Abstract: Various embodiments may include a high-pressure fuel pump with: a pump housing including a pressure chamber and a pump piston movable up and down within the pressure chamber along a movement axis; and a low-pressure damper including a damper volume arranged on the pump housing and damper elements distributed symmetrically around a damper longitudinal axis. The damper longitudinal axis is arranged at an angle of between 5° and 175° in relation to the movement axis.

Abstract: A roller tappet device for a pump having a drive mechanism is provided. The roller tappet device includes a tappet having a longitudinal axis and a tappet housing having an internal surface area and a housing bearing. The tappet device includes a bearing shell, a bearing-shell clearance, and a pin on a side of the bearing shell that faces away from the bearing-shell clearance. The pin is received in the housing bearing of the tappet housing. The roller tappet includes a roller that has a rotation axis and is rotatably mounted within the bearing-shell clearance. The bearing shell is fixedly coupled to the tappet housing. The roller is supported on the drive mechanism; and during operation of the pump, the roller transmits a force along the longitudinal axis from the drive mechanism by way of the bearing shell to the tappet.

Abstract: A method for producing an electrical circuit between a flexible circuit board (1) is described, with single-sided access and a metallic contact partner (8), such that the contact partner (8) reaches the metallic conductor strip (4) of the circuit board (1) through an access opening (6) in the unit. The circuit board (1) is thus irradiated with laser light (9) in a region opposite the access opening (6) causing a welded connection between the contact partner (8) and the conductor strip (4) to be formed.

Abstract: In a method for producing an electrical connection between a flexible printed-circuit board (1) and a metallic mating contact member (8), an illumination opening (5) is formed in a first insulating layer (2) and a connecting opening (6) is formed in a second insulating layer (3). A section (8a) of the metallic mating contact member (8) is brought into bearing contact with a conductor track (4) through the connecting opening (6). Welding/soldering of the conductor track (4) to the connecting section (8a) is brought about by radiant heating by means of laser light (9) directed through the illumination opening (5).

Abstract: A method for fabricating a flexible printed circuit board with access on both sides includes the steps of applying a metallic conductor track sheet to a base sheet and patterning the metallic conductor track sheet in order to produce conductor tracks. A conductor track covering with first contact-making cutouts is applied over the conductor tracks. Second contact-making cutouts are produced in the base sheet material by locally removing the base sheet through the use of laser irradiation. As an alternative, the first contact-making cutouts as well as the second contact-making cutouts can be produced by removing material with a laser.

Abstract: A control unit for a motor vehicle has a base plate with press-fit openings. A conductor track carrier is mounted on the base plate. The conductor-track carrier has electrical contacting tabs in the area of the press-fit openings. An electrical contact pin that projects from a supporting body is inserted into a press-fit opening in the base plate and there contacts the contacting tab. By virtue of a reserve of material which is reduced (used) as the contact pin is pressed in, the contacting tab is anchored in the press-fit opening in an essentially tension-less manner.

Abstract: A control unit for a motor vehicle has a base plate, a conductor track substrate, an electronic circuit making contact with the conductor track substrate, and a housing cover. A contacting panel with integrally constructed press-in openings adjoins the base plate. Projecting from a support body that overlaps the contacting panel are conductor ends which protrude into the press-in openings and make electric contact there with the conductor track substrate.
