Abstract: A radial piston pump for generation of high fuel pressures in fuel injection systems comprises a pump housing, a pump shaft and at least one cylinder insert, arranged radially to the pump shaft. A cylinder chamber is located within the cylinder insert in which a piston can move back and forth. The cylinder insert is connected with a front face to a flattening of the pump housing, by connecting means. The cylinder insert comprises an inlet port and a high pressure port. The front face of the cylinder insert and/or the flattening of the pump housing comprise precisely machined raised sealing regions for sealing the cylinder insert against the pump housing, which are relatively small in relation to the total front face of the cylinder insert and the total flattening of the pump housing. A high surface pressure is thus achieved in the sealing region.

Abstract: The invention relates to a cam ring (2) for an injection pump for an internal combustion engine, comprising a round opening (4) for a shaft section, which can be eccentrically driven, and comprising a flattened outer section (6) against which a displacer element of the injection pump can be supported. A bush-shaped low-friction bearing means (12) for mounting the shaft section is provided inside the opening (4) of the cam ring (2). In order to reduce the problematic effects of pressing in the low-friction bearing means into the opening, the cam ring is designed so that the low-friction bearing means (12) in one form comprises a polymer-based bearing coating material (14) with friction-reducing fillers, which is directly placed upon the surface (16) of the cam ring (2) that delimits the opening (4).
