Abstract
A fuel injection pump for internal combustion engines, in particular one-cylinder diesel engines, has a pump piston (1) which can axially slide and rotate in a pump cylinder (13) with at least one fuel suction bore (14), a driving groove (6) arranged on the pump piston (1) parallel to the piston longitudinal axis, and geometrical connection between the front side (4) and the outer surface of the pump piston (1). In order to hydrodynamically regulate the optimum injection beginning during start, idle running and highest speed of rotation, a narrow slot (2,7) is provided as geometrical connection.
