Abstract: A fuel injection pump for internal combustion engines having a cup-shaped pump housing and a pump head enclosing the housing. The pump head has a cylinder in which a pump piston, which is set into simultaneous reciprocating and rotary motion by a cam drive, in the course of which it simultaneously acts as a distributor, encloses a pump work chamber that is filled with fuel upon an intake stroke and communicates with one of a plurality of injection lines upon the supply stroke. The resultant reaction forces and moments are supported according to the invention via a roller race supported directly on the pump head, and as a result the induction of force to the pump housing can be avoided.
