    摘要: A fixing device for reciprocally fixing a fuel injection valve to a cylinder head of an internal combustion engine and for fixing the fuel injection valve to a fuel distributor line, comprising two spring tongue elements (2) which can be inserted into a retaining groove of the fuel injection valve or the fuel distributor line. The center distance (d1) of the spring tongue elements (2) is less than the largest diameter (d2) of the opening surface surrounded thereby and the spring tongue elements (2) are resilient in a radial direction in relation to an axis of the fuel injection valve. At least two spring elements (4) are formed in an axial direction in relation to the spring tongue elements and are resilient with respect to traction and pressure. Said spring elements can be detachably linked to the opposite-lying fuel injection valve or fuel distributor line in an axial non-positive fit by means of a locking connection.

    摘要: The invention relates to a fuel injection system, comprising at least one fuel distributor (11) and at least one fuel injection valve (1). Said fuel distributor (11) is designed as an independent component and presents several valve housings (16) having inner longitudinal openings (17), in which the fuel injection valves (1) can be introduced. Said valve housings (16) terminate with the ends (18) thereof, opposed to a fuel supply channel (13) of the fuel distributor (11), lying freely. At least one safety element (20) for the captive fastening of the corresponding fuel injection valve (1) is shaped at said ends (18) of the valve housings (16). Said fuel injection system is particularly suitable for use in mixture-compressing spark-ignition internal combustion engines.
