A fuel injection device for internal combustion engines has a fuel distributor which bears a plurality of connection pieces with radially projecting locking elements, and has a plurality of fuel injection valves, which are designed as so-called top-feed valves and are inserted fluid-tightly into the connection pieces. Provided to hold the fuel injection valves in the axial direction and to secure the fuel injection valves against rotation in the circumferential direction there is in each case a connecting member which engages in a circumferential groove in the valve casing and engages over the locking elements. In addition, the connection member has a fixing element which engages positively, at least in the circumferential direction, around a shaped element which is provided on the valve casing at a defined position.
Fuel injection device for internal combustion engines, with a fuel distributor which has a plurality of connection pieces bearing radially projecting locking elements, with a plurality of fuel injection valves which are inserted fluid-tightly by their end containing a connection opening into in each case one connection piece, and with a connecting member which, for the purpose of holding the fuel injection valve on the connection piece, on the one hand, engages in a circumferential groove on the valve casing and, on the other hand, engages over the locking element by means of two openings, to ensure a predetermined position of the fuel injection valve when the fuel injection valve is held on the connection piece, a shaped element being provided on the valve casing at a defined position and the connecting member bearing a fixing element which engages on the shaped element, provided at a distance on each connection piece (11) and essentially symmetrically to one another with respect to a plane (47) of symmetry extending through a center line (41) of the connection piece (11) are two locking elements (13, 30) which extend only part way in the circumferential direction of the connection piece (11), and each locking element (13, 30) is surrounded by one of the openings (25, 26).
