Fuel-conveying system for internal combustion engine, has housing for incorporating conveying module and drive shaft for driving transport module

摘要

The fuel-conveying system has housing (1) for incorporating a conveying module and a drive shaft (2) for driving a transport module. The drive shaft is pivoted in a bearing bore (3) of the housing. Two sealing arrangements are axially distanced and are arranged inside the bearing bore for sealing a fuel guiding inner area (6) against a lubricant guiding outer area (7). A sealing arrangement (4) has a shaft sealing (8) and another sealing arrangement (5) has two other seals (9,10,11) or a gasket in combination with another shaft sealing (8) or axial shaft gasket.
