A delivery unit arranged in a surge chamber of a fuel tank includes an ejector for filling the surge tank. One half of the ejector is defined by the surge chamber and the other half is defined by a pump holder holding a fuel pump in the surge chamber. The pump holder and the surge chamber are configured as components which are easy to manufacture, thereby allowing the delivery unit to be cost-effectively configured.

Delivery unit arranged in a surge chamber of a fuel tank of a motor vehicle

A delivery unit which is provided for feeding motor-vehicle fuel has an electric motor ( ) with vanes ( ) arranged on the lateral surface of a rotor ( ). During rotation of the rotor ( ), the vanes ( ) feed the fuel in a pump channel ( ) between the rotor ( ) and a stator ( ). The delivery unit is thus constructed in a particularly compact manner and is cost-effective to produce.

Delivery unit

A pump assembly is comprised of a pump member having a pump wall and a filter element located within a filter housing that is prestressed against the pump wall. In an exemplary embodiment, a housing of the pump assembly is manufactured in a single piece with a clamping element. The clamping element includes a flanged border for gripping behind an edge of the filter housing.
