摘要 |
The invention relates to a high-pressure pump (1) for conveying a fluid, particularly a fuel such as diesel, which comprises: a drive shaft (2) that has at least one cam (3); at least one piston (5); at least one cylinder (6) for mounting said at least one piston (5); and a roller shoe (9) that has a running roller (10) mounted therein (9) by means of a sliding bearing. The piston (5) is supported indirectly, using the roller shoe (9), on the drive shaft (2) with the at least one cam (3) such that said at least one piston (5) is able to carry out a translational movement on the basis of a rotational movement of the drive shaft (2), the sliding bearing on the roller shoe (9) comprising at least one recess outside of a sliding bearing operational contact surface. |
