Abstract: A computer implemented method, and apparatus, and a computer readable media for automated processing of standard cost estimates for business activities. A standard cost estimate indicating standard costs of a business activity is defined. A design pattern is used to encapsulate product characteristics including, defining at least one change request based on a production scenario, and modifying the standardized cost estimate. An updated standardized cost estimate indicating updated cost of the business activity based on the at least one change request is then derived.

Abstract: A high-pressure pump having a drive shaft and at least one pump element including a pump piston driven in a reciprocating motion by the drive shaft. A ring on which the pump piston is braced via a support element is rotatably supported on a portion of the drive shaft that is disposed eccentrically to its pivot axis. The ring and/or the support element, at least in their contact region, has many microscopic indentations, and a solid lubricant film is applied to the ring and/or to the support element, at least in their contact region.

Abstract: A fuel supply system, having a housing, in which a pistonlike element is disposed longitudinally displaceably in a bore and is guided sealingly in the bore by a guide portion. On one end, the guide portion adjoins a first fuel-filled chamber, and on its other end it adjoins a second fuel-filled chamber. At least one recess extending at least approximately in the circumferential direction is embodied in the guide portion of the pistonlike element and extends over at least part of the circumference of the pistonlike element and, viewed in the longitudinal direction of the pistonlike element, has an asymmetrical cross section.

Abstract: A device for supplying fuel at high pressure to an internal combustion engine, having a pistonlike element which is disposed longitudinally displaceably in a bore of a component. The pistonlike element is guided with a sealing portion in a guide portion of the bore, and the guide portion discharges at one end into a pressure chamber that can be filled with fuel at high pressure and at the other end into a leak fuel chamber. At least one channellike recess is embodied on the sealing portion of the pistonlike element, or the guide portion and this recess communicates hydraulically with the pressure chamber and is sealed off from the leak fuel chamber, except for the annular gap formed between the pistonlike element and the inner wall of the guide portion, and as a result the pistonlike element is hydraulically centered in the bore.

Abstract: A fuel injection valve for internal combustion engines, having a valve body in which a pistonlike valve needle is disposed in a bore is defined on its end toward the combustion chamber by a valve seat, which cooperates with a valve sealing face embodied on the valve needle, so that by the longitudinal motion of the valve needle, the opening of at least one injection opening embodied on the end toward the combustion chamber of the valve body is controlled. On the valve sealing face and/or on the valve seat, microscopic indentations are embodied.

Abstract: A device for supplying fuel at high pressure to an internal combustion engine, having a pistonlike element (5) which is disposed longitudinally displaceably in a bore (3) of a component (1). The pistonlike element (5) is guided with a sealing portion (105) in a guide portion (103) of the bore (3), and the guide portion (103) discharges at one end into a pressure chamber (19) that can be filled with fuel at high pressure and at the other end into a leak fuel chamber (15). At least one recess (30) is embodied on the sealing portion (105) of the pistonlike element (5), and this recess communicates hydraulically with the pressure chamber (19) and is sealed off from the leak fuel chamber (15), except for the annular gap (17) formed between the pistonlike element (5) and the inner wall of the guide portion (103), and as a result the pistonlike element (5) is hydraulically centered in the bore (3) (FIG. 1).
