Abstract
Feed pumps operating on the side channel or peripheral principle are known from use in fuel feed units of motor vehicles. These feed pumps often have rings of blade chambers, which are delimited by moving blades, said rings being located opposite one another in an impeller. Impellers, of which the moving blades of blade chambers located opposite one another are arranged in a V-shaped manner in relation to one another, already achieve high efficiencies. The new feed pump is to have improved efficiency, as compared with these. The moving blades of the feed pump are arranged at an angle to the axis of rotation of the impeller, this angle of the moving blades increasing from the radially inner to the radially outer region in proportion to the radial extent of the moving blade. The feed pump is suitable particularly for use in a fuel feed unit in a motor vehicle.
