Abstract

The device has a fuel injecting valve (1) fastened directly to a fuel distribution line (4) by a connection body (18). The valve is retained in the body such that the valve and body are placed without abutment on all surfaces of a mounting hole in a cylinder head, where the surfaces extend in non parallel direction to the valve. Damper plates (26) are provided in connection region of the distribution line and cylinder head.
