Abstract
There is proposed herein that a push rod of a fuel injection pump embodied as a radial piston pump which push rod further has a groove in its base be arranged to positively secure a roller in a relatively fixed position. The push rod is slidably guided in a hollow cylindrical wall in a sleeve. An apertured hub which forms an end wall of the sleeve has a slit, into which a prong which offstands axially from a fastening ring secured to said hub is arranged to protrude into said push rod. A helical spring supported by the sleeve presses a piston of the pump against the inside of the base of the push rod.
