  • Patent number: 10371109
    Abstract: A high-pressure fuel supply pump in which a relief valve mechanism is not detached by a force generated by a differential pressure between an inlet side and an output side of a relief valve mechanism is obtained. According to the present invention, in order to obtain the high-pressure fuel supply pump, the relief valve mechanism of the high-pressure fuel supply pump is oriented from a downstream side of a discharge valve to an upstream side of the discharge valve, and the output side of the relief valve mechanism is inserted from the upstream side of the discharge valve into the pump housing, and the relief valve mechanism is fixed with press fitting. Therefore, a force exerted by the differential pressure between the inlet side pressure and the output side pressure of the relief valve mechanism is exerted in a direction in which the relief valve mechanism is inserted, so that the relief valve mechanism can be prevented from being detached.
