<p>A fuel supply unit is proposed, in particular an assembly comprising a pumping element and an electromotor to drive it housed together in a common housing, which is secured in an upright position in the interior of a fuel container in such a manner that the pumping element is disposed near the bottom of the fuel container to enable aspiration of fuel from the fuel container until it is as nearly empty as possible. The pumping element has a first intake area oriented toward the bottom of the fuel container and a second intake area remote from the bottom of the fuel container, the second intake area being closable by a closure member movably disposed on the fuel supply unit whenever the fuel level in the fuel container drops below a predetermined level, so that fuel is then aspirated only via the first intake area. The closure member is actuatable by means of a floater body.</p> |
