Abstract

An injection valve for internal combustion engines has a filter element arranged on the inside of the injection valve in the fuel flow of the latter with ducts for the fuel. The filter element is designed as a throughflow heating element, for which purposes the walls of the throughflow ducts are capable of being heated, at least in certain regions, along their longitudinal extent.
