| 摘要 |
The invention relates to a fuel conveyor for a combustion engine, comprising a housing (1) for receiving at least one conveyor module, and a drive shaft (2) for driving said conveyor module, the drive shaft (2) being rotatably mounted in a bearing bore (3) of the housing (1) and at least two sealing arrangements (4, 5), axially spaced apart from one another, being arranged inside said bearing bore (3) to seal off a fuel-guiding inner region (6) from a lubricant-guiding outer region (7). According to the invention, the sealing arrangement (5) that is effective against the lubricant-guiding region (7) is arranged on a shaft section (a) of the drive shaft (2) designed to be at least partially tapered such that said shaft section (a) has an outer diameter (D2) smaller than the outer diameter (D1) of the drive shaft (2) in the region of the receptacle of the sealing arrangement (5) effective against the fuel-guiding region (6). |
