Abstract
A fuel injection pump for internal combustion engines, in which a solenoid valve controlled by at least one of the state variables essential for operation of the engine, such as load, engine speed, pressure and temperature of combustion air, etc., controls the injection process by means of a shut-off device loaded by a spring on one end, the shut-off device being in one end position during the time of injection, but is subject to the feed pressure on both ends and is resting in the other end position while the pump is being filled. The chamber guiding the end of the slide-type shut-off device opposite the spring, is directly linked with the pump chamber of the high-pressure pump by a duct. In this manner the reversal of the slide takes place abruptly, which will permit a much better adaptation of the injection process to the different state variables of the combustion engine than before.
