ABSTRACT:
A fuel injection valve for internal combustion engines with a valve member which is displaced in a bore in a valve body by the fuel pressure, counter to the action of a closing spring. The valve body has at a combustion-space end, a valve head which on a side which faces the valve body is arranged a sealing surface which interacts with a valve seat provided on the combustion-space end of the valve body, forming a sealing cross section, and including injection apertures which permit a flow of fuel from a pressure space in the valve body to the combustion space of the internal combustion engines and has an aperture cross section which can be varied as a function of the stroke of the valve member. According to the invention, those parts which seal off the injection valve from the outside and those parts which form the aperture cross section of the injection openings are geometrically separated from one another, the sealing cross section which closes the valve off from the outside being arranged downstream, as seen in the injection direction, of the variable aperture cross section, which is situated radially to the inside.
