Abstract

A known fuel injection valve that can be secured to a fuel distributor by rotating the fuel injection valve about a longitudinal valve axis. A first electrical contact element extends out of the valve housing, parallel to the longitudinal valve axis. Such fuel injection valves can be electrically contacted by a bank of contacts that can be mounted on the fuel distributor in a direction of the longitudinal valve axis. The novel fuel injection valve includes first electrical contact elements which extend radially outward. By rotating the fuel injection valve about its longitudinal valve axis, an electrically conductive connection can be made between first electrical contact elements and second electrical contact elements that electrically contact the connection in the fuel injection valve. In this way, a simple, very compact, safe and secure electrical contacting of the fuel injection valves is attained The electrically actuatable fuel injection valve according to the invention is especially suitable for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
