  • Piston fuel pump for an internal combustion engine
    Patent number: 10400727
    Abstract: A piston fuel pump for an internal combustion engine includes a pump cylinder and a pump piston that is configured to be axially displaced in the pump cylinder. A working chamber is defined by the pump piston. A seal is provided on the pump cylinder, which seals the working chamber counter to a low pressure region. The seal is applied directly to the pump piston by an injection molding method.
    Type: Grant

  • Piston fuel pump for an internal combustion engine
    Patent number: 10288025
    Abstract: A piston fuel pump for an internal combustion engine includes a pump cylinder, a pump piston, and a seal. The pump piston is configured to be moved axially in the pump cylinder, wherein a working chamber is delimited by the pump piston. The seal is disposed on the pump piston and seals off the working chamber from a low-pressure region. The seal seals off an end section of the pump piston adjacent to the working chamber from the working chamber.

  • Method for producing a throttle valve unit in a two-component injection molding process
    Patent number: 7790083
    Abstract: A method for manufacturing a throttle valve unit having a housing part and a valve flap part that can move in relation to it includes the steps of injection molding the housing part of a first plastic material in a first cavity, transferring the molded housing part to a second cavity spatially decoupled from the first cavity, and injection molding the movable valve flap part out of a second plastic material in a second mold cavity inside the molded housing part. Before the molded housing part is transferred to the second cavity, it is subjected to an intermediate treatment in order to influence the shrinkage behavior, thereby selectively adjusting the gap geometries between the parts.
