Abstract

In known devices, the fuel injection valves, disposed in individual receiving bores, are retained individually with clamping shoes, and electrical contact is provided by individual electric plugs. The novel device is intended to assure that all the fuel injection valves are retained and provided with electrical contact simultaneously. The fuel injection valves inserted into receiving bores of a basic body are retained in common in the receiving bores by means of a contact-making outlet strip, slipped onto the basic body, and are electrically connected in common by means of electrically conductive contact elements. The entire compact device can be fastened as a unit to the engine and electrically connected, via a connection plug to an electronic control unit for trigging the fuel injection valves. The device makes adaptation to various engine types possible.
