Fuel supply unit for vehicle internal combustion engine

摘要

The supply unit includes a supply pump (14) with disc-shaped supply member (26) in its pump chamber (29) formed by first and second wall parts (30,34) radially bounding an annular sector (35) which can be connected to either wall part. The first and second wall parts and the supply member (26), which is expanded in volume by a preliminary treatment, are positioned without play relative to each other. The first and second wall parts can be connected rigidly to each other.
