Abstract
A suction device for a fuel feed unit in which the suction device has a rigid suction tube on which a suction head is arranged. The suction head is formed as a conically widening elastic bellows having a large suction opening which faces the bottom with a screen arranged in the opening. As a result of the development as an elastic bellows, the suction opening is held resting with initial spring tension (i.e., resilient prestress biasing) against the bottom of the fuel tank.
