Abstract
The present invention relates to a delivery pump, in particular for delivering diesel fuel into a high-pressure accumulator. The pump has a housing and a drive shaft which is accommodated in the latter and is mounted by at least one sliding bearing arrangement such that it can rotate about a drive shaft axis. The sliding bearing arrangement is formed by a bearing bore and a bearing shaft section which extends through the latter. The sliding bearing arrangement has a bearing play which extends in the radial direction between the bearing shaft section and the bearing bore and has a smaller value in the bearing center than at least one bearing edge. A delivery pump for delivering diesel fuel is therefore provided which has a low-wear sliding bearing arrangement.
