High-pressure pump

A high pressure pump (1) for delivering a fluid, the high pressure pump comprising

• a drive shaft (2) with at least one cam (3),
• at least one piston (5),
• at least one cylinder (6) in which the at least one piston (5) is mounted,
• the at least one piston (5) being supported on the drive shaft (2) with the at least one cam (3), with the result that a translational movement can be carried out by the at least one piston (5) on the basis of a rotational movement of the drive shaft (2), and
• at least one covering cap (8) which is fastened indirectly to the cylinder (6) on an outer side,
• wherein an end (18) of the at least one covering cap (8) lies on a projection (16) of the high pressure pump (1) in order to fasten the end (18) of the covering cap (8) to the projection (16) in a positively and non-positively locking manner, and
• wherein the at least one covering cap (8) lies on the high pressure pump (1) with an elastic prestressing force.
