<p>The invention relates to a high-pressure pump for a fuel injection device of an internal combustion engine, comprising at least one pump element having a pump piston (1) that can be driven via a cam (2) or eccentric disk of a drive shaft in a stroke movement, wherein the pump piston (1) is directly supported via a tappet body (3) and a roller (4) on the cam (2) or eccentric disk of the drive shaft, and wherein a roller shoe (5) is provided with a substantially partially cylindrical recess (6) for partially receiving the roller (4) in the tappet body (3). According to the invention, the substantially partially cylindrical recess (6) of the roller shoe (5) forms longitudinal edges (7) with an end surface (8) of the roller shoe (5), which are designed in a rounded or chamfered manner, for receiving a coating (9) that extends from the recess (6) over the longitudinal edges (7).</p> |
