Abstract

A high-pressure fuel pump includes a housing, at least one piston, and a sealing device. The device is positioned on the piston so as to surround the piston, and includes a seal carrier. The carrier is connected, at least in sections, to the housing, and includes at least one radially peripheral portion that is materially bonded to the housing via a capacitor discharge weld connection. Such a pump enables improved cycle times and reduced error rates during production.
