Abstract
The invention relates to an injection valve () comprising a booster piston (), said piston delimiting a pump chamber () and a booster chamber (). A valve () is provided in the inlet to the chamber (). The valve is configured as a 3/2-way valve and controls the pressure in the pump chamber (). The pressure in the pump chamber () is converted into a correspondingly increased pressure in the booster chamber () and in an injection chamber () containing an injection needle (), by means of the booster piston (). The use of the valve () allows a precise control of the injection times.
