  • Check valve, high-pressure component, and high-pressure fuel pump
    Patent number: 10746148
    Abstract: Various embodiments include a check valve for a high-pressure component in a fuel injection system comprising: a valve housing with a valve hole having an inner diameter; a valve seat and a sealing element arranged in the valve hole; and a coil spring pushing the sealing element toward the valve seat along a longitudinal axis of the valve hole. The coil spring includes a plurality of coil turns each having an outer diameter. In a non-assembled state of the check valve, the outer diameter of at least one of the coil turns is greater than the inner diameter of at least a portion of the valve hole, so that in an assembled state of the check valve, the coil spring is secured in a force-fitting manner in the valve hole.
