Abstract (en)
[origin: EP0686763A1] The fuel injection valve has a control piston (50), the opening and closing movements of which are controlled by two control spaces (70,74). The volume and fuel control pressure of the second one can be altered by the movement of the piston. The opening motion is slowed down by the pressure in the second control space, at least at first. For the closing movement, the control piston is accelerated at a certain pressure in the second control space to cut off the injection aperture (21) more rapidly. Relief elements (77) equalise the pressure between the second control space and the high pressure region. <IMAGE>
