HIGH-PRESSURE FUEL PUMP

摘要

In order to improve the cycle times and to reduce the error rates during the production of a high-pressure fuel pump (28) having at least one piston (30), on which a sealing device (74) that radially surrounds the piston (30) is arranged, the sealing device (74) comprising a seal carrier (68) and said seal carrier (68) being connected, at least in sections, to a housing (50) of the fuel pump, the seal carrier (68) has at least one radially peripheral portion (93, 94) in which the seal carrier (68) and the housing (50) are materially bonded together by way of capacitor discharge welding.
