  • Patent number: 10837430
    Abstract: Embodiments relate to a high-pressure fuel pump having a pump piston which, during operation, moves in translation between a pressure chamber and a leakage chamber. The leakage chamber has a leakage collecting region and an equalizing region. A low-pressure damper having a bellows-shaped corrugated damper plate is arranged in the equalizing region.

  • Patent number: 10781778
    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.

  • Publication number: 20190085806
    Abstract: Some embodiments may include a valve for a pump comprising: a first stop element having a longitudinal axis and a sealing seat; an actuator providing an actuator force along the longitudinal axis; a pin movable relative to the first stop element along the longitudinal axis and movable by the actuator force; a sealing element moved by the pin relative to the valve seat in order to open or close the valve; and a second stop element rigidly fastened to the first stop element providing a stop for the sealing element to limit movement of the sealing element away from the sealing seat along the longitudinal axis. The second stop element is fastened at a defined predetermined distance from the first stop element to define a spacing between the sealing seat and the stop.

  • Patent number: 9947449
    Abstract: An electromagnetic actuator includes an electromagnet having a coil, which coil surrounds a pole core, and a magnet armature, which can be moved toward the pole core by the electromagnet, wherein the magnet armature has a bearing surface facing the pole core and the pole core has a correspondingly opposite counter surface. The bearing surface and/or the counter bearing surface has a layer that prevents direct contact of the bearing surface with the counter bearing surface and that causes damping of the approaching movement.

  • Publication number: 20160237973
    Abstract: The present disclosure describe a valve comprising a control unit for controlling a valve element, an electromagnet, and a valve element. The control unit may include an armature group. The electromagnet may include a coil and a pole core. The armature group may include a magnet armature moved by the electromagnet, an intermediate element, and a control pin for controlling the valve element. The control pin may be connected to the magnet armature via the intermediate element and moved together with the magnet armature. The intermediate element may be resilient and couple the control pin resiliently to the magnet armature.

  • Patent number: 9383028
    Abstract: A valve includes a spring with a spring force, an actuator with an actuator force which can act against the spring force, a pin which can be actuated by the actuator, a sealing element which can be coupled with the pin, and a seal seat such that the valve is closed when the sealing element rests against the seal seat. The pin can be moved in the direction of the sealing element by means of the actuator, and the pin can be moved in the direction away from the sealing element by means of the spring. The sealing element can be moved into an open position independently of the pin, wherein a fluid flow through the valve is released in the open position.
