Abstract
The invention relates to a pressure regulator for controlling a pre-injection quantity of fuel in internal combustion engines, preferably Diesel engines, with a control piston which is connected in a first position with a relief valve for producing a decreased pressure on an injection valve and which, in a second, subsequent position can be separated from the relief valve for producing a higher pressure.
