap and control valve body locating holes each have a fixed portion that affixes the locating pins to either the control valve body or the end cap. In the event of failure of a locating pin between the fixed portion and a free portion of the pins, the free portion maintains alignment of the control valve body locating holes with the end cap locating holes.
