摘要： An aggregate for feeding fuel from a supply tank to an internal combustion engine of a motor vehicle has a feed pump formed as a flow pump and having a disk-shaped impeller and a pump chamber in which the impeller rotates and which is limited in an axial direction by two end walls spaced from one another and in a radial direction by a ring wall arranged so that substantially parallel axial gaps are formed between end surfaces of the impeller and end surfaces of the pump chamber facing the end surfaces of the impeller. Each of the axial gaps has an inner ring-shaped throttle gap with an inner throttle gap area and an outer ring-shaped throttle gap with an outer throttle gap area as considered in a radial direction and formed so that when the axial gaps are identical at any distance from the rotary axis the inner and outer throttle gap areas are identical, but when the axial gaps are not identical, then at a side of a smaller axial gap the inner throttle gap area is greater than the outer throttle gap area and at the side of a greater axial gap the outer throttle gap area is greater than the inner throttle gap area.

摘要： The peripheral pump includes a wall bounding a pump chamber and provided with a substantially annular delivery port with a base having a circular segment with a center; a circular cylindrical impeller revolving in the pump chamber, having two end faces and a rim of blades disposed at intervals along a circumference of the impeller so that a groove-like gap is formed between two adjacent blades, the groove-like gap having a base, as seen in a longitudinal section through the pump, having a circular segment with a center substantially coincident with the center of the circular segment of the delivery port, the center of the circular segments being located within an outer contour of the impeller.
