The invention relates to a high-pressure fuel pump (28) comprising a piston (30) which has, arranged on its end section oriented toward a drive, a sealing device (74) which radially surrounds the piston (30), wherein the piston (30) can be displaced relative to the sealing device (74) along a longitudinal axis (64). According to the invention, the sealing device (74) has a first and a second radially inner circumferential sealing section (78), wherein the first and second sealing sections (78) are arranged at mutually separated axial end regions of the sealing device (74), and wherein the sealing sections (78) are present on an injection-molded part (77) that has been reworked in a chip-removing manner. |
