    摘要： The flow pump has an impeller, driven in a pump chamber and having a ring of blades spaced apart from one another in the circumferential direction on at least one end face and ending at the face end of the impeller and cooperate therewith to define blade chambers. In the pump chamber, at least one feed conduit in the form of a split ring cooperates with the ring of blades on the impeller, and at least one intake opening discharging into the feed conduit is embodied in a pump chamber wall that defines the pump chamber in the direction of the pivot axis of the impeller. In an initial region at the at least one intake opening and/or in the circumferential direction of the impeller, adjoining the impeller, the feed conduit extends radially farther inward than the blade chamber bottom of the impeller, and the transition between a radially inner blade chamber bottom of the blade chambers and the associated face end of the impeller has a chamfer or rounded corner.

    摘要： A unit for delivering fuel from a supply tank to an internal combustion engine, having a disklike impeller driven to revolve in a pump chamber, on whose circumference a number of blades are disposed, and having at least one supply conduit, disposed in the region of the impeller blades and open toward the impeller, in a chamber wall defining the pump chamber on the face end and axially adjoining the impeller, which supply conduit extends via a split ring around the pivot axis of the impeller from an inlet opening into the pump chamber to an outlet opening from it. In order to assure that sufficient fuel can be aspirated unthrottled in the presence of gas bubbles in the fuel, in particular when the fuel is hot, the supply conduit is embodied in the region of the inlet opening as larger by a factor of 2 than the usual supply conduit cross section; the cross section of the supply conduit then decreases continuously, beginning at the inlet end, forming a compression conduit.

    摘要： The apparatus for supplying fuel includes a fuel tank and a fuel feed unit in the fuel tank. The fuel feed unit has a main housing, a suction cover arranged in a bottom part of the main housing, a fuel pump and a degassing valve arranged in the suction cover for degassing the fuel pump. The fuel pump itself includes an impeller housing with a circular passage for fuel flow and an electric-motor-driven impeller. The impeller housing is arranged in the main housing and next to the suction cover and it is provided with a degassing passage connecting the circular passage with the degassing valve. To improve starting behavior the fuel feed unit has a degassing valve in the suction cover, which is connected with the circular passage of the impeller housing by a degassing passage. The degassing valve opens to the fuel tank when pressure in the degassing passage exceeds a predetermined value for degassing the fuel pump. The degassing valve can be a spring-loaded ball valve in which the compression spring bearing on the ball provides a predetermined counter-force so that the degassing valve is kept open during idle and start of impeller rotation until degassing is complete.
