摘要： A fuel feed assembly with a feed pump of the roller-cell pump type, of which the pump rotor rotates eccentrically in a pumping chamber has a plurality of rollers which are guided in radial grooves of the disk-shaped pump rotor and are distributed uniformly over the circumference. When the pump rotor is rotating, the rollers run, as a result of the centrifugal force, on a bore wall of an intermediate ring radially delimiting the pumping chamber. The bore wall forms a running track. At the same time, the rollers delimit individual sickle-shaped pump rotor and the bore wall and the volume decreases from a suction port towards a delivery port as a result of the eccentricity of the pump rotor. At the same time, there is provided between the delivery port and suction port in the direction of rotation of the pump rotor a narrow-gap region which, according to the invention, is made so large that the pump working spaces passing through this region are closed completely.

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 aggregate has a feed pump formed as a flow pump (10) comprising an impeller (12) rotating in a pump chamber (24) which has a peripheral rim of vanes (32) on respective opposite sides of the impeller which together with opposing side walls (26,28) bounding the pump chamber (24) form respective lateral feed ducts (44). The vanes (32) of the impeller (12) are connected with each other by an outer ring (36) at their outer radial ends. The outer ring (36) of the impeller (12) similarly has respective additional rims of additional vanes (101) on opposite sides thereof. Both additional vane rims are separated from each other by an annular separating member (102) placed between them in an axial direction. The additional vanes (101) are arranged in succession with equal spacing (e) in a rotation direction around the impeller and are shaped to optimize fluid flow. The additional vanes (101) of the outer ring (36) together with the opposing side walls (26,28) and/or the annular wall (30) form at least one arc-shaped flow duct (94) extending around a rotation axis (13) of the impeller (12) in which a pressure build-up occurs in a rotation direction (11) of the impeller (13).

摘要： A fuel injection system is proposed which serves to supply fuel to an internal combustion engine. The fuel injection system includes a metering and quantity distributing valve connected with regulating valves, which can be acted upon by the fuel pressure in a differential pressure control line. Communicating with a fuel supply line are a pressure limiting valve and a switch member, the latter having a switch diaphragm which is displaceable into a return flow chamber by the fuel pressure counter to a switch spring and a closing spring. Upon this displacement, via a tappet, a spring plate resting on the switch diaphragm opens a sealing valve, which rests at the mouth of an outflow line, which via a control throttle leads to the differential pressure control line. The pressure limiting valve is located upstream of the sealing valve. The return flow chamber is arranged to communicate with the fuel container via a return flow line.

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.
