  • Patent number: 7143965
    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.

  • Publication number: 20050205693
    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.

  • Publication number: 20040079818
    Abstract: A fuel supply system, having a housing (1), in which a pistonlike element (5) is disposed longitudinally displaceably in a bore (3) and is guided sealingly in the bore (3) by a guide portion (105). On one end, the guide portion (105) adjoins a first fuel-filled chamber (19), and on its other end it adjoins a second fuel-filled chamber (15). At least one recess (30) extending at least approximately in the circumferential direction is embodied in the guide portion (105) of the pistonlike element (5) and extends over at least part of the circumference of the pistonlike element (5) and, viewed in the longitudinal direction of the pistonlike element (5), has an asymmetrical cross section (FIG. 1).
