Device for supplying fuel from supply tank to internal combustion engine
of motor vehicle
摘要:
A device for supplying fuel from a supply tank to an internal combustion engine of a motor vehicle, has a pump chamber with end-side chamber walls and also having an inlet opening and an outlet opening, a drive motor, a supply pump having an impeller driven by the drive motor. The impeller rotates in the pump chamber and has a substantially disc-shaped hub part provided on its periphery with a plurality of radially outwardly extending vanes. At least one of the chamber walls in the region of radially outer ends of the vanes has an approximately ring shaped, groove-like supply passage which surrounds a rotary axis of the impeller. The inlet opening opens in a ring region of the pump chamber which is limited on one side by the hub part of the impeller and on the other side by an inner ring edge of the ring-shaped supply passage which surrounds the hub part with a distance from the latter.
