Abstract
A fuel injection pump formed as a radial piston pump having an encompassing cam ring, which drives pump pistons and a feed piston, which feed piston is embodied as a feed pump and is urged by a spring in the direction of the cam race. This arrangement results in a small size for the pump, in which sealing problems are substantially reduced and only a small idle fuel volume must be moved. By means of this fuel injection pump, a relatively high fill pressure in a pump work chamber is attained.
