Abstract
A pump/nozzle for internal combustion engines is proposed wherein the hydraulically driven pump piston is braked in its motion after the pressure line leading to the injection valve is closed. The braking is effected after delivery is ended by means of the fuel which is forced out of an end section of the pump work chamber which serves as a filling chamber. Braking or damping occurs with a delay by means of a throttle apparatus, and in a further embodiment, braking occurs simultaneously with the relief, to a lower standing pressure level of the pressure line.
