  • Patent number: 10227959
    Abstract: The invention relates to a high pressure fuel pump (10) comprising a housing (12) and a flange (14) by means of which the housing (12) can be fastened to an engine block or cylinder head, the flange (14) being formed of at least two flange parts (26) that are separate from the housing (12) and are separated from each other, and that overlap mutually in the fastened state of the housing (12).
    Type: Grant
    Filed: June 2, 2016
    Date of Patent: March 12, 2019

  • Patent number: 9989028
    Abstract: A pressure limiting valve for a fuel injection system may include a sleeve, a fixing pin, a spring, a sealing element, and a seat. The sleeve may have a longitudinal axis. The fixing pin protruding through a cavity enclosed by the sleeve. The spring may have a first end supported on the sleeve and a second end supported by the sealing element. The seat may provide a sealing surface for the sealing element to block a fluid flow through the valve when closed position, and allow this flow to pass in other positions. The outer circumference of the sleeve may vary within predefined tolerances along the longitudinal axis. The fixing pin may be shaped to plastically deform by a movement of the fixing pin along the longitudinal axis, in order to press the sleeve into the housing.

  • Patent number: 8840083
    Abstract: An intake valve for a cylinder of the high-pressure fuel pump of a common rail injection system has a valve body with an inlet opening and a closing member. The closing member closes the inlet opening in a first end position. The member can be moved relative to the inlet opening depending on a pressure difference. The intake valve has a non-linear volumetric flow characteristic.
