    摘要： The invention relates to a high-pressure fuel pump for a fuel injection system of an internal combustion engine, with a pump housing (2) and with at least one pump element (3) which comprises a piston (8) which is driven by a cam (18) which interacts with a roller (15), the free ends of which are bounded by two side run-on surfaces which come into contact with mating surfaces during the operation of the high-pressure fuel pump (1). In order to provide a high-pressure fuel pump which can be produced cost-effectively and has a long service life, the side run-on surfaces are designed as circular ring disc surfaces and, in a central internal region, are released from contact with the mating surfaces.

    摘要： The invention relates to a piston pump, in particular a high-pressure fuel pump, comprising a housing (1), a piston and a drive shaft (2) having a cam section (3) on which the piston is at least indirectly supported via a guide roller (5) that is rotatably mounted in a roller plunger (4), wherein laterally on either of the two sides of the cam section (3) a rim (6) is provided that protrudes in the radial direction beyond the cam section (3), wherein the rim (6) tapers on one front face directed towards the guide roller (5) to an outer circumference of the rim (6), wherein the rim (6) is in particular conical, so that an angular opening results, wherein the cam roller comprises a convex curvature directed towards the rim (6), preferably with a radius (r). Alternatively, also the rim can have a convex curvature and the roller can taper conically.

    摘要： The invention relates to a pump, in particular a high-pressure fuel pump, having a housing (10,16,17) in which a drive shaft (12) is disposed by means of which at least one pump element (22) is moved. The drive shaft (12) is mounted in the housing (10,16,17) in a rotatable fashion via at least one bearing (14,15) configured as a sliding bearing. In at least one axial edge region (X) of the at least one bearing (14,15), the region facing a load application region (18) of the drive shaft (12) for the at least one pump element (22), the housing (16,17) and/or the drive shaft (12) are reduced in the cross-section thereof such that, when a load is applied to the drive shaft (12) while driving the at least one pump element (22), the housing (16,17) and/or the drive shaft (12) in the axial edge region (X) of the at least one bearing (14,15) is elastically deformed perpendicularly to the rotational axis (13) of the drive shaft (12). This reduces the pressure on the bearing (14,15) in the axial edge region (X), which allows the bearing (14,15) to have smaller dimensions, because a more uniform load is applied to said bearing across the axial extension thereof.
