摘要： A fuel injection system which serves to supply fuel to an internal combustion engine. The fuel injection system includes a metering and quantity distribution valve with regulating valves connected at the output side, which valves can be influenced by the fuel pressure in a differential pressure control line. Communicating with a fuel supply line is a fuel reservoir, which has a flexible diaphragm which is displaceable by the fuel pressure counter to a reservoir spring in a spring chamber. Shortly before the end of the movement of the flexible diaphragm into the spring chamber, a spring plate resting on the flexible diaphragm opens a sealing valve via a stem. The sealing valve rests on the mouth of an outflow line, which leads via a control throttle to the differential pressure control line. A pressure maintenance valve is likewise disposed upstream of the sealing valve, and a line from a pressure limitation valve and a leakage line from the metering and quantity distribution valve discharge between the pressure maintenance valve and the sealing valve. The spring chamber of the fuel reservoir communicates via a return flow line with the fuel container.

摘要： The flow pump has an impeller (22), revolving in a pump chamber, which on each of its two axially oriented face ends (28, 29), has one ring of vanes (30) between which interstices (31) are located, and which cooperates with a feed channel (34) associated with the vanes (30) for pumping the fuel. When viewed in the radial direction relative to the rotary axis (24) of the impeller (22), the vanes (30) are positioned obliquely with respect to the rotary axis (24) in such a way that they lead ahead in the circumferential direction (21) of the impeller (22) toward the face end (28, 29) of the impeller (22). The vanes (30) and the rotary axis (24) of the impeller (22) form an angle (.alpha.) of between 25.degree. and 70.degree. that is oriented in the circumferential direction (21) of the impeller (22). Because of this obliquely positioned arrangement of the vanes (30), an improved inflow of the pumped fuel into the interstices (31) between the vanes (30) is effected, compared with an arrangement of vanes (30) that is parallel to the rotary axis (24), and as a result an increased feed pressure and improved efficiency of the flow pump are attained.

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： Aggregate for feeding fuel from a supply tank to an internal combustion engine of a motor vehicle has a feeding pump formed as a flow pump and including a disc-shaped rotatable impeller. A hydraulic buffer is formed between the impeller and the end walls of the pump chamber and includes recesses provided in a structure selected from the axial end surface of the impeller and the end walls of the pump chamber, so that the recesses are fillable with fuel during operation of the feeding pump and form the hydraulic buffer which acts in an axial direction of the impeller and stabilizes the impeller. An outer ring which connects the vanes of the impeller at their radially outer ends and limits the impeller in a peripheral direction. The recesses are arranged in a region of the outer ring.
