Abstract
What follows is a description of an improved fuel injection pump for an internal combustion engine. The pump includes a rotating and reciprocating piston which distributes fuel through a fuel passage provided in the pump for each fuel injection nozzle of the pump. To avoid the adverse effects which result from the reduced fuel pressure during the suction stroke of the pump, an improved pressure relief apparatus is provided. The improvement resides in two coaxially disposed blind bores in the piston and associated radial bores extending radially from the blind ends thereof. The coaxially disposed blind bore and its associated radial bore closest to the working chamber of the pump serve as a passage for supplying fuel to be distributed and as a passage through which fuel is distributed, while the coaxially disposed bore farthest from the working chamber of the pump includes a spring-loaded valve which opens in the pressure relief direction.
